Linguists, neuroscientists, psychologists and others have spent decades trying to uncover the ways in which language influences our thoughts, often focusing on abstract concepts such as space and time which are open to interpretation. But getting scientific results isn't easy. If we just compare the thinking and behaviour of people who speak different languages, it's hard to be sure that any differences aren't down to culture, personality or something else entirely. The central role that language plays in expressing ourselves also makes it hard to unpick it from these other influences.
