Jane Hardyck and Marcia Braden tested a theory about this phenomenon through Mrs. Shepard’s fear of nuclear weapons. One book observed how isolation contributed to Kitty and George reacting differently to this phenomenon than Cleo Armstrong and Bob Eastman. That book uses a group of sibets who carol on December 24 to confirm a prediction that this phenomenon increases proselytization in religious groups. (-5[1])Henry (*) Riecken and Stanley Schachter (“SHACK-ter”) observed this phenomenon after Marian Keech’s failed UFO and flood (10[1])predictions (10[8]-5[1])in (10[1])When (10[1])Prophecy Fails. (10[7])People (10[2])use rationalization, (10[4])the just-world (10[1])hypothesis, and (10[1])confirmation bias (-5[1])to cope with (10[1])this phenomenon, which (-5[1])was investigated by Leon Festinger. (10[3])For 10 points, name this phenomenon in which a person holds conflicting (10[1])beliefs. (10[2])■END■ (10[4])
