I didn't choose that example by accident ;).

If I didn't know better, "salicylic acid" sounds like one of those chemicals that scientists keep putting in our food as part of their ongoing efforts to KILL ALL OF US, while "willow bark" sounds oh-so-natural and wholesome and makes me think of green meadows and chirping birds. So despite the fact that we know aspirin is a lot more effective than willow bark, I'd still feel a lot more comfortable eating willow bark. If I didn't know better.

Basically, evidence-based medicine faces a big marketing problem, thanks to the "evidence" part.
