I started writing an essay but, mercifully, I think a summary might work better.
Apart from fun/new experiences, is there any point to mindfucking oneself once you've bootstrapped yourself to a certain level of awareness?
Assignment #1: write an essay on the point of a mindfuck.
I see two broad categories of mindfuck - one which works with large memesets/tropes and seems more of a scattershot approach, like leaving
tracts around a city - I see its impact as either accumulative or direct (lightning-bolt inspiration), but either way it increases receptivity if done in a way which doesn't actively make people turn off. The chick-tracts seem to have this memetic fault, although in that case it might just be built into the business model.
The second category of mindfuck involves the internal thought processes/memes, which tend to be significantly more nimble and dynamic. Especially when they camouflage themselves - the evolution aspect gives a strong expectation that your bad habits will find other ways to express themselves, rather like a game of hungry hungry hippos. So meta-programming requires an individual to become aware of their own thought processes/triggers and debug them, sometimes with the luxury of foresight, but often with the associated complexities of doing this in real time.
The social mindfuck does not seem strictly required to push an individual into self-mindfucking/meta-programming, but it probably helps. This sub-culture for instance, seems geared towards that, and does appear more effective at it than mainstream culture - which reflects the respective motivations.
You could try to scribble a third mindfuck category out - that of the group-mind as a tangible form of consciousness. I can't think of any examples of mind-fucks at that level - societies tend to happily march themselves into disaster without a second thought - but perhaps it can be found in individuals escaping the sinking ship of any ideology?
So it seems cleaner to think of it in various recursions as societies and individuals influence each other with increasing levels of sophistication. If so, the point of any mindfuck would be to increase intelligence - we are the universe exploring itself, etc.
This may be kicked in the shins with "No - a mindfuck is just for fun". This construct doesn't disagree with that, but unfortunately can't do so without appearing smug.
By which I mean - if there are literally endless ways to mindfuck yourself, and countless reality tunnels to explore - then a totally random exploration of them will be interesting but will stand a terrible chance of being 'big I' illuminating in any way.
Assignment #2: rewrite assignment #1 to answer this question.
It still seems valid to me.
I.e. Is it possible to use the scientific method to map out the problem space towards the end of recognising the "ultimate mindfuck" (of the current selection) which leads to the most robust reality tunnel currently known? Is there any evidence that the appearance of multiple "truths" is not itself an illusion?
Assignment #3: do assignments #1 and #2 if you still think this paragraph makes sense.
I'm failing these assignments, since I did and I do. The existence of multiple realities does not grant them equality.
