What really motivates people

Periodic in the Habr’s tape, you constantly come across attempts to tell “about the motivation” of yourself and other people.

But for some reason, everything always comes down to theoretical reasoning: for the most part, all reasoning comes down either to some personal / alien experience (moreover, de facto absolutely not applicable by anyone else in any other conditions) of people who, as a rule, do not have sufficient control and enough experience, or is it some kind of senseless / useless nonsense from the MBA course (useless for use in any other cultural conditions) from people who have never really led anyone anywhere.

Here's a great video on what really motivates people. This video is based on practical experiments and projects the abstract concept of "motivation" on the application. I note that this is a scientific report and it is simply impossible to put it into practice in a straightforward way.

But the video gives an understanding - how it actually works and whoever can correctly understand it can rethink their personal experience / knowledge and try to very, very carefully apply this knowledge in their practice.

Unfortunately, the video is in English.
