An interesting study that came out this year suggests that when people think in another than their native language, they are judging risks more rationally:
With several experiments, the researchers showed that those thinking in a foreign language did not fall prey to the typical biases and framing effects, and overall made more rational decisions than those thinking in their own native language.
Why is that? It seems counter-intuitive on first sight, but it makes perfect sense, if thinking in a foreign language helps us slows down. The more awkward way of thinking may lead to less automatic processing and help us think more deliberately.
