Mike, there is an interesting article on placebos vs. antidepressants in this week's issue of newsweek:

The placebo effect is indeed very strong.
Say you have a depression trial. After 6 weeks, 40% of the placebo group are better and 55% of the medication group are better. You had better have enough numbers to ensure statistical power. So clinical researchers do spend time trying to "combat" placebo effect, by designing trials to not have the folks that are likey to get better very easily and quickly. |
