The concept of the Big 5 Personality Lesson

The five model of personality has these basic core traits: openness to experience, conscientiousness, extraversion-introversion, agreeableness, and neuroticism. They can also be shortened to be CANOE or OCEAN and as stated before are the five core personality traits that a person has. This model is used to help understand and predict relationships between personality traits and success in social, academic, and professional circumstances. The model has been criticized for the limitations it has with respect to the number of personality traits evaluated and for the fact that it is a data-driven model and is not based on a psychological theory. The results of these tests is to figure out how high or low a person is on each trait relative to other people who have taken the test. When a lot of people take these type of tests their scores start to shed light on questions such as if personality differs between groups of people or how a certain trait tends to correspond with an outcome.
