Coming Events

During the Covid-19 pandemic, I will gladly do talks online or media interviews by phone or internet  (see Contact page to set one up), but I will not give any talks in person until we are past this crisis. Best wishes to all during these strange times.

March 26, 2021 (1 PM Central Time): Online talk at 10th annual AHA Freethought Festival, University of Wisconsin - Madison. The conference will be done via Zoom.

Title:  Biology, Religion, and 1/6/21


On January 6, 2021, American democracy was attacked from within as never before. Yet the rioters who desecrated the Capitol and threatened to kill elected representatives saw themselves as loyal patriots defending God and country. How does a mob become this disconnected from reality? What role did religion play? Can we fix this problem? I offer some surprising insights from evolutionary theory, behavioral biology, and the mathematics of electoral systems.
