"As a scientist, I think that being able to critically examine things is key to being a happy, healthy human being. I want all people to be able to employ the principles of critical thinking to become scientific skeptics - being open minded, but demanding evidence before accepting something as truth or factual."

To this end, Dr. Lack attempts to spread skepticism and its sibling freethought to as many people as possible. This includes his numerous public talks, his writings, and his position as the Director of the Secular Therapist Project.

The Secular Therapist Project (STP) is a program of the non-profit organization Recovering from Religion. The STP exists to connect those seeking mental health help with secular therapists (be they psychologists, counselors, clinical social workers, or others) who use evidence-based practice in their work. Dr. Lack took over as Director of the STP in January 2016, after being a member of the evaluation team for three years.
