Spell Czech, for Better or Wurst?

Silly title for a news summary of a University of Pittsburgh study. The study found students who used spell- and grammar-check made more errors than students who just used their head. Of students who were asked to revise a passage without the spell checker, those with higher SAT’s did a much better job (5 errors) than those with lower SATs (12 errors). But when students used Microsoft’s grammar- and spell-check, both groups made more errors, and the students with higher SATs (16 errors) lost their advantage over the rest (17 errors).

I should note that the study sample was a whopping 33 students. I wish the reporter would have included a reference to where the study was/will be published. Via KairosNews.
