I noticed that German speaker often use phrases like
Ich vermute nicht, dass das [let's call it A] stimmt.
What do they mean? Do they mean that they conjecture that A is false? Or do they mean that they just do not want to claim that A is true (and maybe do not have an opinion in neither direction)?
How to unambiguously express
- that one conjectures A to be false
- that one just does not want to conjecture that A is true?
