> I've only heard "I could care less" from Americans. Back home, I hear (and use) "I *couldn't* care less," which seems to be much more correct. The thing is, dialects often cause it to sound "I could'n' care less," which may have mutated into just "could" over time.

Anyway - shouldn't the subject line be "accurate" instead of "precise"? Accuracy is the measure of how close something is to it's true value, whereas precision is the repeatability of a set of results.

If people misuse language in a consistent fashion, then they would be precise, yet inaccurate.
