How to Verify Truth in the Internet Era: A Baker's Dozen Flags for Reliable Information

In this talk, a scientist-educator discusses how to decide what is true when searching the internet. He introduces a practical framework, a baker's dozen of cautions, to help identify information that is trustworthy and sources that should be treated with suspicion.

Key ideas include prioritizing credible domains like .edu, recognizing vested interests, checking for original sources, and distinguishing opinion from objective data. He notes that large language models can be wrong and that links to sources matter. The talk uses examples from the tobacco industry, vaccine debates, and conspiracy claims to illustrate yellow flags and red flags that guide careful verification.

Introduction

In this talk, a scientist-educator reflects on the challenge of determining truth online and presents a practical framework for evaluating information in the era of AI.

Why truth is hard on the internet

The speaker emphasizes that the internet is filled with bias, noise, and endless opinions. Even when we think we know something, AI language models may misrepresent or misunderstand because they generate text based on patterns rather than understanding. He argues that objective truth matters and advocates for verification, bias checks, and seeking credible sources.

Trustworthy sources and flags

A core idea is to treat information with caution based on its source. He discusses flags signaling caution, including domain credibility (like .edu), vested financial interests, and content that presents opinions as information.

The Baker's Dozen Cautions

He outlines a dozen cautions, which span yellow flags and red flags. The cautions highlight how source selection, expertise, context, and scientific replication affect trustworthiness. The list includes examples where industry defense of practices and headlines about frontier science require extra scrutiny.

1. Yellow flag: content from sources with financial stakes or industry defenders
2. Yellow flag: discounting evidence due to industry funding or vested interests
3. Yellow flag: podcasts lacking sufficient expertise to probe and critique
4. Yellow flag: opinions handed to you as information that should shape your views
5. Yellow flag: content that has been reposted or lifted from its original source and may lack context
6. Yellow flag: frontier science with little replication or verification
7. Red flag: results that conflict with other research or are cherry-picked
8. Red flag: conspiracy narratives that rely on a cover up or withholding data
9. Red flag: claims that mainstream thinking is false and the speaker alone has the truth
10. Red flag: indicting an entire demographic or industry as monolithic
11. Red flag: sensational claims that would render entire industries obsolete
12. Red flag: extraordinary claims such as alien contact without rigorous verification

Conspiracy, mainstream thinking, and credibility

The talk argues that while conspiracies exist, most credible information rests on robust evidence and peer-reviewed consensus. Mainstream is not the enemy; credible science builds on consensus and replication.

Practical guidance for everyday information literacy

Viewers are urged to base opinions on objective truth found through original sources, verify information independently, and be wary of emotionally resonant but unverified claims. The overarching message is to cultivate critical thinking and responsible use of information tools.

Closing thoughts

In an information-saturated world, the goal is to elevate trust in credible science by applying a disciplined approach to evaluating sources, verifying claims, and maintaining intellectual humility.
