Psychologist Woo-kyoung Ahn devised a course at Yale called “Thinking” to help students examine the biases that cause so many problems in their daily lives. It quickly became one of the university’s most popular courses. Now, for the first time, Ahn presents key insights from her years of teaching and research in a book for everyone.

Thinking 101: How to Think Better to Live Better There are many thinking errors that we commit, but merely knowing what they are doesn’t always prevent us from repeating those errors. For example, consider confirmation bias, a tendency to seek only the evidence that confirms one’s belief. During the talk, it will be demonstrated that even those who may have heard of confirmation bias can easily fall for it. Various real-life examples will be presented, including what happens when a person learns about their genetic profiles and how this bias leads to inequality in the society even when one does not have any prejudice. Then, it will be discussed why we have evolved to have such biases in thinking. Finally, scientifically tested methods of counteracting the bias will be explained, along with other actionable strategies one can adopt in real-life.
What Can Go Wrong in Clinicians’ and Clients’ Minds When Mental Disorders Are Biologically Explained…And What Can Be Done About It Mental disorders are increasingly understood in terms of biological mechanisms. What are psychological consequences of explaining Major Depression, for instance, in terms of chemical imbalance or genetic predisposition rather than traumatic, stressful events? It has been generally considered that biological explanations for mental illnesses would reduce blame on those who suffer from them. However, we discovered a number of unintended negative consequences of construing mental disorders in terms of biological mechanisms. This talk will review some of these pitfalls and ways to avoid them from the clinicians’ and patients’ perspectives.
