I sat down with neuroscience PhD Delia McCabe to explore why our brains are struggling in the modern world and what that means for our kids, our politics, and how we handle the AI revolution. Delia has spent her career digging into the effects of nutrition on mental health—either optimizing cognitive function or sending our brains into disastrous feedback loops. We also discuss biological sex differences, the rise of gender confusion, and the cognitive biases that have deranged our public discourse.
