The editor of the journal Cognition, which published one of the paers in question, is quoted as saying:
If it’s the case the data have in fact been fabricated, which is what I as the editor infer, that is as serious as it gets.
I think Hauser’s going to have to pack it in as an empirical scientist. I just don’t see a way back for him now. Which is a shame.
Additional: Hauser will continue teaching at Harvard’s Extension School. And here’s an analysis of the graph that was apparently made up.
Still more additional: Janet Stamwedle poses thoughtful questions, as she usually does.
