Truth may be sacrificed for self-esteem.
“This [Outcome-Based Education plan] is the idea where we drop subject matter and we drop Carnegie Units (grading from A-F) and we just let students find their way, keeping them in school until they manifest the politically correct attitudes. You see, one of the effects of self-esteem (Values Clarification) programs is that you are no longer obliged to tell the truth if you don’t feel like it. You don’t have to tell the truth because if the truth you have to tell is about your own failure, then your self-esteem will go down and that is unthinkable.”
