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. For longer and more in-depth commentary, check out my Great Plains Skeptic column on the Skeptic Ink Network.


I also keep a pretty active YouTube account running, which has videos of me giving lectures (like the one below), interviews with various media outlets, and documentaries created by students in my graduate and undergraduate courses.

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 specializes in the treatment of children and adults with anxiety disorders (particularly obsessive-compulsive disorder), psychological assessment, and has extensive experience with persons with chronic tics and Tourette’s Syndrome. 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 writes the "Great Plains Skeptic" column on the Skeptic Ink Network, as well as presenting about skepticism and critical thinking frequently. Dr. Lack is also the founding advisor of the UCO Skeptics, a campus group dedicated to the application and promotion of reason and scientific skepticism in all areas of life.
A native Oklahoman, Dr. Lack grew up in the rural community of Mountain View, where his parents still reside and farm and ranch on land that has been owned by the family for close to 100 years. He currently resides in Edmond, Oklahoma with his beautiful wife and brilliant son on a wonderful little property called Freethought Farm.
