- A. Is personality stable across situations?
1. The first step in establishing that people really do differ in their “characteristic patterns of thinking, feeling, and behaving” is to show that those differences are indeed characteristic patterns; that they can be observed over and over again across a variety of situations. 2. Of course nobody is going to be exactly the same in every situation, so the challenge is to show there is some stability.
a.
Stability in personality is typically defined as “rank-order consistency , ” which means people’s ranking on a personality trait stays similar from one situation to the next.
b.
Results from many personality studies (e.g., Specht, Egloff, & Schmukle, 2011; Roberts & Mroczek, 2008) show there is indeed rank-order consistency in people’s personalities.
- B. Is personality stable over time?
1.
Another challenge in showing there really are personality differences is to show that personality is persistent—it stays more or less the same over time.
a.
This is important because if personality changes all the time, then it could be that our personality is just the result of the situation we’re in, and when our situation changes, our “personality” also changes.
b.
To show that the differences between people are not just the result of the different situations people are in, it’s important to show that even when major aspects of their situation change—when people go through major life changes—personality still remains relatively stable.
c.
No one would expect perfect stability from birth to death, but the challenge is to show there is some rank-order consistency over decades.
- B. Is personality stable over time?
2.
The research on this topic is pretty clear: People do change, but they don’t change drastically (Specht, Egloff, & Schmukle, 2011; Roberts & Mroczek, 2008).
a.
Very extroverted people rarely become introverted and vice versa.
b.
The rank-order of a person relative to his or her peers stays pretty stable over the course of life.
c.
Interestingly, however, there are some changes that almost everyone experiences—for example, people tend to become more responsible and more emotionally stable as they age.
d.
Because this happens to (almost) everybody, it doesn’t change the people’s rank order.
