I have a skill that normally works as a curse. I can read right over any flaw, getting the gist of the writing, no matter the number of errors. But, that means I am a horrible proof reader. I have noticed there are lots of people (mostly male) who are just like me. I wish I was a better proofer.
I think that is pretty natural. Particularly with men who tend to be more technical in thought than women.
A person who reads quickly would almost certainly be less likely to catch spelling or even grammatical errors.
