Personality tests are one of the benchmarks used in assessing someone, for example when recruiting employees. Admit it, you have also fad to find out your own personality type right?

 During this time, there have been five basic personality traits that are widely accepted, namely neuroticism (emotional control), extraversion, openness, agreeableness (friendliness), and conscientiousness (accuracy).

 But based on a new study conducted by Northwestern University, researchers narrowed the personality to four types.

 The conclusion was based on data of 1.5 million respondents.

 The result of reasearch, published in the journal Nature Human Behavior, this certainly provides a new view in the world of psychology.

 "People have tried to classify personality types since Hippocrates, but the scientific literature previously found it to be nonsense. Now the data shows there are certain types of personalities," said Luis Amaral, Northwestern professor of chemical and biological engineering who led the study.

 The four personality types in question are average, reserved, self-centered, and role models.

 This type of personality in the average group is described as extroverted and has high neuroticism or can withstand high pressure or stress.
Female respondents tend to enter this personality type. Meanwhile, the silent type who is not too extroverted or neurotic tends to be friendly and thorough, and emotionally stable.

 Even so, those in this quiet group are not too open on average. The selfish type is described as a very open person, but not too friendly and thorough.

 Finally, the exemplary type has high value in every trait, such as openness, friendliness and thoroughness, but gets a low value for neuroticism.

 Interestingly, each person's personality type turns out to change over time. As we get older, the number of those who fall into the selfish category decreases, both men and women.

 People are also more likely to be in the exemplary category with age, and women are more likely to be in this group than men.
