Kool-Aid factor 

A factor present in all institutions measuring the questionable beliefs and practices that people new to the organization must accept in order to fit in and function with others in it. The expression is derived from the Jonestown mass suicide where followers of Jim Jones drank poisoned soft drinks (off brand Kool-Aid).

Alcoholics Anonymous is a great organization, but if you join it, know that it has a Kool-Aid factor.
