A group of specialists from Northwestern University, in Illinois, undertook the task of analyzing the data of just over 1.5 million people, with which they concluded that there are four general types of personality: average, a role model, self-centered or reserved.
This research, published in the journal Nature Human Behavior, revealed that after studying the questionnaires carried out by the participants, from different parts of the world, the results yielded 16 personality types, which the scientists reduced to four, which are based on five traits of character: neuroticism (tendency to experience negative emotions such as anger, worry or sadness), extraversion (tendency to be sociable), receptivity (openness to new ideas and experiences), kindness (tendency to get along with others) and meticulousness (tendency to follow the rules and be careful and industrious).
The personalities were defined as follows:
This term was used for individuals with a more neurotic and extroverted personality type, at the same time that they are not usually open to experiencing new adventures.
These people are not considered neurotic, they are emotionally stable, however, they are neither receptive nor particularly extroverted.
- Role Model
The members of this group are people with low level of neurosis, but high levels in the other four traits. They are totally reliable individuals, good leaders and are always willing to new experiences and open to new ideas.
People in the group — as the name suggests — are self-centered and very extroverted individuals, but tend to show less openness, meticulousness and kindness.
However, specialists pointed out that despite these definitions, people mature and often change their personality. Furthermore, major trends emerge according to age, the researchers report. Younger people tend to go into egocentric personalities while older people would rather belong to the role-model group. Women seem make this transition from the egocentric group to role-model group faster than men, the results suggest. And women over 60 would represent the largest proportion of role-models among respondents.
The results of this study can be useful primarily for people whose job is to evaluate potential job candidates, the researchers point out.
