Talk:2020 (disambiguation)

20/20 hindsight
I'm trying to understand the expression "20/20 hindsight". This disambiguation page is presently not helpful. The page Hindsight bias (redirected from Hindsight 20/20) didn't help either. If there is an article that explains, please link to it from here. I think I understand the word hindsight; it's the 20/20 part I don't understand. --HelgeStenstrom (talk) 12:57, 15 January 2011 (UTC)
