Why is man always worried about something?

A team of researchers from Harvard, led by David Levari, proposed to answer this question by bringing volunteers to the lab to do a simple task. It has come to light that this is an inconsistent and relative judgment of people in the external environment.

The participants looked at a series of computer-generated faces and decided which one seemed threatening. The faces were carefully designed to be on a very intimidating and very harmless spectrum, says The Conversation.

As less and less threatening appearances were shown, it has been observed that the definition of this term has changed, including a larger variety of faces. In other words, when the threatening faces were over, volunteers began defining in this way the faces they used to define as harmless.

Instead of being a consistent category, the "threat" depends on how many dangers have been seen recently.

Moreover, this type of inconsistency is not limited to threats. In an even simpler experiment, researchers have asked people to list points by color: blue or purple. It has been noticed that when blue dots became rare, people began to say that dots with a faint purple are blue.

A third experiment in which participants read scientific studies to classify them as moral or immoral has revealed the same inconsistency. And in this case, the judgment was in the context of the environment and context.

Experts say this behavior is due to the fact that our brain likes to make comparisons; we compare what is in front of us with the latest and closest context. There is also a reason - comparisons in a narrow context require less energy than an overall analysis of the situation.

Human brains have evolved to use such narrow comparisons because they provide enough information to handle in the environment.
