And it wasn’t long before actual evidence of this connection presented itself. While phrenology was debunked relatively quickly, it marked one of the first attempts to tether an individual’s traits and characteristics to the physical brain. Phrenology hypothesizes a direct relationship between the physical properties of different areas of the brain (such as size, shape, and density) and opinions, attitudes, and behaviors. Phrenology, a pseudoscience that is not based on any verifiable evidence, was promoted by a neuroanatomist named Franz Gall in the late 18th century. Plato’s renowned student Aristotle mused on a possible connection between the physical body and personality, but this connection was not a widespread belief until the rise of phrenology and the shocking case of Phineas Gage. Later, the philosopher Plato suggested a classification of four personality types or factors: artistic (iconic), sensible (pistic), intuitive (noetic), and reasoning (dianoetic). This theory resulted in four possible temperaments (hot/moist, hot/dry, cold/moist, cold/dry) called humors, which were thought to be key factors in both physical health issues and personality peculiarities.

The ancient Greek physician Hippocrates hypothesized that two binaries define temperament: hot versus cold and moist versus dry. It seems that for as long as there have been humans with personalities, there have been personality theories and classification systems. The history of personality research can be roughly divided into seven periods, each with different prevailing theories and underlying philosophies. To understand how we got to the Big Five, we have to go back to the beginning of personality research. Not only does this theory of personality apply to people in many countries and cultures around the world (Schmitt et al., 2007), it provides a reliable assessment scale for measuring personality. The most prevalent personality framework is the Big Five, also known as the five-factor model of personality. With personality having such a large impact on our lives, it’s important to have a reliable way to conceptualize and measure it. In fact, personality shows a positive correlation with life satisfaction (Boyce, Wood, & Powdthavee, 2013). However you define personality, it’s an important part of who you are. Meanwhile, the American Psychological Association (APA) defines personality as “individual differences in characteristic patterns of thinking, feeling, and behaving” (2017). The definition of personality can be complex, and the way it is defined can influence how it is understood and measured.Īccording to the researchers at the Personality Project, personality is “the coherent pattern of affect, cognition, and desires (goals) as they lead to behavior” (Revelle, 2013).

In the world of psychology research, personality is a little more complicated. It encompasses all the traits, characteristics, and quirks that set you apart from everyone else. Personality is an easy concept for most of us to grasp.

In this article, we’ll define what personality is, explore the different ways personalities can be classified (and how those classifications have evolved), and explain the OCEAN model, one of the most ubiquitous personality inventories in modern psychology.īefore you continue, we thought you might like to download our three Strengths Exercises for free. Which raises the question: how do we categorize and classify something as widely varied as personality? You can meet hundreds, thousands, or even tens of thousands of people, but no two will be exactly the same. While we may have a lot in common with our fellow humans, like race, religion, sexual orientation, skills, and eye color, there is one thing that makes us each unique: personality. A more comprehensive answer might include a description of your beliefs and values.Įvery one of us has a different answer to this question, and each answer tells a story about who we are. An answer could include your name, your job title, your role in your family, your hobbies or passions, and your place of residence or birth.

There are many ways to interpret that question.

It’s a simple enough question, but it’s one of the hardest ones to answer. The Big Five personality traits are all about the following question:
