I suggested recently that part of the problem with with LW was a lock of discussion posts which was caused by people not thinking of much to post about.
When I ask myself "what might be a good topic for a post?", my mind goes blank, but surely not everything that's worth saying that's related to rationality has been said.
So, is there something at the back of your mind which might be interesting? A topic which got some discussion in an open thread that could be worth pursuing?
If you've found anything which helps you generate useable ideas, please comment about it-- or possibly write a post on the subject.
The Romantics invented the myth of insane geniuses touched by divinity, but that doesn't mean people holding that belief suffer from amnesia and are unable to list any examples from after the Romantics... Given the lifetime prevalence of any mental illness in the general population, it would be surprising if one couldn't list some anecdotes like Godel.
There's a practically infinite number of genetic changes one could make. Understanding of genetic networks influencing cognition will have to be extraordinarily good before any researchers can write down a completely novel gene or variant which has no natural examples and experiment with it. For better or worse, for the next several decades, we're stuck exploiting natural variants - all interventions are going to look something like 'people with X seem to be smarter, let's try adding X to others or select for it' or 'Y is a rare or de novo variant, maybe it's harmful, let's remove it or select against'.
That's not my mental model at all. I haven't thought deeply about it, but I probably imagine geniuses as an overclocked, supercharged, often highly specialized piece of wetware running on the same-reliability components, possibly crowding out some other capabilities, and frequently having social problems just due to the fact that 99.9%+ of people around you are quite different from yourself.
