Came across this article the other day called People who constantly point out grammar mistakes are pretty much jerks, scientists find.

They tested 83 participants and had them read email responses to an ad for a housemate. Some had no errors and some had typos and grammatical errors. The 83 subjects judged the person who had written the email based on what they felt about intelligence, friendliness, and other attributes as to what type of housemates they’d be. They were also asked if they spotted any errors and if they did, how bothered they were by it. Those with errors were judged more harshly. However, they found that extroverts were more likely to overlook the errors than introverts.

Ok. We’re jerks. This article had a typo I cannot let get by! They spelled extrovert as “extravert”.
