ELI5: When held at gunpoint by a shooter, why is it said that telling the shooter personal details about yourself make them less likely to shoot you?

The average person with a gun isn't a hardened killer.  Odds are pretty good they've barely used their weapon before, and odds are even better that they'd rather not be doing what they're doing.

So reminding them that you're a real person that they could be hurting will often make them feel regretful and guilty - which makes it more likely you'll be on your way safely.  The advice I've always heard is just to let them know that they're in control of the situation, give them your wallet/jewelry/whatever if they ask for it, and don't try to escalate the situation unless they try to hurt you or try to kidnap you.
