A better title would be: Can we be blinded by what we know to be true?
Unfortunately I don't see a clear discussion starter.
Open mind to what?
Blinded from what?
If you want to discuss cognitive dissonance, then you need to rework the OP.
As written, I'm not inclined to promote this topic. Needs to be clearer.
Missing the mistake is not because of what you know to be true, it was because of what you assumed to be true.
