EP21 Speech 16 - Why Psychology Struggles - Steven Hayes, PhD

In this talk, Dr. Steven Hayes will claim that most key psychological concepts that have entered into our cultural mainstream contain within them a core conceptual and methodological flaw that makes application of these concepts inappropriate and invalid. Dr. Hayes will explain the error and show how it limits the good that psychology can do for the world. He will then examine a small number of areas of research where significant progress has been made by correcting the problem.
