Most people find correcting grammar mistakes and agonizing over possible spelling mistakes to be extremely unpleasant and often rude. And even scientists have shown that people who correct others' grammar mistakes are less pleasant.
Recently, the well-known fact that people who interfere with the expression of others are slightly uncomfortable has also been confirmed by researchers. In a study published in the journal PLoS One, the participants had to read an email with grammar and typos. After that, they answered the questionnaire with which they rate the writer of this message, they later solved it personality questionnaire and gave theirs demographic information.
The personality questionnaire measured five personality traits: extroversion, agreeableness, openness, neuroticism and conscientiousness. The researchers found that more extroverted people they overlook more mistakes as an introvert; more conscientious individuals were more sensitive to typing errors; less acceptable people - i.e. those for whom social norms and being popular are not that important - were very sensitive to grammatical errors.
