I'm not 100% certain this qualifies as a type of Brain Fart but since I cannot cleverly reverse look-up what this is, I'm going to refer to this as a new kind of Brain Fart for the written word. Basically it's when you composing a sentence and there are two or more ways to write a particular segment of the sentence.
Example 1: On other words, for a race two weeks out, it may be tempting to squeeze in a 20 miler to ease your mind, but a shorter long run will do the trick.
writer either meant to write "in other words" or "on the other hand"
Example 2: "But what precisely to they expect to get from the Europeans, let alone the U.S.?"
what they presumably meant: "But what precisely DO they expect to get from the Europeans, let alone the U.S.?" (source: if you want to see if it has been corrected).
