Directly quoting his biography, Eric J. Vanman is an Associate Professor in the School of Psychology at the University of Queensland Australia.  In this short (15 minute) video below, he uses clear language and succinctly describes the problem and causes of scientific fraud, why it’s pervasive, and what can be done about it.  It’s a great intro for those not scientifically inclined, or for those who might be anti-science willing to hear someone admit scientists aren’t perfect.
