You open your fridge at 2 AM and feel safe. But your ancestors would have told you to run. That light wasn't protection — it was a beacon.

You'll learn about Brian Most's groundbreaking experiment showing that your heart rate spikes higher in darkness between scary scenes than during them. You'll hear about Joseph LeDoux's Nobel-level research into the amygdala and how your fear circuit rewrote our understanding of survival.
