Excellent post - it makes me wish that the system gave out a limited number of super-votes, like 1 for every 20 karma, so that I could vote this up twice.

I hope you don't mind, but I did a quick edit to insert "a choice of" before "two drugs to test", because that wasn't clear on my first reading. (Feel free to revert if you prefer your original wording.) Also edited the self-deception tag to self_deception per previous standard.
