As it should when new evidence comes to light to justify it. Ideally, the tools we use would keep up along with those changes while transparently preserving the history and causes of them.
Perhaps that's the tragedy though. At least in the U.S. plenty of people seem unwilling to change their "truth" when new evidence comes to light. When there are actors that seek to make everything political it also makes everything then "tribal".
I think people are more willing to adjust their views as new evidence suggests as long as they never dug their heels in in the first place.
