Become a patient scientist.
Science Is a Way of Thinking
Medicine works best when patients don't have to choose between blindly trusting everything they're told and distrusting everything they're told. At EvolveMD, we want you to understand not only what we're recommending, but why.
Curiosity asks the question. Evidence helps us test the answer. Compassion reminds us why the answer matters.
What kind of evidence is this?
Anecdote, laboratory finding, observational study, randomized trial, systematic review, and guideline are not interchangeable. Ask what the evidence can actually establish.
Association does not equal causation
Two things moving together does not prove that one caused the other. Look for confounding variables, timing, dose-response patterns, and alternative explanations.
Absolute vs. relative risk
A large relative change can represent a small absolute difference. Ask for the actual event rates so you can understand the size of the benefit or harm.
Statistical vs. clinical significance
A result can be statistically detectable without being large enough to matter meaningfully to patients. Ask how big the effect is, not only whether the p-value crossed a threshold.
Single study vs. body of evidence
One study can be interesting without settling a question. Replication, consistency, study quality, and the total evidence matter more than a headline.
What would change our minds?
Good scientific reasoning is falsifiable. We should be able to say what evidence would make us revise our current conclusion.

Interrogate the claim
Who is making it? What exactly are they claiming? Is the claim specific enough to test?
Interrogate the evidence
Look for independent confirmation, appropriate comparison groups, plausible alternatives, effect size, and whether the methods match the conclusion.
Interrogate yourself
Confirmation bias applies to all of us. Ask whether you are applying the same standard of evidence to claims you like and claims you dislike.
Read past the headline
Follow the chain from paper → press release → newswire → internet → television/social media. Details and uncertainty are often lost at each step.
Understand incentives
Funding, financial relationships, ideology, attention, and publication incentives do not automatically invalidate evidence, but they are relevant context.
Ask what would change your mind
If no possible evidence could change a conclusion, the claim is no longer being treated scientifically.
