Throughout the semester, my favorite topic was personality. Learning about the "Big Five" personality traits was really interesting. It really surprised me how accurate a simple personality test was at describing my personality. I was placed in the "scholars" group during discussion, which was low in extraversion and high in conscientiousness. The description of this personality type was quiet, reserved, hard-working, and well-organized. I would use all of those words to describe myself. When I applied the "Big Five" personality characteristics to my friends and family, it was interesting to see the differences between them.
Another reason this topic was my favorite is that I learned that personality is something we can't really change about ourselves; it's a part of who we are. Personality can justify why people are a certain way and can help predict the actions of others based on their personality. For example, my sister is high in extraversion and low in conscientiousness. Based on her personality, I wouldn't expect her to sit quietly at a family gathering; I would predict that she would be highly social and outgoing. Learning about different personality types can be a very useful tool in life and can help in understanding other people.
I thought this was really interesting as well. I think that the circumstances surrounding us when we took the personality tests may have changed the outcome to a degree, but I agree with you in that our basic personality is pretty unchanging.
