If you'd like to keep up to date with my zany misadventures in psychology, teaching, and skepticism, you can visit and like my professional Facebook page. On it, you will find news from the areas of psychology and skepticism, hilarious things from around teh interwubz, and other good stuff.

Dr. Lack’s clinical interest in evidence-based practice developed while in graduate school for Clinical Psychology at Oklahoma State University and during his predoctoral internship in Clinical Child/Pediatric Psychology at the University of Florida.

He has consulted for and been interviewed by local, national, and international media outlets.
In addition to courses on his clinical and research specialties in the anxiety disorders and evidence-based psychological practice, Dr. Lack also teaches undergraduate and graduate courses on critical thinking, science, and pseudoscience. These recently culminated in the edited, online text Science, Pseudoscience, & Critical Thinking as well as a series of documentaries on pseudoscience and superstition in Oklahoma.

He currently resides in Edmond, Oklahoma with his beautiful wife and brilliant son on a wonderful little property called Freethought Farm.
