Stuff like this is already known for a long time.

  'known' doesn't mean everyone is aware of something, just that one person knows it. that is a really important reality for interacting in society that I think we often miss in having discussions with others. Just because something is 'objectively true' or 'a fact' doesn't mean that everyone is aware of that fact, when people express surprise at knowledge new to them it seems odd to think that indicating others previously knew that information is somehow a helpful response?
