Not truthfulness; correlation and consistency
If the lie is repeated enough time, and it is consistent in its repetitions it *will* be taken as truth.
AI only aligns with "truth" because in essence "truth" is internally consistent but "lie" needs to be forced to be consistent between multiple parties;
If multiple witnesses seen something and all make a report of it honestly, they might vary but the common points will be consistent with eachother and so that will be scored higher.
A group of liars on the other hand would have to get their stories exactly right for similar thing to happen and so it gets penalized
