The second set of groupthink symptoms fall under "Closed-mindedness". This involves "rationalizing warnings that might challenge the group's assumptions".
This entire blog is about how I and others rationalized warnings. For a time I rationalized every problem I encountered with LDS doctrine and tried to keep confrontation at bay for as long as possible. The Church just had to be true. Had to.
The message was, and still is: don't worry about it now! All questions will be answered after death. All problems solved. All doubts resolved. Believe on.
