If you follow politics, a few of the ideas may seem painfully familiar:
"The receptive powers of the masses are very restricted, and their understanding is feeble. On the other hand, they quickly forget. Such being the case, all effective propaganda must be confined to a few bare essentials and those must be expressed as far as possible in stereotyped formulas."
"Propaganda must be limited to a few simple themes and these must be represented again and again. Here, as in innumerable other cases, perseverance is the first and most important condition of success."
"[Propaganda's] purpose must be exactly that of the advertisement poster, to attract the attention of the masses and not by any means to dispense individual instructions to those who already have an educated opinion on things or who wish to form such an opinion on grounds of objective study."
Hitler published Mein Kampf in 1925. The playbook hasn't changed in 87 years!
