📖 Neuro Nook Recap: October 2025-May Contain Lies

📘May Contain Lies: How Stories, Statistics, and Studies Exploit Our Biases—And What We Can Do About It by Alex Edmans

What’s This Book About❓

This book is a practical guide to help you think smarter, sharper, and more critically–on topics… BUT knowledge is only half the battle. Having knowledge isn’t enough: we need to know when to use it and how to use it.

“It’s impossible to overcome our biases in every situation and correctly evaluate every piece of information; the range of ways we can be deceived may seem overwhelming. Our goal is not to become perfect, only better.”

No calculators needed. No math required. Just your curiosity to dive into this book recap and to explore additional resources. I hope this is helpful to you in some way!

What I’m trying to highlight is the importance of being discerning.

We want to have healthy skepticism, but we want to have the same healthy skepticism to something that we do like as something that we don’t.

- Dr. Alex Edmans, Ph.D.

💭 Reflection Questions for Real Life Integration

• When was the last time you accepted a claim without checking the source or evidence? How might you have approached it differently?

• Which of your own biases do you notice influencing how you interpret information?

• How often do you seek out opposing viewpoints before forming an opinion? What barriers stop you from doing so?

• Think of a recent news story or social media post—what steps could you take to verify its accuracy?

• How can you turn critical thinking into a habit in your daily life, not just for big decisions but for small ones too?

📘 Introduction

In a world overflowing with misinformation, this book shows how false or misleading information affects our daily lives—how we vote, learn, make health decisions, or handle money. Even sources we consider reliable—government reports, consultancies, academic papers—can carry biases, and blindly following advice can have serious consequences.

The book emphasizes that knowledge alone isn’t enough: we need to know when and how to use it. Critical thinking becomes our guide in navigating a post-truth world, helping us distinguish fact from fiction and make wiser decisions. Social media has amplified the spread of false information, making it more important than ever to question what we read and hear—even if it comes from a trusted authority.

By recognizing our own biases and remaining open to other perspectives, we can build understanding across divides, interpret evidence more accurately, and spread knowledge rather than misinformation. Ultimately, this approach supports healthier lives, smarter decisions, stronger communities, and a more informed society.

“Misinformation surrounds us and affects our everyday lives-how we vote, learn a skill our improve our health…Blindly following advice, you could find yourself sicker, poorer and unemployed.

🪜The Ladder of Misinference

The author introduces a ladder of misinference which categorizes misinformation into 4 steps: Statement → Fact → Data → Evidence → Proof. You can read Alex’s blog for additional information on the 4 steps and a summary recap of each.

📖 Part I Summary: The Biases

Confirmation Bias

• We interpret facts in ways that support our existing beliefs, often ignoring alternative explanations.

• Belief polarization occurs even when two people see the same data—they interpret it differently based on prior opinions.

• Biased search and interpretation reinforce existing views: we tend to find and see only the evidence that supports us, even when more information is available.

• People respond to opposing views as if they’re being chased by a wild animal!

• Strong emotional responses (amygdala activation) can override rational thinking (prefrontal cortex), making it hard to process opposing views objectively.

• Motivated reasoning feels good: dismissing evidence we dislike releases dopamine.

Black-and-White Thinking

• Simplified rules are attractive but can mislead us when applied rigidly.

• Many things are moderate (beneficial up to a point), granular (different forms with varying effects), or marbled (containing both good and bad elements).

• We are drawn to claims that are both appealing and extreme, which can reinforce oversimplified thinking.

---

📖 Part II: The Problems

A Statement is Not a Fact

• Statements may be inaccurate, misrepresented, or taken out of context.

• Even references, footnotes, or quotes can be selective or misleading.

• Some statements are completely fabricated, yet extreme or appealing claims are often believed without verification.

• The reliability of a statement lies on a spectrum; it’s important to check for alternative explanations and supporting evidence.

Since 2009, PolitiFact has named a ‘Lie of the Year.’ Want to see the full list from 2009–2024? You may or may not be surprised at who shows up the most.

Hint: My home state of Ohio was part of the ‘2024 Lie of the Year’—anything come to mind for you?

A Fact is Not Data

• Individual facts or anecdotes don’t constitute reliable evidence.

• Narrative fallacies make stories compelling, even if false, and can amplify biases.

• “It worked for me” doesn’t mean it will work for you—context matters.

Data is Not Evidence

• Statistical significance doesn’t prove causation; correlations can be spurious, meaning the relationship is due to randomness.

• Data mining can create misleading patterns if studies aren’t carefully designed or robustly tested.

• Extrapolating from descriptive data to broad predictions is risky.

What do “Google searches for ‘Taylor Swift’ and fossil fuel use in the British Virgin Islands” and “Popularity of the first name ‘Blanca’ and number of robberies in Texas” have in common?

They are examples of spurious correlations—two completely unrelated events that appear to be connected by chance or an unseen factor, but have no real causal relationship.

This is that buzzword phrase that has been going around lately and may sound familiar from a statistics class, “Correlation is NOT causation.”

Tyler Vigen has a website that lists THOUSANDS of the most bizarre spurious correlations… You may be entertained for at least a few minutes while learning a few new, bizarre things along the way!

When Data Becomes Evidence

• Randomized controlled trials are the gold standard because random assignment allows causal inference.

• Evidence is context-dependent and not universal; its value depends on validity and applicability.

• Common sense helps interpret evidence in real-world situations, considering trade-offs and unintended consequences.

Key Takeaways

• Always question the source, context, and methodology of information.

• Even well-meaning research can mislead if misinterpreted or taken out of context.

• Critical thinking and skepticism are essential to separate useful evidence from misleading claims

Part III: The Solutions

As Individuals:

• Make better decisions by actively seeking both sides of an argument.

Check out Tangle, a newsletter that offers a 360-degree view of the news. I started reading it to stay informed on issues from multiple perspectives. It’s free to explore, and I’m sharing it as a resource—no incentives or affiliations, just a reliable, fact-based source that looks at more than one side.

• Pause before sharing, reacting, or posting online; prioritize informing over popularity.

• Verify sources: check peer-reviewed studies, systematic reviews, author credentials, and potential biases.

• Remember key rules: correlation is not causation, and evidence is not proof.

• Critical thinking guides decisions, even if perfection is impossible.

“Now more than ever, the person the street plays an important role in combating or amplifying misinformation.”

---

In Organizations:

• Promote cognitive diversity: different experiences, backgrounds, and problem-solving styles.

• Encourage social diversity: people from various social groups take dissenting opinions more seriously.

• Foster scientific culture: share bold ideas, seek feedback, and revise based on criticism.

• Avoid herd mentality by valuing independent thinking and structured brainstorming.

---

In Societies:

• Teach statistical literacy and skepticism from a young age—distinguishing facts, data, evidence, and proof.

• Encourage curiosity through science, arts, and accessible educational resources.

• Focus public messaging on evidence, not identity, to counter cultural biases.

• Ensure transparency: studies, data, and academic work should be freely accessible for verification.

• Shift incentives away from attention or profit toward accuracy and critical thinking.

“Understanding that correlation does NOT imply causation is as simple as being aware of alternative explanations, just as kids whodunit brainteasers have multiple potential culprits.”

📝 Brain Health Rx from May Contain Lies

“Practice critical thinking daily. Treat every post, article, or claim as a mental workout to separate truth from noise.”

✨ Final Thought

Awareness of your own biases is the first step toward thinking smarter. No source is perfect, and no story is neutral—being curious and cautious helps you navigate a world full of information.

---

Your Takeaway Action

Before sharing or believing any claim, pause and ask:

• What’s the evidence?

• Could there be another explanation?

• Who benefits if I believe this? (And other questions you may come up with.)

Make this your daily habit to sharpen your critical thinking.

💬 Closing Takeaways from the Hosts

Heather: “Most people do not listen with the intent to understand; they listen with the intent to reply.” - Stephen Covey

Krystal: To paraphrase the conclusion of the book…
“Evidence still has shortcomings. Evidence can NEVER tell you what to do; it can only make us aware of the possible upsides and downsides to our actions… Most choices we make are multidimensional. Evidence still can’t dictate the only action we should take…What matters isn’t whether the decision is right in general but whether it’s right for us.”
