According to a new study on human behavior, 90% of the population can be classified into four basic personality types: Optimistic, Pessimistic, Trusting and Envious. However, the latter of the four types, Envious, is the most common, with 30% compared to 20% for each of the other groups.

If you're the type of person who doesn't mind what you achieve, just as long as it's better than everyone else, then you're considered envious. Optimists, which account for 20% of the people tested in the study, are those who believe that they and their partner will make the best choice for both of them. Pessimists were defined in the study as those who selected the option which they see as the lesser of two evils - they accounted for 20% as well. The trusting group - who are born collaborators - will always cooperate and who don't really mind if they win or lose.

In order to group the individuals into these separate groups, a computer algorithm was designed to analyze what each individual would choose when placed in a certain scenario - for example, if they were out hunting. The person belonging to the Envious group will choose to hunt rabbits instead of deer because he or she will be at least equal to the other hunter, or maybe even better; the Optimist will choose to hunt deer because that is the best option for both hunters; the Pessimist will go for rabbits because that way he or she is sure to catch something; and the hunter who belongs to the Trusting group will cooperate and choose to hunt deer, without a second thought.

Specifically, this work is part of game theory, a branch of mathematics with applications in sociology and economics, which examines the behavior of people when they face a dilemma and have to make decisions. These decisions will have different consequences which will also depend on what the other party involved decides to do.
