I’ve often had to explain the difference between temperament and personality — at least from my point of view and experience. Your temperament is that basic set of behaviors and attitudes you were born with. These cannot be fundamentally changed – though behaviors can be changed. This is the premise behind th Myers-Briggs and DiSC tests. Indications can include whether you are extroverted or introverted, prone to anger or criticism or anxiey.
Personality is your temperament modified by life experience. Your personality if the sum total of your experiences on top of your temperament. There are many temperament tests available on line – check out this one which will give you the basics.
And, as always, if you have questions about your temperament or someone elses’, just add the question in the comments or email me at halwarfield(at)outlook(dot)com.
