it becomes a problem when the group’s beliefs are at odds with reality

But this becomes a problem when the group’s beliefs are at odds with reality.Imagine watching your favorite sports team
commit a serious foul.You know that’s against the rules,but your fellow fans think it’s totally acceptable.The tension between
these two incompatible thoughts is called cognitive dissonance,
and most people are driven to resolve this uncomfortable state of limbo.You might start to blame the referee, complain that the other team started it,or even convince yourself there was no foul in the first place.In a case like this,people are often more motivated
to maintain a positive relationship with their group than perceive the world accurately.
