Easier to read is mostly related with predictability of the text. Any time the brain mispredicts the next word, you'd have to go back and re-read.

Unless you are purposely train on that specific way to expression, it ain't easier to read.

I don't know why this is confusing. If I forget to put the "not" qualifier in a sentence, do we agree that it can confuse (or worse, mislead) the reader?
