Rationality and Thinking in Foreign Languages
According to a recent study, decisions reached while thinking in a “foreign” i.e. non-native language are more likely to be rational.
From the abstract:
Using a foreign language reduces decision-making biases. Four experiments show that the framing effect disappears when choices are presented in a foreign tongue. Whereas people were risk averse for gains and risk seeking for losses when choices were presented in their native tongue, they were not influenced by this framing manipulation in a foreign language. Two additional experiments show that using a foreign language reduces loss aversion, increasing the acceptance of both hypothetical and real bets with positive expected value. We propose that these effects arise because a foreign language provides greater cognitive and emotional distance than a native tongue does.
For those unaware, the framing effect is a cognitive bias in psychology wherein a person’s choice or response to a question changes depending on how the same question is worded. This is often the case when one framing highlights losses and another highlights gains. This article over at Wired describes the above study as well as an experiment in which exemplifies the framing effect.
