When 2 scientist talk about something "true", they never mean "no way this could be even slightly false". They mean either "given our present information, this is very very probably true" or "this is very very accurate". Most of the time they mean both. Now, if you want to make a practical decision, in a relatively limited amount of time, you will most likely treat "most probably true, and very very accurate" statement as just true. So OK, there is no "true". But in practical terms, this is only a stretch, an abuse of language. For practical purposes, this is good enough. If you think it's not, go invent a short label that precisely means what you want, and make people use that. Good luck.
