“By calculating how much information every syllable in a language conveys, it’s possible to compare the ‘efficiency’ of different languages. And a study published today in Science Advances found that more efficient languages tend to be spoken more slowly. In other words, no matter how quickly speakers chatter, the rate of information they’re transmitting is roughly the same across languages.” The Atlantic: A Rare Universal Pattern in Human Languages.

+ If you speak a slow-ish language quickly, that still works.
