3/ Fear of death is only rivalled by the fear of social disapproval. The latter could be stronger.

I'd say depends of how person sees him/herself, to one who has build entire image by social approval, rejection equals death

4/ Propaganda is just as effective in the modern day as it was 100 years ago. Access to limitless information has not made the average person any wiser.

generic masses have never cared about truth, only the messenger

5/ Anything and everything can and will be politicised by the media, government, and those who trust them.

duh, any movement that affects society is political in its nature; its pretty much nothing else but political thing

9/ Humans can be trained and conditioned quickly and relatively easily to significantly alter their behaviours - for better or worse.

as have pretty much been done for several millenias with beliefs, then with school, now with social media(see point 3)

11/ People who are dismissed as 'conspiracy theorists' are often well researched and simply ahead of the mainstream narrative.

Puppet masters have never liked ones who poke their control and threaten to reveal strings to public

15/ 'The Science' has evolved into a secular pseudo-religion for millions of people in the West. This religion has little to do with science itself.

well duh; humans have always had faith into something, changing it into belief of science becomes just next religion, atheist's are not ones who reject belief, they embrace new god

18/ If you make people comfortable enough, they will not revolt. You can keep millions docile as you strip their rights, by giving them money, food, and entertainment.

dictators starting with roman emperors understood this; happily history also proves that eventually critical point is reached and no matter how much comfort is given it wont be enough
