But this is a completely different scenario. Here we're dealing with a putative victim. In the other case, we were dealing with a discussion of the scope of societal problems.

In the former case, it's important to support the person; the presumption is that it upset and/or harmed them, and that as a first-person participant, they have a pretty good idea of what happened. Furthermore, in most cases evidence is not easily at hand--so asking for something difficult/impossible before adopting an attitude of support is just adding insult to injury.

However, believing that one has correctly remembered some numbers is not like having experienced harassment or an attack. Unless one has a very vivid imagination, the emotional saliency is lower, and there's plenty of time to check, and the claim is that there is something which by its nature is easily at hand.
