A religious sect can be described as a cult for doctrinal beliefs, sociological factors, or both.  This episode covers both but focuses on sociological factors where the discussion also encompasses non-religious organization/groups that exhibit cult-like behavior.  An overview of conspiracy theories will be covered.   Aspects of deception will be explored and the difference between deception and questions of truth will be clarified.   The episode will discuss how bad science is used deceptively in medical quackery and unethical product marketing.  This episode is a sequel to the prior one on truth.
