Alfie Kohn, an expert on parenting and education, joins Dr. Justin Coulson to discuss the problems with punishment and rewards in parenting. They emphasize the ineffectiveness of punishment in disciplining children and the negative effects it has on their moral, social, and intellectual development. They explore the importance of fostering intrinsic motivation and finding alternative methods of discipline, such as exploring the child's perspective, explaining the rationale, and empowering them to find a solution.
