Tyler Cowen points to an interview with Justin Wolfers on interdisciplinary work. The money quote:

So [psychologists] have a different method of trying to isolate causation. I am certain that we have an enormous amount to learn from them. But I am curious why we have not been able to convince them of the importance of careful analysis of observational data.

At the recent economics conference I had an opportunity to hear from a very bright young psychologist. The data measures that psychologist had were fascinating but the regression analysis was horrid.

I wouldn’t let a senior seminar student get away with what was in that presentation. I suggested to the psychologist that we trade insights over the year. I am still hopeful that we will.

UPDATE: Just to be clear I didn’t mean this as a dig at psychology but a cosign on Wolfers’ contention that we have much to learn but much to offer as well.
