A very interesting psychological experiment from the times of the USSR.
Ordinary schoolchildren were brought to an improved shooting range in the NVP office, where two targets were installed - for hitting the left one, the student received a ruble of personal money, and for hitting the right one, a ruble was given to the class for general needs.
Before the shot, everyone saw a board “how they shot before him” - which deliberately showed “most shot for their own pocket.” The schoolchildren found themselves in a conflict situation - realizing that his team was not united and almost everyone before him took the ruble for themselves. What the children chose is on the video (turn on auto-translated subtitle).
By the way, a very interesting fact (if you look at the GARF data on repeating this experiment in the republics). Ukrainian Soviet children as one shot into the common pocket, and the Baltic children gave the maximum result of “shots for themselves”, in the Caucasus republics 100% of shots were “for the class” after which they explained “I already have my own money”, and in one southern region after experiment, a rifle was stolen from a shooting range...
By the way, at the same time, experiments were carried out with adults - for example, “canteen on trust” (at a factory) and “self-payment of travel” (on buses). The goal is to understand how Soviet people will behave in future supermarkets and conductorless transport.
In the twenties, the experiments were different. For example, psychologists have found that “wealthy teenagers get stressed by learning about the lives of ordinary people,” and US epigenetics have found that poverty is a disease. No, this is not a joke.
