Those who 'knew the answer all along' may not be quite as clever as they are making themselves out to be.
If you have ever watched a murder mystery on TV and someone in the room announces at the end that they knew all along who the culprit was, even if they didn't, that person may be exhibiting hindsight bias.

While relatively harmless, when this happens it can prevent someone from learning why something has happened or prevent them from accepting advice.
"Too often we actually didn’t know it all along, we only feel as though we did," researchers wrote in the Perspectives on Psychological Science journal. "It’s often hard to convince seasoned decision-makers that they might fall prey to hindsight bias."
