I’ve long held that proofreading your own work is a fool’s errand. And no, it’s not because I particularly suck at it, but rather because every writer I’ve ever worked with has cautioned against the practice.
It’s hard to explain to non-writers how difficult it is to catch your own errors; often, in fact, our protestations come across as nothing more than a desire to escape accountability.
It appears, however, that there’s evidence to support our reluctance.
