A data scientist says he has settled one of the most pressing conundra of the digital age. He has discovered the difference between geeks and nerds. Burr Settles, software chap at crowdsourced translation platform Duolingo, rooted through millions of tweets to find the sorts of words that were used at the same time as either geek or nerd.
Geek – An enthusiast of a particular topic or field. Geeks are collection oriented, gathering facts and mementos related to their subject of interest. They are obsessed with the newest, coolest, trendiest things that their subject has to offer.
Nerd – A studious intellectual, although again of a particular topic or field. Nerds are “achievement” oriented, and focus their efforts on acquiring knowledge and skill over trivia and memorabilia.
You can see his original research – which is pretty darn nerdy [or perhaps geeky, by his definition—Ed.] – here.
