This week on Sinica, we're delighted to be joined by Thomas Talhelm, Ph.D. candidate in psychology at the University of Virginia and author of a recent paper proposing a fascinating connection between rice and wheat-growing communities, and persistent differences in psychological orientations of people from different parts of China. So join us as we talk about divorce, collectivism and violence, and get the dirt on all the various tests psychologists are using to measure it all here in the Middle Kingdom.

And even if psychology isn't your thing, we suspect that breathing is -- which is another reason to listen. In addition to his growing reputation in academic circles, Thomas is also known in China for his production and proselytization of do-it-yourself air filtration kits, which he sells through his company Smart Air Filters. If you are interested in getting a filter without spending a fortune, be sure to check them out. [standalone mp3 download]
