Sequential choices using signal detection theory can reverse classical predictions

Abstract

Intuition and past theory suggest that if dangers become more common then prey should be less bold. But this prediction should be reversed in many biological scenarios. We provide a simple demonstration that the old predictions of signal detection theory should be reversed, even when the same decision-making threshold is used by the animal regardless of its current state of reserves. In other words, more predators result in prey being *more* bold!
