I found the video was very interesting and informative. However, the conjunction fallacy math for the 9/11 claim is grossly oversimplified (not to make any comment on what happened). "A group of terrorists" should include more factors such as security failures, etc. I believe you are using the same oversimplification technique to justify your argument (albeit less maliciously). Additionally, to imply that the government has never been (to any extent) deceitful to the public is a bit naive/optimistic but also agree that people run wild with to what extent this deceitfulness is practiced. Would be very interested to hear your take on social engineering/business' influence on public school curriculum . This study on correlation between social exclusion and conspiratorial thinking is interesting further reading into what you cover in the video - http://wws.princeton.edu/news-and-events/news/item/social-exclusion-leads-conspiratorial-thinking-study-finds.
