Yes this is strikingly similar to humans, too. “Not” is kind of an abstract concept. Anyone who has ever trained a dog will understand.

I think its an english language thing (or language in general).

Someone above commented about using the word "Avoid" instead of "do not". "Not" obviously means you should do the opposite but the first word is still a verb telling you to take action.

Not obviously means you should do the opposite

absolutely fascinating! can you elaborate on this?! I can’t put a context to this, like in what context does “not” means to do the opposite?!

I must be dyslexic? I always read, "Silica Gel, Eat, Do Not Throw Away" or something like that.
