1. I don't like not knowing = I like knowing
2. She isn't unattractive = she's attractive
3. I haven't found nothing = I have found something
4. I dislike nobody = I (probably) actively like some people
These are just a few simple examples...double negatives can express many nuances of meaning, but hope this helps!
Hello Finta,
Double negatives, without the necessary intonation, don't often express a positive.
For #1 above, there is a strong assumption that people do like to know things so seemingly, it points to a positive.
But for #2, it doesn't follow that a person described as "not unattractive", is attractive.
The notion that a double negative makes a positive was a prescriptive argument against double negatives that used fallacious reasoning.
"I don't have no money" does not, to any native speaker, mean that "I've got some/a lot of money".
Similarly, for your #3, it can't be concluded, in fact it would be a false assumption to conclude that the speaker had found something.
