The first layer of internal visual experience I have when reading is a degree of synesthesia (letters have colors). Most of the time I’m not aware that this is happening. It does make recalling writing easier (I sometimes deduce missing letters, words or numbers from the color).
Then there is the “internal blackboard”, which I use for equations or formulas. I use conscious effort to make the equation appear as a visual experience (in its written form). I can then manipulate this image as if the individual symbols or symbol groups were physical objects that can move and react with each other. This apparently allows me to solve more complex equations in my head than most mathematicians. (I believe this is a learnable skill.)
Finally, there are the visual experiences that I use to understand concepts. I’m not sure how to describe these, because these certainly aren’t actual images that are actually possible. More like structures of shapes, spatial relations and other “sub-visual” experiences. It’s not like I can actually visualize an n-dimensional subspace, but it isn’t simply a lower-dimensional analogue either. It looks thin, but with a vast inside, in a way that would be contradictory in “normal” visual experience.
Whenever I read about a concept that seems interesting (e.g. Moloch), I pause. Then I take the verbal experience of what I’ve read, and use it as a guide for some internal thought process to follow. The nature of this process is the creation and manipulation of impossible visual experiences of this kind.
These days my visualization is a lot fainter than it used to be, so faint in fact that sometimes I barely see anything at all, in spite of knowing what I’m (not) seeing. This includes my dreams, and maybe even waking experience (how would I tell?), and I believe this is unnatural. This only seems to have a negative effect on the “internal blackboard”, but not on any of the other mechanisms I mentioned.
Some frames worth considering:
Strong Prune, weak Babble among LessWrongers
Conversation failing to evolve past the low-hanging fruit
People being reluctant to express thoughts that might make their account look stupid in a way that’s visible to the entire internet
Everyone can participate, and as the number of people involved in a conversation increases it becomes more and more difficult to track all positions
Even lurkers like me can attempt to participate, and it’s costly in terms of conversational effort to figure out what background knowledge someone is missing
Most topics that appear on LessWrong are suited for mental masturbation only, they offer no obvious course of action through which people can decide to care about said topics
There is way, way too much content (heck, I’ve only skimmed through the comments under this post)
Long-running conversations don’t tend to happen; therefore there is little incentive in delving deep into one topic, so people (well, me at least) end up engaging with more topics, but in a shallow manner; which in turn creates conditions where long-running conversations are less likely
Due to the way the platform is designed, the only real way to maintain a long-running conversation between persons A and B is if the pattern of response is ABABABAB..., so anyone not being confident at any point is a single point of failure
I also have a suggestion. After the discussion here inevitably fades, you could write another post in which you summarize the main takeaways and steelman a position or two that look valuable at that time. That might generate further discussion. Repeat. This way you could attempt to keep the flame of the conversation alive. But if you end up doing this, make sure to give the process a name, so that people realize that this is a Thing and that they are able to participate in this-Thing-specific ways.
