The results are pretty conclusive. Not only does good spelling and grammar help you avoid embarrassing moments like this:
it also leads to a higher salary in whatever career you choose.
Grammarly, owners of a grammar checking program, and posters of at times hysterically funny grammar bloopers, checked 400+ freelancer profiles from all eight categories of the Elance platform for grammar, spelling, and punctuation errors. To adjust for quality of work, they only selected freelancers with an average rating of four stars or above. They then looked at the correlation between earnings and number of mistakes.
The results are quite clear.
