Each of us has a special personality with specific traits.
Psychologists generally agree that these traits
persist over time, are individually specific, and influence behavior.
Therefore, I declare the Right to Personality,
whereby each individual will have the right to be who they are,
as created by heredity and environment.
Exceptions to this right include
extreme personality disorders and abhorrent criminal behavior
which threaten any individual's Right to Security.
A recent psychology theory defines personality
by the "Big Five" factors:
1) openness (inventive/curious vs. consistent/cautious),
2) conscientiousness (efficient/organized vs. easy-going/careless),
3) extraversion (outgoing/energetic vs. solitary/reserved),
4) agreeableness (friendly/compassionate vs. cold/unkind),
5) neuroticism (sensitive/nervous vs. secure/confident).
Heredity and environment influence each of these almost equally.
But here's a link of 25 other theorists that have other category models
to define the concept of personality.
Carl Jung, for example, believed people relate to the world by
1)sensing, 2) thinking, 3)intuiting, and 4)feeling.
Personality psychologist Lewis Goldberg
is the creator of the International Personality Item Pool (IPIP),
an on-line continual collection of individual personality traits,
an inventory measuring characteristics through testing.
