yeah, it has to do with left/right brain stuff as well, there's lots of axes of polarity going on and people tend towards one side of most of them

manipulating large groups of people they actually play both sides off against each other, and part of this has to do with the brainwashing/cult thinking dynamics that is commonly referred to as "identity politics" these days

people do it a bit, but they deliberately push it hard, influencers are generally some kind of cult figure who gives their followers all their soundbites and hot buttons, and in the background behind the curtain they are directing things using various techniques, like the one that stopped me using Facebook about 8 years ago was that they were deliberately making my feed boring, and then they started putting ads in between the posts that were already repetitive and uninteresting that they thinned out from what my follows actually were posting

this is how they do the opposite of driving engagement, trying to push a demographic to the margin by isolating them

and then there is the opposite, of course, so if you do a lot of identity bullshit associated with some influencoor or category, they will often poke you periodically with the 2 minutes of hate to give you the struggle session and reinforce your cult identity

i'm pretty sure the techniques are even more meticulously designed than that, i'm just giving a quick summary of some of the main techniques to do with polarities
