Advertising Works

There was a programme on TV tonight (Professor Regan's Pharmacy), about the science behind homeopathy. Rugby players took a pain relief tablet that they thought was branded and then put one hand in ice water. Then (I'm guessing a while later) they took a different pain relief tablet - one they thought was own label - and put their other hand in ice water. They lasted about 8 minutes with what they thought was a branded pain relief, and less than half that with what they thought was an own label version. Turns out it was actually another branded product, same dose, leading to the conclusion that "Branding on painkillers seems to give additional pain relief." The advertising, packaging and brand name have a placebo effect, which when absent actually decreases the perceived performance of the product. A nice simple example of advertising effectiveness.
