The Great Saturated Fat Myth: How 60 Years of Flawed Science Built a Dietary Villain

Introduction: The Fat We Were Told to Fear

For the better part of 60 years, the message from doctors and public health officials has been clear and consistent: to protect your heart, you must avoid saturated fat. Foods like butter, red meat, and cheese were cast as dietary villains, directly responsible for clogging arteries and causing heart disease. This advice became a cornerstone of modern nutrition, shaping how billions of people eat.

But the scientific story behind this advice is far more complex than most people realize. It’s a history filled with surprising twists, questionable data, influential personalities, and crucial studies that were buried for decades. The seemingly solid consensus was, in fact, built on a foundation that is now being challenged by re-discovered evidence. Here are five surprising takeaways from the convoluted history of saturated fat.

1. The “Diet-Heart Hypothesis” Has a Surprisingly Flawed Origin Story

The idea that saturated fat causes heart disease by raising cholesterol, known as the “diet-heart hypothesis,” was first proposed in the 1950s by physiologist Ancel Keys. The bedrock evidence used to support this theory was Keys’s influential Seven Countries Study, which for decades was cited as definitive proof of the link.

However, a closer look at the study reveals major shortcomings. Critics have long pointed out that Keys used a “nonrandom approach” to select the countries, leading to accusations that he “cherry picked” nations likely to confirm his hypothesis. For example, he did not include countries like France or Switzerland, where people ate a great deal of saturated fat but had low rates of heart disease.

The problems went deeper than just country selection:

• Flawed Dietary Data: Dietary information was sampled from only 3.9% of the men in the study, totaling fewer than 500 participants.

• The Lent Omission: The data collection on the Greek island of Crete suffered from what later researchers called a “remarkable and troublesome omission.” The dietary sample was taken during Lent, a period when the Greek Orthodox church banned “all animal foods.” This meant saturated fat consumption was almost certainly undercounted, yet this skewed data became a cornerstone of the argument that the famously healthy “Cretan diet” was low in saturated fat.

2. Major Studies That Contradicted the Hypothesis Were Left Unpublished

While the diet-heart hypothesis was gaining widespread acceptance, several large and rigorous clinical trials were conducted to test it. Shockingly, when the results contradicted the prevailing theory, they were often ignored or simply not published.

Two critical examples stand out:

• The Minnesota Coronary Experiment (MCE): Conducted between 1968 and 1973, this was the largest test of the diet-heart hypothesis ever performed, involving over 9,000 men and women in one nursing home and six state mental hospitals. Despite successfully lowering participants’ cholesterol, the study found no reduction in cardiovascular events, cardiovascular deaths, or total mortality. The results went unpublished for 16 years.

• The Framingham Heart Study: This landmark study is one of the most famous health investigations in history. Yet, a detailed dietary investigation completed in 1960 concluded there was “No relationship” between saturated fat consumption and heart disease. This crucial finding was not publicly acknowledged by a study director, William P. Castelli, until 1992.

Why would the results of such a major trial like the MCE be withheld for so long? The study’s principal investigator, Ivan Frantz, reportedly explained his decision with a simple, telling admission:

“We were just disappointed in the way it came out.”

3. Swapping Saturated Fat for Vegetable Oil Lowered Cholesterol—But Was Linked to a Higher Risk of Death

When the long-lost data from the Minnesota Coronary Experiment (MCE) was finally recovered and re-analyzed decades later, it revealed a stunning and deeply counter-intuitive finding. The study’s intervention, which replaced saturated fats with vegetable oils rich in linoleic acid (like corn oil), was successful in its primary biochemical goal: it lowered participants’ serum cholesterol by an average of 13.8% compared to the control group.

According to the diet-heart hypothesis, this should have led to fewer deaths. Instead, the opposite happened. The re-analysis showed no mortality benefit at all. More strikingly, it uncovered a dangerous paradox: for each 30 mg/dL reduction in serum cholesterol, there was a 22% higher risk of death.

This finding is monumental because it directly challenges the core assumption that lowering cholesterol through this specific dietary change—swapping saturated fat for vegetable oils high in linoleic acid—automatically translates to better health and a longer life.

4. Major Conflicts of Interest May Have Shaped the Official Advice

The official dietary advice to limit saturated fat wasn’t just shaped by flawed science; it was also influenced by powerful financial interests.

In 1961, the American Heart Association (AHA) became the first major organization to recommend that Americans limit saturated fat. What is less known is that in 1948, the AHA received a transformative donation of $1.7 million (about $20 million in today’s dollars) from Procter & Gamble, the makers of Crisco oil. This product, made from polyunsaturated vegetable oil, benefited directly from advice to avoid traditional animal fats. According to the AHA’s own official history, this donation was the “bang of big bucks” that launched the group into a national powerhouse.

This pattern of potential conflicts has persisted. An analysis of the 2020 U.S. Dietary Guidelines for Americans (DGA) advisory committee found numerous conflicts, including members with extensive funding from the soy and tree nut industries—which benefit from recommendations favoring polyunsaturated fats—and members who were openly plant-based advocates.

This raises serious questions about the objectivity of the guidelines, especially for specific numerical caps. In a private email obtained through a Freedom of Information Act request, the Vice-Chair of the 2015 DGA committee made a frank admission about the 10% limit on saturated fat:

“There is no magic/data for the 10% number or 7% number that has been used previously.”

5. The “Scientific Consensus” Isn’t as Solid as You Think

Over the past decade, the evidence challenging the diet-heart hypothesis has mounted significantly. More than 20 review papers by independent teams of scientists have now been published, largely concluding that saturated fats have no significant effect on cardiovascular disease, cardiovascular mortality, or total mortality.

The debate continues to play out in major scientific journals, with different meta-analyses reaching conflicting conclusions. For example, a 2020 Cochrane review found that reducing saturated fat led to a 21% reduction in cardiovascular events(like heart attacks and strokes) but had little effect on the risk of dying. In contrast, a 2025 systematic review in the JMA Journal found no significant benefit for either mortality or cardiovascular events. A key reason for these conflicting results is the inclusion of flawed trials; the JMA Journal review, for example, criticized other meta-analyses for including data from studies like the Finnish Mental Hospital Study, which was not properly randomized.

Despite this fierce and ongoing scientific debate, the new evidence has not yet been reflected in official dietary policies, which remain largely based on the older, contested science. As the authors of the 2025 JMA Journal meta-analysis bluntly concluded:

“The findings indicate that a reduction in saturated fats cannot be recommended at present to prevent cardiovascular diseases and mortality.”

Conclusion: A New Perspective on Fat

The history of the war on saturated fat serves as a powerful cautionary tale. It reveals how a scientific hypothesis, born from flawed studies and propelled by influential advocates, can become entrenched as government policy and public dogma, even as contradictory evidence is ignored, buried, or dismissed.

For decades, we’ve been told a simple story about fat, but the reality is that much of this advice was based on a shaky scientific foundation, compromised by unpublished trials and significant conflicts of interest. The conversation is finally changing, but it took the recovery of long-lost data to force a re-examination of decades-old beliefs.

It took decades and recovered data to question the war on fat. What official advice are you following today that might be based on a similarly fragile foundation?

Process to Agentic Artificial Intelligence A

n this interview. I interview myself as well utilize a voice aid while I recover

Artificial intelligence seems like magic to most people, but here’s the wild thing – building AI is actually more like constructing a skyscraper, with each floor carefully engineered to support what’s above it.

That’s such an interesting way to think about it. Most people imagine AI as this mysterious black box – how does this construction analogy actually work?

Well, there’s this fascinating framework called the Metadata Enhancement Pyramid that breaks it all down. Just like you wouldn’t build a skyscraper’s top floor before laying the foundation, AI development follows a precise sequence of steps, each one crucial to the final structure.

Hmm… so what’s at the ground level of this AI skyscraper?

The foundation is something called basic metadata capture – think of it as surveying the land and analyzing soil samples before construction. We’re collecting and documenting every piece of essential information about our data, understanding its characteristics, and ensuring we have a solid base to build upon.

You know what’s interesting about that? It reminds me of how architects spend months planning before they ever break ground.

Exactly right – and just like in architecture, the next phase is all about testing and analysis. We run these sophisticated data profiling routines and implement quality scoring systems – it’s like testing every beam and support structure before we use it.

So how do organizations actually manage all these complex processes? It seems like you’d need a whole team of experts.

That’s where the framework’s five pillars come in: data improvement, empowerment, innovation, standards development, and collaboration. Think of them as the essential practices that need to be happening throughout the entire process – like having architects, engineers, and specialists all working together with the same blueprints.

Oh, that makes sense – so it’s not just about the technical aspects, but also about how people work together to make it happen.

Exactly! And here’s where it gets really interesting – after we’ve built this solid foundation, we start teaching the system to generate textual narratives. It’s like moving from having a building’s structure to actually making it functional for people to use.

That’s fascinating – could you give me a real-world example of how this all comes together?

Sure! Consider a healthcare AI system designed to assist with diagnosis. You start with patient data as your foundation, analyze patterns across thousands of cases, then build an AI that can help doctors make more informed decisions. Studies show that AI-assisted diagnoses can be up to 95% accurate in certain specialties.

That’s impressive, but also a bit concerning. How do we ensure these systems are reliable enough for such critical decisions?

Well, that’s where the rigorous nature of this framework becomes crucial. Each layer has built-in verification processes and quality controls. For instance, in healthcare applications, systems must achieve a minimum 98% data accuracy rate before moving to the next development phase.

You mentioned collaboration earlier – how does that play into ensuring reliability?

Think of it this way – in modern healthcare AI development, you typically have teams of at least 15-20 specialists working together: doctors, data scientists, ethics experts, and administrators. Each brings their expertise to ensure the system is both technically sound and practically useful.

That’s quite a comprehensive approach. What do you see as the future implications of this framework?

Looking ahead, I think we’ll see this methodology become even more critical. By 2025, experts predict that 75% of enterprise AI applications will be built using similar structured approaches. It’s about creating systems we can trust and understand, not just powerful algorithms.

So it’s really about building transparency into the process from the ground up.

Precisely – and that transparency is becoming increasingly important as AI systems take on more significant roles. Recent surveys show that 82% of people want to understand how AI makes decisions that affect them. This framework helps provide that understanding.

Well, this certainly gives me a new perspective on AI development. It’s much more methodical than most people probably realize.

And that’s exactly what we need – more understanding of how these systems are built and their capabilities. As AI becomes more integrated into our daily lives, this knowledge isn’t just interesting – it’s essential for making informed decisions about how we use and interact with these technologies.

What is a Data Anomaly? A Bike Shop Investigation

Introduction: Finding Clues in the Data

In the world of data, an anomaly is like a clue in a detective story. It’s a piece of information that doesn’t quite fit the pattern, seems out of place, or contradicts common sense. These clues are incredibly valuable because they often point to a much bigger story—an underlying problem or an important truth about how a business operates.

In this investigation, we’ll act as data detectives for a local bike shop. By examining its business data, we’ll uncover several strange clues. Our goal is to use the bike shop’s data to understand what anomalies look like in the real world, what might cause them, and what important problems they can reveal about a business.

——————————————————————————–

1.0 The Case of the Impossible Update: A Synchronization Anomaly

1.1 The Anomaly: One Date for Every Store

Our first major clue comes from the data about the bike shop’s different store locations. At first glance, everything seems normal, until we look at the last time each store’s information was updated.

The bike shop’s Store table has 701 rows, but the ModifiedDate for every single row is the exact same: “Sep 12 2014 11:15AM”.

This is a classic data anomaly. In a real, functioning business with 701 stores, it is physically impossible for every single store record to be updated at the exact same second. Information for one store might change on a Monday, another on a Friday, and a third not for months. A single timestamp for all records contradicts the normal operational reality of a business.

1.2 What This Anomaly Signals

This type of anomaly almost always points to a single, system-wide event, like a one-time data import or a large-scale system migration. Instead of reflecting the true history of changes, the timestamp only shows when the data was loaded into the current system.

The key takeaway here is a loss of history. The business has effectively erased the real timeline of when individual store records were last modified. This makes it impossible to know when a store’s name was last changed or its details were updated, which is valuable operational information.

While this event erased the past, another clue reveals a different problem: a digital graveyard of information the business forgot to bury.

——————————————————————————–

2.0 The Case of the Expired Information: A Data Freshness Anomaly

2.1 The Anomaly: A Database Full of Expired Cards

Our next clue is found in the customer payment information, specifically the credit card records the bike shop has on file. The numbers here tell a very strange story.

• Total Records: 19,118 credit cards on file.

• Most Common Expiration Year: 2007 (appeared 4,832 times).

• Second Most Common Expiration Year: 2006 (appeared 4,807 times).

This is a significant anomaly. Imagine a business operating today that is holding on to nearly 10,000 customer credit cards that expired almost two decades ago. This data is not just old; it’s useless for processing payments and raises serious questions about why it’s being kept.

2.2 What This Anomaly Signals

This anomaly points directly to severe issues with data freshness and the lack of a data retention policy. A healthy business regularly cleans out old, irrelevant information.

This isn’t just about messy data; it signals a potential business risk. Storing thousands of pieces of outdated financial information is inefficient and could pose a security liability. It also makes any analysis of customer purchasing power completely unreliable. The business has failed to purge stale data, making its customer database a digital graveyard of expired information.

This mountain of expired data shows the danger of keeping what’s useless. But an even greater danger lies in what’s not there at all—the ghosts in the data.

——————————————————————————–

3.0 The Case of the Missing Pieces: Anomalies of Incompleteness

3.1 Uncovering the Gaps

Sometimes, an anomaly isn’t about what’s in the data, but what’s missing. Our bike shop’s records are full of these gaps, creating major blind spots in their business operations.

1. Missing Sales Story In a table containing 31,465 sales orders, the Status column only contains a single value: “5”. This implies the system only retains records that have reached a final, complete state, or that other statuses like “pending,” “shipped,” or “canceled” are not recorded in this table. The story of the sale is missing its beginning and middle.

2. Missing Paper Trail In that same sales table, the PurchaseOrderNumber column is missing (NULL) for 27,659 out of 31,465 orders. This breaks the connection between a customer’s order and the internal purchase order. This is a significant data gap if external purchase orders were expected for these sales, making it incredibly difficult to trace orders.

3. Missing Costs In the SalesTerritory table, key financial columns like CostLastYear and CostYTD (Cost Year-to-Date) are all “0.00”. This suggests that costs are likely tracked completely outside of this relational structure, creating a data silo. It’s impossible to calculate regional profitability accurately with the data on hand.

3.2 What These Anomalies Signal

The common theme across these examples is incomplete business processes and a lack of data completeness. The bike shop cannot analyze what it doesn’t record.

These informational gaps make it extremely difficult to get a full picture of the business. Managers can’t properly track sales performance from start to finish, accountants struggle to trace order histories, and executives can’t understand which sales regions are actually profitable.

These different clues—the impossible update, the old information, and the missing pieces—all tell a story about the business itself.

——————————————————————————–

4.0 Conclusion: What Data Anomalies Teach Us

Data anomalies are far more than just technical errors or messy spreadsheets. They are valuable clues that reveal deep, underlying problems with a business’s day-to-day processes, its technology systems, and its overall data management strategy. By spotting these clues, we can identify areas where a business can improve.

Here is a summary of our investigation:

Anomaly TypeBike Shop ExampleWhat It Signals (The Business Impact)
SynchronizationAll 701 store records were “modified” at the exact same second.A past data migration erased the true modification history, blinding the business to operational changes.
Data FreshnessNearly 10,000 credit cards on file expired almost two decades ago.No data retention policy exists, creating business risk and making customer analysis unreliable.
IncompletenessMissing order statuses, purchase order numbers, and territory costs.Core business processes are not recorded, creating critical blind spots in sales, tracking, and profitability analysis.

Learning to spot anomalies is a crucial first step toward data literacy. It transforms you from a reader of reports into a data detective, capable of finding the hidden story in the numbers and using those clues to build a smarter business.

Contemporary Debates in Sociopolitical and Scientific Terminology

A Briefing on Contemporary Debates in Sociopolitical and Scientific Terminology

Executive Summary

This post synthesizes analysis on two distinct but parallel terminological debates: the evolution and contestation of the term “woke” in sociopolitical discourse, and the long-standing scientific controversy surrounding the use of “entropy” in information theory.

The term “woke,” originating in African-American English to signify an awareness of racial prejudice, has expanded to encompass a broad range of progressive social justice issues. In recent years, it has become a focal point of the culture wars, co-opted by right-wing and centrist critics globally as a pejorative to disparage movements they deem performative, superficial, or intolerant. Within leftist thought, “wokeism” and identity politics are subjects of intense internal critique. Key arguments center on the concept of “elite capture,” where a professional-managerial class co-opts social justice for its own ends, and the fundamental tension between a focus on class-based universalism and identity-based particularism.

A similar, though more technical, controversy has surrounded Claude Shannon’s concept of “entropy” in information theory since the 1940s. A substantial body of evidence and expert opinion from physicists and thermodynamicists argues that Shannon’s use of the term is a misnomer with no physical relationship to thermodynamic entropy as defined by Clausius and Boltzmann. The term was adopted on the advice of John von Neumann, based on a superficial mathematical similarity and a joke that “nobody knows what entropy really is.” This conflation has been called “science’s greatest Sokal affair,” leading to decades of scientific confusion and a “bandwagon” of misapplication across numerous fields, a trend Shannon himself warned against. Proposed terminology reform, such as replacing “Shannon entropy” with “bitropy,” aims to resolve this foundational confusion.

1. The Evolution and Contestation of “Woke”

The term “woke” has undergone a rapid and contentious evolution, moving from a specific cultural signifier to a global political battleground. Its trajectory reveals key dynamics in contemporary social and political discourse.

1.1. Origins and Initial Meaning

The term is derived from African-American English (AAVE), where “woke” is used as an adjective equivalent to “awake.” Its political connotations signify a deep awareness of racial prejudice and systemic discrimination.

• Early Usage: The concept can be traced to Jamaican activist Marcus Garvey’s 1923 call to “Wake up Ethiopia! Wake up Africa!” The specific phrase “stay woke” was used by Black American folk singer Lead Belly in a 1938 recording of “Scottsboro Boys,” advising Black Americans to remain vigilant of racial threats.

• Mid-20th Century: By the 1960s, “woke” meant well-informed in a political or cultural sense. A 1962 New York Times Magazine article by William Melvin Kelley, titled “If You’re Woke You Dig It,” documented its usage. The 1971 play Garvey Lives!includes the line, “I been sleeping all my life. And now that Mr. Garvey done woke me up, I’m gon’ stay woke.”

1.2. Modern Popularization and Broadening Scope

The term entered mainstream consciousness in the 21st century, propelled by music, social media, and social justice movements.

• Music and Social Media: Singer Erykah Badu’s 2008 song “Master Teacher,” with its refrain “I stay woke,” is credited with popularizing the modern usage. The hashtag #Staywokesubsequently spread online, notably in a 2012 tweet by Badu in support of the Russian feminist group Pussy Riot.

• Black Lives Matter: The phrase was widely adopted by Black Lives Matter (BLM) activists following the 2014 shooting of Michael Brown in Ferguson to urge awareness of police abuses.

• Expanded Definition: The term’s scope broadened beyond racial injustice to encompass a wider awareness of social inequalities, including sexism and the denial of LGBTQ rights. It became shorthand for a set of progressive and leftist ideas involving identity politics, such as white privilege and reparations for slavery.

1.3. Pejorative Co-optation and Global Spread

By 2019, “woke” was increasingly used sarcastically by political opponents to disparage progressive movements and ideas. This pejorative sense, defined by The Economist as “following an intolerant and moralising ideology,” has become a central tool in global culture wars.

• United States: “Woke” is used as an insult by conservatives and some centrists. Florida Governor Ron DeSantis has built a political identity on making his state a place “where woke goes to die,” enacting policies like the “Stop WOKE Act.” Former President Donald Trump has referred to a “woke mind virus” and, in 2025, issued an executive order to prevent “Woke AI in the Federal Government” that favors diversity, equity, and inclusion (DEI).

• France: The phenomenon of le wokisme is framed by critics as an unwelcome American import incompatible with French republican values. Former education minister Jean-Michel Blanquer established an “anti-woke think tank” and linked “wokism” to right-wing conspiracy theories of “Islamo-leftism.”

• United Kingdom: The term is used pejoratively by Conservative Party politicians and right-wing media outlets like GB News, which features a segment called “Wokewatch.”

• Other Nations: The term has been deployed in political discourse in Canada (to discredit progressive policies), Australia (by leaders of both major parties), New Zealand (by former deputy PM Winston Peters), India (by Hindu nationalists against critics), and Hungary.

1.4. The “Woke Right” and “Woke Capitalism”

Recent discourse has identified two significant offshoots of the “woke” phenomenon:

• The Woke Right: A term used to describe right-wing actors appropriating the tactics associated with left-wing activism—such as “cancel culture,” language policing, and claims of group oppression—to enforce conservative beliefs.

• Woke Capitalism / Woke-washing: Coined by Ross Douthat, this term criticizes businesses that use politically progressive messaging in advertising for financial gain, often as a substitute for genuine reform. This has been associated with the meme “get woke, go broke.” Examples cited include campaigns by Nike, Pepsi, and Gillette.

2. Leftist Critiques of Identity Politics and “Wokeism”

The rise of “woke” as a political descriptor has been accompanied by a robust and multifaceted critique from within leftist, progressive, and Marxist circles. This internal debate centers on the relationship between identity, class, and the strategic goals of emancipatory politics.

2.1. The Central Debate: Class vs. Identity

A primary tension exists between advocates for a class-first universalism and those who prioritize the specific, intersecting oppressions related to identity.

• The Class-First Perspective: Proponents, such as Adolph Reed Jr. and Walter Benn Michaels (authors of “No Politics but Class Politics”), argue for a “politics of solidarity” over a “politics of identity.” This view holds that capital is the primary dynamic of oppression and that identity politics can distract from the universalist class struggle by dividing the working class. Some argue identity politics is rooted in idealism, which is incompatible with materialist Marxism.

• Critiques of Class Reductionism: This position is challenged by those who argue it overlooks forms of oppression that persist across class lines. One user pointed to the fact that “rich black women are still significantly more likely to die in childbirth than rich white women.” Another, identifying as trans, argued that the “extreme and toxic” vilification of certain minority groups requires a narrower focus, even if it is ultimately a tool of distraction used by the capitalist class.

2.2. Elite Capture and the Professional-Managerial Class (PMC)

A prominent critique argues that modern identity politics has been co-opted by a specific socioeconomic class.

• Key Texts: This critique is articulated in works like Olúfẹ́mi O. Táíwò’s “Elite Capture” and Catherine Liu’s “Virtue Hoarders: The Case Against the Professional Managerial Class.”

• The Argument: These thinkers posit that the PMC co-opts the language and goals of social justice movements, not for material change for the masses, but to consolidate its own cultural and economic capital. Catherine Liu’s broader argument is that critical theory academics have disconnected from both empirical data and Marxist political economy.

• A Sharper Critique: Adolph Reed Jr. criticizes Táíwò’s work as the “quintessence of neoliberal leftism,” arguing that it naturalizes and accepts elite capture and celebrates “performative radicalism” (like the Combahee River Collective and Black Lives Matter) while accepting its failure to produce substantive change in social relations.

2.3. Original Intent vs. “Identity Reductionism”

Several commentators distinguish between the original formulation of “identity politics” and its contemporary usage.

• The Combahee River Collective: The term “identity politics” was coined in the 1977 Combahee River Collective Statement. The original intent was materialist, viewing identity as a starting point for understanding one’s relationship to oppression and as a basis for coalition-building. It conceived of identity not as a static, essentialist category, but as a dynamic “process of becoming.”

• Contemporary Distortion: Critics argue that the current, “impossibly distorted version” of identity politics promotes “identity reductionism.” This modern form is seen as devolving into debates over who “has got the worst” and rejecting universalism in favor of an exclusive focus on particular subjectivities.

2.4. A Curated List of Critical Works

A Reddit discussion on this topic generated a comprehensive list of recommended literature, essays, and media from a leftist perspective critical of contemporary identity politics.

3. A Case Study in Terminology Confusion: Shannon “Entropy”

A decades-long debate in physics, thermodynamics, and engineering provides a compelling parallel to the semantic drift and confusion seen in sociopolitical terms. The controversy centers on Claude Shannon’s use of the word “entropy” in his foundational 1948 work, “A Mathematical Theory of Communication.”

3.1. The Central Argument: A Scientific Misnomer

The core thesis, articulated in the Journal of Human Thermodynamics and supported by numerous physicists and thermodynamicists since the 1950s, is that Shannon’s information “entropy” has “absolutely positively unequivocally NOTHING to do with” thermodynamic entropy. The conflation is described as a “farcical train of misconceptions” and “science’s greatest Sokal affair,” stemming from a coincidental similarity in the mathematical forms of the two concepts.

3.2. Dueling Origins and Definitions

The two concepts of “entropy” originate from entirely different scientific domains and describe fundamentally different phenomena.

Concept

Origin

Definition & Units

Thermodynamic Entropy

Formulated by Rudolf Clausius (1865) from the study of heat engines. Later developed by Ludwig Boltzmann and Willard Gibbs.

A physical state function related to heat transfer divided by temperature. Measured in joules per kelvin (J/K).

Shannon Entropy (H)

Developed by Claude Shannon (1948) from the study of telegraphy, signal transmission, and cryptography.

A mathematical function measuring choice, uncertainty, or information in a message. Measured in bits per symbol.

3.3. The 1940 Neumann Anecdote: Source of the Confusion

The historical record indicates that the terminological confusion was initiated by a conversation between Shannon and the mathematician John von Neumann around 1940.

• The Advice: When Shannon was deciding what to call his H function, von Neumann reportedly told him, “You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name. In the second place, and more importantly, no one knows what entropy really is, so in a debate you will always have the advantage.”

• The True Origin: The actual mathematical predecessor to Shannon’s formula was not Boltzmann’s work on thermodynamics but Ralph Hartley’s 1928 paper, “Transmission of Information,” which used logarithms to quantify signal sequences.

3.4. The “Bandwagon Effect” and a History of Warnings

Following the publication of Shannon’s 1948 paper, the idea of information “entropy” was widely and inappropriately applied to a vast array of fields outside of communications engineering, including biology, psychology, economics, and sociology.

• Shannon’s Warning: Alarmed by this trend, Shannon himself published a 1956 editorial titled “The Bandwagon,” urging restraint and warning that applying his theory to fields like psychology and economics was “not a trivial matter of translating words to a new domain” and that such work was often “a waste of time to their readers.”

• Decades of Dissent: A long line of scientists have issued similar warnings:

    ◦ Dirk ter Haar (1954): “[The] entropy introduced in information theory is not a thermodynamical quantity and that the use of the same term is rather misleading.”

    ◦ Harold Grad (1961): “The lack of imagination in terminology is confusing.”

    ◦ Kenneth Denbigh (1981): “In my view von Neumann did science a disservice!”

    ◦ Frank L. Lambert (1999): “Information ‘entropy’ … has no relevance to the evaluation of thermodynamic entropy change.”

3.5. Proposed Terminology Reform: “Bitropy”

To end the seven-decade-long confusion, the author of the source paper proposes an official terminology reform: replacing the name Shannon entropy with bitropy.

• Etymology: “Bitropy” is a portmanteau of “bit-entropy” or “bi-tropy.” It translates as the transformation (-tropy) of a choice between two (bi-) alternatives (bits) into information.

• Goal: The name change aims to permanently sever the false link to thermodynamics and “release a large supply of manpower to work on the exciting and important problems which need investigation,” as editor Peter Elias argued in a 1958 parody of the bandwagon effect.

:A Personal Health Journey: Stroke Recovery and Weight Loss

: “A Personal Health Journey: Stroke Recovery and Weight Loss”

Source: Excerpts from “A Personal Health Journey: Stroke Recovery and Weight Loss” by Ira Warren Whiteside.

Date: (Implied, covering the period from 2014 to 2025)

Prepared For: (Intended audience, e.g., researchers, health professionals, general public interested in stroke recovery)

Subject: A personal account of stroke recovery and significant weight loss, detailing the timeline of events, symptoms experienced, and the author’s observations regarding the recovery process.

Executive Summary:

This document summarizes excerpts from Ira Warren Whiteside’s personal narrative of his health journey following an ischemic brainstem stroke in 2014. The account highlights a period of significant weight loss (155 pounds overall, including 80 pounds in one year starting in 2021) alongside the progression and eventual improvement of post-stroke symptoms. The author details the impact of dietary changes (cutting out sugar, seed oil, ultra-processed food, and alcohol) on his symptoms and mentions discovering the Brunnstrom stages of mobility recovery. A notable and seemingly counter-intuitive observation is the worsening of some neurological symptoms concurrent with weight loss, which the author links to a phenomenon observed in bariatric patients and supported by scientific studies, suggesting fat loss from nerves themselves. The narrative concludes with the author feeling recovery is finally occurring in 2025.

Key Themes and Most Important Ideas/Facts:

  1. Initial Stroke and Recovery (2014): The author experienced an ischemic brainstem stroke in 2014. He notes that he “recovered and [he] Still Worked and flew,” indicating a level of functional recovery in the initial period.
  2. Significant Weight Loss (2021-2022 & Overall): A major focus of the narrative is substantial weight loss. The author “lost 80 pounds in one year stared at 300 pounds” starting in 2021. Overall, he reports losing “155 pounds.”
  3. Dietary Changes and Symptom Progression: The author made significant dietary changes, “Cut out sugar and seed oil and all Ultra processed food and all alcohol.” He notes that concurrent with these changes and weight loss, his “Slur got worse.”
  4. Detailed Neurological Symptoms (2023): The account provides a list of neurological symptoms experienced, particularly intensifying in 2023, which the author describes as “Third year very bad.” These include:
  • “Nueral fajtque tiredness exhaustion” (repeated for emphasis).
  • “Pheneric. nerve breathing nerve referrred pain in shoulder.”
  • “Foot Drop got worse.”
  • “Elbow got worse.”
  • “Hand got worse.”
  1. Discovery of Brunnstrom Stages: The author mentions discovering the “Brunnstrom stages of mobility recovery,” indicating an engagement with understanding the process of neurological recovery.
  2. Unconventional Observation: Symptom Worsening and Nerve Fat Loss: A critical and perhaps surprising element of the narrative is the observed worsening of some neurological symptoms alongside significant weight loss. The author posits a connection, stating that the weight loss included “fat from [his] nerve i in leg and throat and arm.” He claims this phenomenon has happened to “many people bariatric patients” and is “Well documented. by scientific studies.” This suggests a potential link between systemic fat reduction and neurological function, particularly concerning nerve fat.
  3. Turning Point and Improvement (2025): The narrative concludes on a hopeful note, with the author stating that he is “Finally getting better. It makes sense.” This suggests a period of recovery and improvement is underway in 2025 after the difficult period described in 2023.

Important Quotes:

  • “2014 brainstem lStroke Ischemic I recovered and I Still Worked and flew”
  • “2021 lost 80 pounds in one year stared at 300 pounds”
  • “Cut out sugar and seed oil and all Ultra processed food and all alcohol”
  • “Slur got worse”
  • “Third year very bad”
  • “Overall one and lost 155 pounds”
  • “Including fat from my nerve i in leg and throat and arm”
  • “This happened too, many people bariatric patients Well documented. by scientific studies”
  • “2025 Finally getting better. It makes sense.”

Limitations:

It is important to note that this is a personal account and, as the author states, “My personal experience I’m not a doctor. This is not health advice only my knowledge and experience.” The narrative provides anecdotal evidence and personal observations. While the author references scientific studies regarding nerve fat loss in bariatric patients, the specifics of these studies are not included in the provided excerpts.

Further Considerations:

This account raises interesting questions about the complex interplay between metabolic changes (specifically significant weight loss) and neurological recovery after stroke. The observation regarding potential fat loss from nerves and its possible link to symptom fluctuation warrants further investigation and comparison with clinical data and research. The narrative could be a valuable starting point for discussions between patients and healthcare providers regarding the multifaceted nature of stroke recovery.

Researching RAG

This briefing document summarizes the main themes and important ideas presented in the provided sources regarding Retrieval Augmented Generation (RAG) systems. The sources include a practical tutorial on building a RAG application using LangChain, a video course transcript explaining RAG fundamentals and advanced techniques, a GitHub repository showcasing various RAG techniques, an academic survey paper on RAG, and a forward-looking article discussing future trends.

1. Core Concepts and Workflow of RAG:

All sources agree on the fundamental workflow of RAG:

  • Indexing: External data is processed, chunked, and transformed into a searchable format, often using embeddings and stored in a vector store. This allows for efficient retrieval of relevant context based on semantic similarity.
  • The LangChain tutorial demonstrates this by splitting a web page into chunks and embedding them into an InMemoryVectorStore.
  • Lance Martin’s course emphasizes the process of taking external documents, splitting them due to embedding model context window limitations, and creating numerical representations (embeddings or sparse vectors) for efficient search. He states, “The intuition here is that we take documents and we typically split them because embedding models actually have limited context windows… documents are split and each document is compressed into a vector and that Vector captures a semantic meaning of the document itself.”
  • The arXiv survey notes, “In the Indexing phase, documents will be processed, segmented, and transformed into Embeddings to be stored in a vector database. The quality of index construction determines whether the correct context can be obtained in the retrieval phase.” It also discusses different chunking strategies like fixed token length, recursive splits, sliding windows, and Small2Big.
  • Retrieval: Given a user query, the vector store is searched to retrieve the most relevant document chunks based on similarity (e.g., cosine similarity).
  • The LangChain tutorial showcases the similarity_search function of the vector store.
  • Lance Martin explains this as embedding the user’s question in the same high-dimensional space as the documents and performing a “local neighborhood search” to find semantically similar documents. He uses a 3D toy example to illustrate how “documents in similar locations in space contain similar semantic information.” The ‘k’ parameter determines the number of retrieved documents.
  • Generation: The retrieved document chunks are passed to a Large Language Model (LLM) along with the original user query. The LLM then generates an answer grounded in the provided context.
  • The LangChain tutorial shows how the generate function joins the page_content of the retrieved documents and uses a prompt to instruct the LLM to answer based on this context.
  • Lance Martin highlights that retrieved documents are “stuffed” into the LLM’s context window using a prompt template with placeholders for context and question.

2. Advanced RAG Techniques and Query Enhancement:

Several sources delve into advanced techniques to improve the performance and robustness of RAG systems:

  • Query Translation/Enhancement: Modifying the user’s question to make it better suited for retrieval. This includes techniques like:
  • Multi-Query: Generating multiple variations of the original query from different perspectives to increase the likelihood of retrieving relevant documents. Lance Martin explains this as “this kind of more shotgun approach of taking a question Fanning it out into a few different perspectives May improve and increase the reliability of retrieval.”
  • Step-Back Prompting: Asking a more abstract or general question to retrieve broader contextual information. Lance Martin describes this as “stepback prompting kind of takes the the the opposite approach where it tries to ask a more abstract question.”
  • Hypothetical Document Embeddings (HyDE): Generating a hypothetical answer based on the query and embedding that answer to perform retrieval, aiming to capture semantic relevance beyond keyword matching. Lance Martin explains this as generating “a hypothetical document that would answer the query” and using its embedding for retrieval.
  • The NirDiamant/RAG_Techniques repository lists “Enhancing queries through various transformations” and “Using hypothetical questions for better retrieval” as query enhancement techniques.
  • Routing: Directing the query to the most appropriate data source among multiple options (e.g., vector store, relational database, web search). Lance Martin outlines both “logical routing” (using the LLM to reason about the best source) and “semantic routing” (embedding the query and routing based on similarity to prompts associated with different sources).
  • Query Construction for Metadata Filtering: Transforming natural language queries into structured queries that can leverage metadata filters in vector stores (e.g., filtering by date or source). Lance Martin highlights this as a way to move “from an unstructured input to a structured query object out following an arbitrary schema that you provide.”
  • Indexing Optimization: Techniques beyond basic chunking, such as:
  • Multi-Representation Indexing: Creating multiple representations of documents (e.g., summaries and full text) and indexing them separately for more effective retrieval. Lance Martin describes this as indexing a “summary of each of those” documents and using a MultiVectorRetriever to link summaries to full documents.
  • Hierarchical Indexing (Raptor): Building a hierarchical index of document summaries to handle questions requiring information across different levels of abstraction. Lance Martin explains this as clustering documents, summarizing clusters recursively, and indexing all levels together to provide “better semantic coverage across like the abstraction hierarchy of question types.”
  • Contextual Chunk Headers: Adding contextual information to document chunks to provide more context during retrieval. (Mentioned in NirDiamant/RAG_Techniques).
  • Proposition Chunking: Breaking text into meaningful propositions for more granular retrieval. (Mentioned in NirDiamant/RAG_Techniques).
  • Reranking and Filtering: Techniques to refine the initial set of retrieved documents by relevance or other criteria.
  • Iterative RAG (Active RAG): Allowing the LLM to decide when and where to retrieve, potentially performing multiple rounds of retrieval and generation based on the context and intermediate results. Lance Martin introduces LangGraph as a tool for building “state machines” for active RAG, where the LLM chooses between different steps like retrieval, grading, and web search based on defined transitions. He showcases Corrective RAG (CAG) as an example. The arXiv survey also describes “Iterative retrieval” and “Adaptive retrieval” as key RAG augmentation processes.
  • Evaluation: Assessing the quality of RAG systems using various metrics, including accuracy, recall, precision, noise robustness, negative rejection, information integration, and counterfactual robustness. The arXiv survey notes that “traditional measures… do not yet represent a mature or standardized approach for quantifying RAG evaluation aspects.” It mentions metrics like EM, Recall, Precision, BLEU, and ROUGE. The NirDiamant/RAG_Techniques repository includes “Comprehensive RAG system evaluation” as a category.

3. The Debate on RAG vs. Long Context LLMs:

Lance Martin addresses the question of whether increasing context window sizes in LLMs will make RAG obsolete. He presents an analysis showing that even with a 120,000 token context window in GPT-4, retrieval accuracy for multiple “needles” (facts) within the context decreases as the number of needles increases, and reasoning on top of retrieved information also becomes more challenging. He concludes that “you shouldn’t necessarily assume that you’re going to get high quality retrieval from these long contact LMS for numerous reasons.” While acknowledging that long context LLMs are improving, he argues that RAG is not dead but will evolve.

4. Future Trends in RAG (2025 and Beyond):

The Chitika article and insights from other sources point to several future trends in RAG:

  • Mitigating Bias: Addressing the risk of RAG systems amplifying biases present in the underlying datasets. The Chitika article poses this as a key challenge for 2025.
  • Focus on Document-Level Retrieval: Instead of precise chunk retrieval, aiming to retrieve relevant full documents and leveraging the LLM’s long context to process the entire document. Lance Martin suggests that “it still probably makes sense to ENC to you know store documents independently but just simply aim to retrieve full documents rather than worrying about these idiosyncratic parameters like like chunk size.” Techniques like multi-representation indexing support this trend.
  • Increased Sophistication in RAG Flows (Flow Engineering): Moving beyond linear retrieval-generation pipelines to more complex, adaptive, and self-reflective flows using tools like LangGraph. This involves incorporating evaluation steps, feedback loops, and dynamic retrieval strategies. Lance Martin emphasizes “flow engineering and thinking through the actual like workflow that you want and then implementing it.”
  • Integration with Knowledge Graphs: Combining RAG with structured knowledge graphs for more informed retrieval and reasoning. (Mentioned in NirDiamant/RAG_Techniques and the arXiv survey).
  • Active Evaluation and Correction: Implementing mechanisms to evaluate the relevance and faithfulness of retrieved documents and generated answers during the inference process, with the ability to trigger re-retrieval or refinement steps if needed. Corrective RAG (CAG) is an example of this trend.
  • Personalized and Multi-Modal RAG: Tailoring RAG systems to individual user needs and expanding RAG to handle diverse data types beyond text. (Mentioned in the arXiv survey and NirDiamant/RAG_Techniques).
  • Bridging the Gap Between Retrievers and LLMs: Research focusing on aligning the objectives and preferences of retrieval models with those of LLMs to ensure the retrieved context is truly helpful for generation. (Mentioned in the arXiv survey).

In conclusion, the sources paint a picture of RAG as a dynamic and evolving field. While long context LLMs present new possibilities, RAG remains a crucial paradigm for grounding LLM responses in external knowledge, particularly when dealing with large, private, or frequently updated datasets. The future of RAG lies in developing more sophisticated and adaptive techniques that move beyond simple retrieval and generation to incorporate reasoning, evaluation, and iterative refinement.
