Cognitive Dissonance – one of the most established and respected theories in psychology – is under attack. An economist – M. Keith Chen – uses what is called the “Monty Hall problem” to show that the research on cognitive dissonance may be seriously flawed. In this episode I explain Chen’s concerns about the research on and then I propose that a new study which uses neurofeedback to study cognitive dissonance may come to the rescue at just the right moment. Join me to find out how.
Here is the table from M. Keith Chen’s article, “Rationalization and Cognitive Dissonance: Do Choices Affect or Reflect Preferences?” that shows why, once a Monkey has chosen one letter over another (in this case letter A – which could be a red M&M – over letter B, the blue M&M), letter C is likely to be chosen.
