People Tend To Cluster Into Four Distinct Personality 'Types,' Says Study (arstechnica.com) 214

An anonymous reader quotes a report from Ars Technica: A new study has sifted through some of the largest online data sets of personality quizzes and identified four distinct "types" therein. The new methodology used for this study -- described in detail in a new paper in Nature Human Behavior -- is rigorous and replicable, which could help move personality typing analysis out of the dubious self-help section in your local bookstore and into serious scientific journals. What's new here is the identification of four dominant clusters in the overall distribution of traits. [Paper co-author William Revelle (Northwestern University)] prefers to think of them as "lumps in the batter" and suggests that a good analogy would be how people tend to concentrate in cities in the United States. The Northwestern researchers used publicly available data from online quizzes taken by 1.5 million people around the world. That data was then plotted in accordance with the so-called Big Five basic personality traits: neuroticism, extraversion, openness, agreeableness, and conscientiousness. The Big Five is currently the professional standard for social psychologists who study personality. (Here's a good summary of what each of those traits means to psychologists.) They then applied their algorithms to the resulting dataset. Here are the four distinct personality clusters that the researchers ended up with:

Average: These people score high in neuroticism and extraversion, but score low in openness. It is the most typical category, with women being more likely than men to fit into it.
Reserved: This type of person is stable emotionally without being especially open or neurotic. They tend to score lower on extraversion but tend to be somewhat agreeable and conscientious.
Role Models: These people score high in every trait except neuroticism, and the likelihood that someone fits into this category increases dramatically as they age. "These are people who are dependable and open to new ideas," says Amaral. "These are good people to be in charge of things." Women are more likely than men to be role models.
Self-Centered: These people score very high in extraversion, but score low in openness, agreeableness, and conscientiousness. Most teenage boys would fall into this category, according to Revelle, before (hopefully) maturing out of it. The number of people who fall into this category decreases dramatically with age.

      Women being more average is pretty well-known. Of course, it is a distribution and the extremes are pretty much the same, which is why you get the occasional women who is a world-class scientist and the occasional women who lives on the street, but of both you get less than of equivalent men. You do not get a lot of either though and it is not suitable as a basis for any discussion of superiority. It is not clear to me whether that is done by conditioning by society though, and I think it may well be.

    The 'Average' category was criticized by some of the authors for being 'weak', as it's the largest cluster yet not particularly descriptive. It has yet to be proven that these 4 categories actually correlate with anything important, although follow-up research is checking if Role Models have greater career success.
    Also, these are just clusters, individuals can fall outside of these combinations. One bright spot is that the clusters were named after they were found, rather than before, so they weren't trying to hammer data to fit preconceptions of personality types.
