I always thought about that like "cultural something". I remember that here at Brazil it was seriously common to see on TV programms showing and promoting heavy jokes with random people in streets and avenues. Today, I still see some youtube channels and Tv Programs producing that type of content but a little more "controled".

Lol that’s a good question. I think the answer is strictly opinion. I personally don’t like pranks or “social experiments”. I think people who like them either gain some sort of sadistic joy from watching misfortune befall others. A term called Schadenfreude. People also like things that are perceived to be shocking, because it causes them to release adrenaline. As for “social experiments”, the term is not aptly named because there is no scientific process of experimentation involved. Often times their are either faked or called a “social experiment” to mitigate backlash. They are usually used to push a creator’s narrative and create false evidence to support it. Some actual psychological and sociological research does exist on social media platforms, but it’s probably not what you’re referring to.
