How to unravel science

“The first principle is that you must not fool yourself,
and you are the easiest person to fool.”

Richard Feynman.

Headlines in newspaper, articles in magazines and programs on television offer new health guidelines every week and they often contradict each other.

You know the kinds of stories I am talking about. First garlic protects against heart disease, then suddenly it doesn’t. You read coffee is supposed to be full of antioxidants, then you see another story that says it causes cancer. It is all very confusing. It makes you wonder what information to trust and what to dismiss.

Tom Naughton did a lecture on this at the Low Carb Cruise:

Ben Goldacre also did a presentation on this topic at TED:

In summary:

  • If you really want to know whether you can trust the research you read about, you need to know how the research was conducted.
  • Don’t be intimidated by science. A bit of critical thinking is all you need to determine if the information you are given is worth paying attention to. Tom Naughton’s lecture offers tips on this.
  • Know the difference between an observational study and a clinical study. Observational studies try to find correlations between events and outcomes. They are useful for developing hypotheses, but are not conclusive proof of anything.
  • Be aware that most health coverage in popular media is based on findings from observational studies.

More than ever, it’s critical to think critically. Bad information travels fast on the internet. Guard yourself by learning how to sniff out the good stuff from the bad.
