This is a Question that should be Simple to Answer. Shows that Promote Pseudoscience and Pseudohistory are Often Advertised in ways that are almost Comical and Satirical in Nature.
However, should all Programming be Disregarded if Commercials about such Shows Indicate a Lack of Professionalism and/or Intellectual Discipline, with little regard for Proper Research Methods?
This Depends on the Type Viewing Experience that you want to have.
Suppose you want to be "ENTERTAINED" , WITH NO REAL DESIRE TO EVALUATE THE TRUTH OR REALITY OF WHAT YOU ARE SEEING.
WATCHING "TALL TALES", which are not meant to Impart Factual Data, but to ENCOURAGE "SUSPENSION OF BELIEF" AS A WAY TO ENJOY THE STORY, ARE THE BEST EXAMPLES OF THESE. If this is Appealing to you, Tune In, and Treat it like an OLD FASHIONED "CAMPFIRE" STORY, WHICH IS NOT INTENDED TO BE A LEARNING OPPORTUNITY.
HOWEVER, IF YOU WANT TO MIX ENTERTAINMENT WITH AN EDUCATIONAL OPPORTUNITY, AND VALUE THE "SUBSTANCE" OF WHAT YOU ARE ABOUT TO WATCH, THAN YOUR STANDARDS WILL HAVE TO CHANGE.
THIS IS WHERE THE HANDLING OF THE SUBJECT MATTER IS IMPORTANT. IF ATTEMPTS TO DECEIVE YOU INTO ACCEPTING BOGUS OR FAULTY INFORMATION AS FACTUAL OFFENDS YOUR SENSE OF INTELLECTUAL HONESTY AND INTEGRITY, THEN AVOID CERTAIN PROGRAMS COMPLETELY.
The Problem is: How can we KNOW?
Sometimes, the COMMERCIALS/TEASERS GIVE US A PRETTY GOOD IDEA. If not, the First Few Minutes, INTRODUCING THE SUBJECT, AND THE HOSTS OR "INVESTIGATORS", MAY LEAVE SOME CLUES ABOUT THE MATERIAL THAT IS TO FOLLOW ON THE SCREEN.
CLAIM OR TEASER #1- "THIS WILL REWRITE HISTORY"...OR..."THIS WILL SIT SCIENCE ON ITS HEAD."
Although I am not going to say that it is a CERTAINTY, ANY PROGRAM THAT USES SUCH DIALOGUE TO BEGIN THE EPISODE IS PROBABLY...
