Adults can learn the personality traits that boost their wages

The World Bank ran the numbers and found that certain personality traits, like being assertive, lead to higher pay. It turns out adults can learn these traits through training, which means these skills are not just fixed in childhood.

For a long time, many thought personality traits were set in stone after childhood. This paper shows that specific traits have a clear economic value and can be taught to adults. This means vocational schools and development programs can now invest in teaching these "soft skills" to adults, not just technical ones. It gives people a new way to earn more money.
