How we change what others think, feel, believe and do
First, collect information assiduously. Garner knowledge from whatever source that can be found or created.
Propagandist information gets sourced from many places, including:
Propagandists use false information but hate being the targets of it. Check that the information you have is truth, rumor or lies. Even lies can be useful particularly when they are spoken by others but it will help you to know what is true and not.
Effective propaganda information management is most importantly about 'spinning' the information such that it has maximum effect.
Particular spinning methods include:
Careful timing can magnify the power of propagandist messages, for example releasing critical information as a politician is coming up for re-election.
'Radio Free Europe' provided cold war communist bloc companies with information about their own countries' activities. It appeared to be independent but was run by Western governments.
'Independent' websites that 'tell the truth' about certain cults have been developed by those same cults.
Information management is at the core of all propaganda. More than anywhere else, propaganda uses the maxim that 'information is power' as the propagandists shamelessly use and abuse it to gain particular ends.
Appearing to use false spin and propaganda can get politicians into trouble and the more successful ones keep themselves personally well away from any questionable activity.
'Black propaganda' is that where the origin is tightly concealed, with only a very few knowing the source. In 'Gray propaganda' the source is not generally known but is not as actively concealed, so the propagandist may at worst claim not to be hiding anything.
Whilst the web is wonderful for many reasons, it is both a propagandist's dream and nightmare. It is easy to set up false information, but it is also very difficult to suppress dissenters.
