Organized & consistent - Certain aspects of personality are expressed in different situations, and responses are typically stable.

Although generally stable, personality can be influenced by environment- Example: one's personality may typically be shy and meek, but could flip to that of a leader and active communicator in the face of crisis.
Personality propagates into behaviors- Reactions to people and situations are based on personality. Everything is impacted by personality - from the profession one chooses to their relationships and hobbies.

"The Big Five traits of Extraversion, Neuroticism, Agreeableness, Conscientiousness and Openness have accumulated the most evidence on age changes in personality; relatively less is known about age differences in lower-order traits, and evidence on the development of the higher-order traits is lacking. In this article, I briefly describe the hierarchical structure of child and adolescent personality, summarise research on developmental trends in mean levels of personality traits across the first ten years of life and in adolescence and address gender differences in the development of traits."

"Personality development involves all of the factors that influence how our personalities form and change over time. This can include our genetic background and the environment where we are raised. While personality tends to be pretty stable, it can change over time, especially as people get older.

This article discusses how personality is defined, different theories on how personality forms, and what you can do if you are interested in changing certain aspects of your own personality."

“It is very important,” Kim explains, “that we do not conflate personality disorders with what is simply personality. A personality disorder … is profoundly disruptive to an individual’s daily life. ‘Profoundly disruptive’ is not the same thing as simply being irritating.”

Personality Disorders are grouped into 3 main categories:
- A: Defined by eccentric thinking and/or odd behaviors like paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder.
- B: Defined by behavior and thinking that are excessively emotional and/or unpredictable, like narcissistic personality disorder, antisocial personality disorder, and borderline personality disorder.
- C: Defined by thinking and behavior that is overly anxious and fearful, like avoidant personality disorder, depending personality disorder, and obsessive-compulsive personality disorder.

It is still unclear how exactly personality disorders are formed, but it is speculated that they can be influenced by the following:
- Genetics
- Childhood trauma
- Verbal abuse
- High sensitivity
