@ArdainianRight In academia, especially in recent decades, very little, maybe none.
But in private sectors, and legislation in past decades, there is some good things that came out of it.
Studies of panicked crowds allowed fine-tuning of width of passages in planes and gathering places.
The right width prevents people from getting jammed in passages, and has saved lives on occasion.
The shape of passages, and the choice of doors, can prevent people from getting trampled.
Making areas like airports and trains stations, more intuitively traversable, and speeding things along is another use.
Works amazingly in Japan.
Everything is marked with color and shape, and the colors are chosen such that color blind people can still navigate.
Markings on the floor help you find your way when its crowded, and you can't see signs over the heads of people around you.
Etc...
In the field of law:
"A fool in a hurry" is a standard accepted by most courts on the planet.
It's the reason why you can't have a bottle of bleach have the same shape and color as a soft-drink, and sell those side by side near the register.
All of that is pretty old stuff though, decades old at the latest.
So much of academia these days is corrupt, and the various industries basically have things figured out, as far as benevolent uses of social science is concerned.

@Terry Maybe it just shat itself, notoriously bad planes that malfunction constantly.
I draw, code, and make memes sometimes.
