🧪 Science & Critical Thinking

Curated links and references for identifying outdated or unsupported scientific claims.

Use this page when a headline, blog, or video makes a “science-y” claim that feels too neat, too absolute, or too good to be true.

📌 Sam’s Tips

Start with the date. Old studies often get recycled as “new.” Fresh, high-quality evidence matters.

Prefer summaries over single studies. Systematic reviews beat one small study — or a headline based on one — every time.

Look for the data, not just the claim. If a source won’t show methods, sample size, or links to studies, treat it as unproven.

Extraordinary claims need extraordinary evidence. Big promises require strong, converging proof from multiple independent sources.

Be cautious with miracle language. “Cure,” “detox,” “secret,” or “they don’t want you to know” are classic red flags.

🧪 Quick example

A headline claims: “New study proves that eating dark chocolate every day triples your memory.”

Stop — “proves” is a major red flag in science reporting.
Investigate — searching for the study reveals it was small (18 participants) and used self-reported memory tests.
Find better coverage — reputable science outlets note that the study only found a short-term correlation, not a proven cognitive boost.
Trace — the paper’s authors state clear limitations: no long-term follow-up, no control for diet or sleep, and results not yet replicated.

Conclusion

This claim fails verification. The study is too small, unreplicated, and limited to support broad conclusions about memory improvement.

Why

• Small, underpowered studies rarely justify sweeping claims.
• Self-reported outcomes introduce bias and variability.
• Headlines often convert preliminary findings into exaggerated promises.
• Verification collapses because the claim lacks replication, robust data, and a plausible biological mechanism.

Bottom line:
If a study sounds impressive but is small, unreplicated, or over-summarized in headlines, treat the claim cautiously until stronger evidence emerges.
