To be clear, normalcy bias isn’t freezing at the first signs of danger like a rabbit who confronts a snake, which is a real behavior humans can succumb to. To suddenly stop moving and hope for the best is called fear bradycardia, and it is an automatic and involuntarily instinct. This is sometimes referred to as tonic immobility. Animals like gazelles will become motionless if they sense a predator is nearby in the hopes of tricking its motion-tracking abilities by blending into the background.
