Psychological Science in the news again: CNN retracts story on hormone-voting link

It’s not often that wade into retractions in the mainstream media on this blog, but in this case, we’ll make an exception.

As Politico and Poynter — and probably others — have reported, CNN has retracted a story about a yet-to-be-published study in Psychological Science claiming to find a link between estrogen and elections (disclosure: Ivan’s wife works at CNN). Specifically, the researchers reported that the well-documented preference among single women for President Obama might be rooted in their sex hormones, while that of married women for Mitt Romney seems to reflect their own ovulatory cycle. Or something like that.

Here’s the money part of the piece, which can still be found floating around on the web: Continue reading Psychological Science in the news again: CNN retracts story on hormone-voting link

“Invalid data” prompt retraction of another paper from psychologist Sanna

The journal Group Dynamics: Theory, Research, and Practice is retracting a 2003 paper by psychologist Lawrence Sanna, who appears to have been fabricating his data. Sanna’s work, Retraction Watch readers may recall, came under the scrutiny of Uri Simonsohn, who also investigated Dirk Smeesters’ research.
