When science becomes an extension of marketing...

Physician and epidemiologist Ben Goldacre gives a great TED Talk on battling bogus health science, in the media and in science itself:

Sometimes companies stack the odds in their favor by using improperly designed studies. A favorite tactic is to compare the new drug to a placebo when there's already a good alternative treatment available. Another ploy is to compare a correct dose of the experimental drug to the wrong dose of the control drug--so that the patients in the control group are under-treated or plagued by side effects.

However, Goldacre says, in general industry sponsored trials are better designed than independently sponsored trials. (He doesn't explain why that might be.)

The real problem is that the industry simply hides negative results. We know this is going on because pharmaceutical companies have been caught doing it, and because statistical analysis of the range of studies that do get published points to massive as-yet-undiscovered data suppression by industry.

  1. I suddenly remembered a friend who was a former business consultant turned salesman selling me an item, which I find ridiculously expensive. He talked about physics and theories. He was convincing but I don't think a simple object could do as much as he explained to me.
