I recently read the linked article which revolves around a thought experiment (Train rushes towards 5 people, you can rescue them by pushing a single person in front of the train. Would you do it?). Apparently, the answer varies, depending on the question being asked in their native language or in another language the people spoke. They worked together with psychologists to understand this relation and the reason according to them seems to be, that the native language resonates stronger in the emotional part of the brain and therefore changes the outcome of an emotional and moral question like this.
If you speak any foreign language, how much do different do you think you appear compared to others? Compared to your 'usual' self, so if you would meet them or have contact with them in your native language? Do you think it has a big difference? My fiancee is not the same nationality as me, so we communicate in English mainly, even though it's not my native language and sometimes I wonder, when her foreign language is good enough, if she might think different about some parts or opinions of me, just because I will be able to express them differently. Do you think that changing languages over the long run in a relation will change things later on? I'm more curious than concerned, but it will be interesting to see. Did you ever use a foreign language to 'hide' something or gain a benefit in a certain situation?
