The brain always wants more, even if it doesn't make us happy.

Psychologists from Princeton University in New Jersey decided to find out how people get trapped in an endless thirst for the fulfillment of more and more material desires, and how psychological problems can develop because of this. The simulation experiment showed that the degree of happiness depends on "relative comparison" - people worry about the difference between the material goods they have and those they want to receive. Also, the feeling of happiness depends on our previous expectations. They may change over time. For example, if we enjoyed last summer's round-the-world cruise, we will want to experience at least the same emotions on our next vacation. On the one hand, if you never feel satisfied, you will endlessly strive for the best. On the other hand, constantly devalue what you already have. This can lead to depression and overconsumption.
