I'm one who would probably benefit from this sort of radical treatment, but I'm way too chicken.
Along the same lines as Paul Buchheit's "Serendipity Finds You" piece, except Rejection Therapy is the actual prescription to beating (what he calls) ego-fear. Fascinating.
social anxiety is a staggering problem. I've read that 1 in 4 adults have it (citation needed, too lazy to look it up).
If this gives people hope, an alternative to gobbling prescription drugs, then all the power to it.
