7 Scientific Theories Why We Like Some People And Don’t Like Others
There are 3 stages of love and different hormones work at every one of them. More than that, it was proven a long time ago that the changes that happen to our brain when we fall in love are comparable with psychological disorders. But what exactly happens to our body and inside of it? And why do we like some people more than others? Science has the answers!
Bright Side offers you to take a look at these 7 interesting studies, experiments, and facts that will tell you more about yourself and will provide you with some key information so that you can make your communication with others much more productive.
Texts with a period at the end are perceived as insincere and/or angry.
Scientists from the State University of New York at Binghamton with Celia Klin as the supervisor held an experiment with 126 students. They had to read dialogues that consisted of only 2 lines: the first one was a question and the second consisted of different variations of answers such as "yes," "yeah," "sure," and so on. The most important thing was whether or not there was a period at the end of the answer. After this, the participants had to evaluate the answer in terms of how true it seemed to them. And surprisingly, in most cases, the answers without the periods were evaluated as being more sincere than those with a period.
We can't use non-verbal signals such as facial expressions, tone and volume of the voice, and body language when we text. That's why we replace all this by text imitation: capital letters and exclamation marks when we are shouting or when we are angry or grammar mistakes made on purpose when we want to show that we are not interested or busy. A period is a signal that we are serious or that a conversation is over, as explained by Mark Liberman, a professor of linguistics. That's why a person who uses a period at the end of a sentence seems angry to us.
We behave better if we are expected to do so.
According to the Pygmalion effect, we behave with certain people in a way that corresponds with what we think of them. This also makes people behave in the way they are expected to.
In one of the articles in Harvard Magazine, social psychologist Amy Cuddy explains: “If you think someone’s a jerk, you’ll behave toward them in a way that elicits jerky behaviors,” says Cuddy. “And then you say, ‘See? He is a jerk!’ This is one of the dangers of stereotypes. When we elicit behaviors consistent with the stereotypes we hold, we tell ourselves, 'See? The stereotypes are right!'"
If you know this rule, you can use it to your advantage and you can be different with a person to make them behave in the way you need them to.
We are drawn to people who have traits that we like about ourselves and the traits we lack.
This rule has always worked even though few people really think about it. It consists of 2 simple parts:
- We like people who have the same traits that we like about ourselves.
- We like people who have positive traits that outweigh the things we dislike about ourselves.
Let's look at this simple example: there is a cute girl who is proud of her appearance but dislikes the fact that she is too insecure. And then she meets a guy is just as attractive but he is also charismatic and confident. So confident that he compensates her insecurity. This mix of specific traits makes his a perfect match for her because they are similar and different at the same time, making each other complete.
We are more inclined to trusting strangers who remind us of someone who once earned our trust.
A group of researchers from the US conducted an experiment where they asked 29 participants to make a choice: either keep $100 or invest all of it (or a part) in something with one of the 3 strangers in photographs. During different games, the participants noticed that one of these men often shared the revenue from the investments, the second one did it occasionally, and the third did it very rarely.
Then, the second part of the experiment started. The players were offered to choose a partner for a new game. 4 people on the photos were absolutely new while the other 54 photographs were changed in Photoshop and the people looked more or less similar to the people from the previous experiment.
As a result, the researchers found out that the participants were more likely to choose someone that they played with before and who made a good impression. And more than 68% of the participants refused the photos of the players who were at least a little similar to the third man from the first game who shared the revenue rarely and wasn't reliable.
Our brain can see how popular someone is.
Almost in all social groups, the popularity of people is defined by their social status and connections. But how do we recognize popular people even when public preferences are different from our own tastes?
In a study published in PNAS journal, experts asked volunteers to estimate how popular people were by their photos from social media. At the same time, the brains of the participants were being scanned. As a result, the scientists found out that certain parts of the brain were very active while trying to estimate how popular someone was. So, a special neural network determines how attractive people are for others. It requires an emotional estimation and the systems of social knowledge.
We like it when someone sees us the way we want to be seen.
People want to be perceived according to the way they think of themselves. We all want our opinions to be shared. This phenomenon was tested many times in different universities: participants with both positive and negative views of themselves were asked who they wanted to communicate with — people with a positive or a negative opinion of themselves.
The participants with a positive opinion of themselves preferred the people with a positive opinion, and vice versa. This is explained by the fact that people like communicating with someone who can provide the feedback corresponding to their own self-identification. This way we can feel that other people understand us, so we are satisfied with the quality of the interaction.
The more symmetrical a person looks, the more attractive they seem.
When you see an attractive person, we don't think that you say "Wow, she is so symmetrical!" However, many studies show that how symmetrical a person is actually plays a big role in their overall attractiveness. Of course, completely symmetrical people don't exist because biology is imperfect. However, it was proven that the lower the level of oxidative stress, the more symmetrical a person is.
In this article from The Independent, you can read about an experiment where several measurements were taken to evaluate how symmetrical some men were. There were such measurements as the size of the ears and the length of the fingers. In the end, a group of women was asked to evaluate the attractiveness of the men by photographs of their bodies and faces. As a result, the men who were more symmetric and less stressed were chosen as the most attractive.
