I believe that a lot people are quite comfortable in being hilariously wrong, look at any modern political discourse, but the problem in my mind is that people aren't equally prepared to self-reflect and admit fault or reconsider a position.
At the same time though, I do find myself often times at work qualifying things with "I think" or similar phrasing, and I'm still not sure if I do it to avoid embarrassment or if it's to not come off as too arrogant. Maybe it's both.
