What is consistency paradox

Consistency paradox is the observation that a human being's personality tends to remain the same over time, while their behavior can change in different situations.

Many personality characteristics are relatively constant throughout a person's life, but people can act in all sorts of ways (even ones that seem to be opposite of their personality) in different situations. For instance, even the most even-tempered and easy-going person can be driven to violence when put under enough stress or pressure.
