Over time, your personality can change — in big ways. But psychologists didn’t always think this to be true. While one’s personality might subtly shift at the periphery, scientists considered it to be largely fixed.

But long-term studies measuring movements in peoples’ “big five” personality traits changed psychologists’ minds. As people grew older, these core characteristics shifted. The big five traits are:

(1) Conscientiousness (how impulsive, organized, and disciplined someone is)

(2) Agreeableness (how trusting and caring they are)

(3) Extraversion (whether a person seeks social interaction)

(4) Openness to experience (someone’s desire for routine)

(5) Neuroticism (a person’s overall emotional stability)

But what triggers these personality changes? Researchers focused on ten life events most likely to alter someone’s personality: (1) A new relationship, (2) Marriage, (3) Birth of a child, (4) Separation, (5) Divorce, (6) Widowhood, (7) Graduation, (8) One’s first job, (9) Unemployment, and (10) Retirement.

Of these 10, researchers found that graduation, one’s first job, a new relationship, marriage, and divorce were linked to the greatest personality changes.

Studies have revealed that our personalities often “improve” with age. In what psychologists have dubbed “the maturity principle,” people tend to grow more extraverted, agreeable, and conscientious as they grow older, and less neurotic. The transformation is gradual, essentially unnoticeable to the individual. But after many years, almost everyone can reflect on their past selves and be amazed at the differences.

Possible Preaching Angle:

1) Christlikeness – We can also add to the “life changing events” Salvation, Persecution as a Christian, and Life-threatening illness. These events can also be used by God to refine us and bring us into conformity with the likeness of his Son. 2) Fallen Nature – Of course, we shouldn’t overlook the fact that these same “life changing events” can cause some people to grow bitter, disappointed, and angry. Life changing events have a way of revealing what is truly in our heart.
