“The study found that a person's life satisfaction is very, very strongly connected to their personality traits.
When they removed all the usual problems from how things were measured, they could predict how happy someone was with their life almost perfectly (like 80% to 90% accurate) just by knowing their personality traits.
Even with just a few personality questions, they could predict life satisfaction very well.
They found that being emotionally stable (not getting upset easily), being extraverted (outgoing), and being conscientious (organized and hardworking) were the most connected to life satisfaction.
Being open to new things or agreeable (kind) had a smaller connection.
These strong connections were found in all three groups of people, even though they spoke different languages. They also found that life satisfaction stayed pretty much the same over 10 years, and its connection to personality traits also stayed strong over that time.”
