Estimating replication rates in psychology

The Open Science Collaboration's interim report, which will come out shortly in Perspectives in Psychological Science, is available. We nearly pulled off the physics trick of having a paper where the author list is longer than the paper itself. I think there are nearly 70 of us (if you scroll down, you'll find me in the H's).

The abstract says it all:

Reproducibility is a defining feature of science. However, because of strong incentives for innovation and weak incentives for confirmation, direct replication is rarely practiced or published. The Reproducibility Project is an open, large-scale, collaborative effort to systematically examine the rate and predictors of reproducibility in psychological science. So far, 72 volunteer researchers from 41 institutions have organized to openly and transparently replicate studies published in three prominent psychological journals from 2008. Multiple methods will be used to evaluate the findings, calculate an empirical rate of replication, and investigate factors that predict reproducibility. Whatever the result, a better understanding of reproducibility will ultimately improve confidence in scientific methodology and findings.
