Questions to Ask

When someone presents evidence, run it through these filters: Who produced it? Funded by a company selling the product? Suspicious. How was it gathered? Small sample? Self-reported? Uncontrolled? Weak.

The fifth question: what does the broader evidence say? A single study can find almost anything by chance. What matters is the pattern across many studies. If 50 studies say one thing and one says the opposite, the outlier needs extraordinary scrutiny, not headlines.
