Dr. Jennifer Fraser and Richard Zwicky introduce the concept of bullying and abuse not as merely a moral or behavioral issue, but as a brain-altering experience and a verifiable physical injury.

Dr. Fraser details how extensive neuroscientific research shows that repeated exposure to abuse can cause physical damage, including the demyelination of the corpus callosum, the shrinking of the hippocampus due to high cortisol levels, and an enlarged amygdala, the brain’s threat-detection center.

The discussion highlights that this "brain injury" is often unseen, leading organizations to minimize its effect. Furthermore, the conversation explores the damage done to the bully's brain, noting the erosion of affective empathy, and emphasizes the bottom-line impact of abuse culture on businesses, leading to significant stress-related turnover and talent loss.
