In the book, When Prophecy Fails, Festinger et al. (1956) describe how Mrs. Keech's group reacted when their prediction that the world would end was not borne out. Instead of deciding that the prophecy was wrong, members of Mrs. Keech's group chose to believe that they had saved the world. Festinger suggests that this is because they had given up so much to believe the prophecy that it would have been difficult for them to now decide they had been wrong. This is a good example of:

The principle of attitude inoculation.
The principle of least resistance.
The principle of induced justification.
The principle of clarion.
