Agreeableness is recognized as one of the five major personality traits in modern psychology, according to the widely accepted Big Five model.
Individuals who score high in agreeableness are cooperative, trustworthy, and warm-hearted towards others.
Such people are more likely to help, share, and resolve conflicts peacefully, making them pleasant to work or live with.
This trait stands in contrast with negative traits like pessimism, which involves expecting bad outcomes; greediness, which shows selfishness; and being judgmental, which implies a critical attitude.
Therefore, Agreeableness best describes a positive personality trait that includes being kind, sympathetic, and considerate.
