A recent study has determined that typing with both hands reduces the quality of responses and grammar. An article on The Ottawa Sun titled Speedy Typing Kills Student Essays states that typing at speed permits someone to input at a faster rate than the mind takes to form coherent thoughts.
Two notable excerpts from the article follows:
Typing can be too fluent or too fast, and can actually impair the writing process.
The result of slowing down was a richer vocabulary in the one-handed writing. This allows a better expression of complex ideas.
I often found that my review process on chapters that were quickly produced were more tedious and painful. Apparently switching to one-handed typing or imposing another handicap may generate higher quality works.
That or it would make my writing more flowery and eloquent. That may work well for Victorian-era literature but not be necessarily suited for today!
