[e12e]

Webster doesn't mention any change in use, simply:

"care less : not to care — used positively and negatively with the same meaning <I could care less what happens> <I couldn't care less what happens>"

¯\_(ツ)_/¯

[styfle]

I could or couldn't care less.

The material is very flammable or inflammable.

English is confusing.

[taneq]

The first doesn't mean the same as the second, though. O.o

[e12e]

(On the off-chance you're not being tounge in cheek): No, "used positively and negatively with the same meaning", as in the two differently phrased idioms mean the same thing:

> the different intonations used in saying “I couldn’t care less” versus “I could care less.” [dictionary.com link]

> people who say “I could care less” are omitting the first part: “Like I could care less,” [Slate link]

These quotes seem to sum up those links.

I suppose, these days, for the sake of clarifying that I'm being sarcastic, I should just start saying: "I cloud care less".

[taneq]

To be perfectly honest, I'm kind of 50/50 between a genuine vexation with "could care less" being semantically wrong, and a cheerful agreement that usage defines meaning. The world's inconsistent and so occasionally, in response, am I. :P

[Asooka]

Just use I'd'nt careless.
