My experience with people in the community is almost entirely talking with people in person - I've read very little of the blog, so I'm used to more one on one conversation that is customized than the blog conventions. I was wrong that this article would be something the general LW crowd would like, so I'm now being more cautious about other assumptions about shared perspectives.

I can certainly see people's objections about perspectives being shared without evidence. Unfortunately my personal evidence mostly comes from working with clients, which is a small sample and data I cannot share. My clients almost all improve over time, and I am taking stats, but not stats I can share, and the stats I'm taking are about general improvement and don't isolate progress resulting from each of the specific techniques I use. I would love more data myself, and I think I'm doing a much better job of gathering data personally than any psych professional I've ever worked with as a client, although I'd still like to do better.
