I've given several talks related to publication bias. Here are some that have been recorded and posted on the web.

  1. Francis (2013). The failure of successful replication in psychology. Beyond Questionable Research Practices: Symposium on Good Research Practice in Behavioral Sciences. February 5, 2013. I'm in the fourth video (but the others are worth a watch as well). The talk slides are also available for download. (As of 19 November 2014, the site seems to be down, but a direct link to the video seems to work.)
