"As an applied linguist, I study how learning multiple languages can have cognitive and emotional benefits. One of these benefits that’s not obvious is that language learning improves tolerance.
This happens in two important ways.
The first is that it opens people’s eyes to a way of doing things in a way that’s different from their own, which is called “cultural competence.”
The second is related to the comfort level of a person when dealing with unfamiliar situations, or “tolerance of ambiguity.”
