@mavnn @vrandecic @jay_peper But if you know something has a high probability of not being correct, that is information - so you know the assertion is likely wrong (‘not true’)?
@[email protected] @[email protected] @[email protected] I think we're using formal in different ways and maybe talking past each other? You can formally assess the likelihood of an event in a number of ways, or estimate values using formal methods and that's incredibly useful and may produce informally true results (believed likely with reason) but has very little to do with formal logic: I have a set of axioms and a chain of implications 'we can't prove if this is true or false' is a valid and frequent answer.
