A study reveals that 90% of the population could be classified into four personality types: the optimists, pessimists, the confident and envious.
Collaborate or Oppose.
The study conducted by researchers at the Carlos III University of Madrid (in collaboration with researchers from the universities of Barcelona and Zaragoza), was conducted on 541 people. To identify these four personality types, the researchers asked participants to resolve hundreds of dilemmas in to two. For each situation, several options were available to them: solutions brought to the collaboration and others who brought the conflict. The dilemmas were based on individual or group interests. The aim was to see whether each individual was in its own way of a dilemma or if it had a behavior similar to that of other people.

These works are based on game theory. This is a set of tools for analyzing situations in which individuals must make decisions. Each person knows his own choice depends on that of others.
The envious are the most Numerous.
After testing the participants in different situations, the authors of the study have developed an algorithm to classify people according to their behavior. Result, 90% of people can be categorized into four groups:
The envious: they represent 30% of the population. It is those who do not care what they do as they are already doing better than others. They always want to have more than others.
Optimists: they represent 20% of the population. They are those who know they will always take the best decision for themselves and their partners.
The pessimists: they represent 20% of the population. These are the ones who choose the solution “least worst” among two bad solutions.
The confident: they represent 20% of the population. It is those who are born to be collaborators. They will always agree with their partners, whether the decision is right or wrong.
A fifth group that does not fit in the boxes.
There is a fifth group (representing 10% of the population) for which the algorithm was not able to define a personality type. According to researchers, the existence of this group to suggest that some individuals do not always react the same way to a problem.
For researchers, these results “go against the theory that human beings act purely rationally”. According to them, this kind of study allows to go further in the existing theories about human behavior by bringing an experimental basis.
This classification allows a better understanding of what happens between two people in a negotiation.
