Nobody knows, but it is sometimes possible to know is whether people's
stories are contradictory.

When it comes to extracting information from people, it is interesting
to do it in an indirect way and hopefully checking the answers against
each other.  Instead of asking them how often they do X, it might be
better to ask Y.  Assuming Y implies X, we know X was done.  Also, if
possible, ask Z too, assuming Z also implies X.  (If they answer no to Y
and yes to Z, we might as decide to discard the information.)

Nobody is saying this is easy to do. ;-)
