Is lack of doubt a form of self-cherishing?

Many people frequently make bold and confident claims about what Buddhism is or isn't with little or no humility or doubt. Their views are asserted to be correct, and anything contrary to their view is asserted to be simply wrong or a misunderstanding. My own doubts are sometimes the cause of suffering, but they also protect me from having fixed views which can be erroneous and leave no space for growth, adjustment and wisdom. My view is that the more confidently a view is expounded, the more likely it is to be wrong, and the more likely that self-clinging and self-cherishing are lurking in the mind, but even this view seems uncertain. Perhaps developing contentment with the uncertainty of reality is a part of wise practice, but I can't be too sure of that either.
