Ethical Systems Interview (April 2015)

 Follow me on Twitter

My Approach to Ethical Systems:

My research explores the influences that shape our daily decisions and the implications that these decisions have on our personal lives, professional lives, as well as public policy. Some of my recent research looks at dishonest behavior and attempts to identify what causes ethical people to make unethical decisions and the role that physical, mental, and social environments play in these behaviors. One of the major implications of this work has to do with the troubling role of conflicts of interest and how they infect much of our lives in places we don’t expect them to.
