9:17 AM | How thinking in a foreign language makes you more rational in some ways but not others
Back in 2012, US researchers showed that when people used their second, non-native language, they were less prone to a mental bias known as loss aversion. This bias means we're averse to the same outcome when it's framed in a way that highlights what's to be lost, as compared with when it's framed in a way that emphasises what's to be gained.

The fate of our earliest memories is something of an enigma. As adults, most of us are unable to recall memories from before we were age three or four. And yet, as toddlers we are perfectly capable of storing and recalling memories from before that age. To solve this mystery, we need to understand more about how infant memory works. Now a clever study has provided a test of just how durable infant memories can be. Osman Kingo and his colleagues in Denmark have demonstrated that three-year-olds […]
