Making Cognitive Enhancement Palatable

parrhesia.substack.com

SS: I think that cognitive genetic enhancement is important for ensuring we have a better and lasting future. Many people have an intuitive dislike for the idea of using genetic enhancement to make a baby smarter but have little issue with in vitro fertilization (IVF). I try to build from a foundation of the acceptable practice of IVF to PGT-P for IQ.

I have extensively studied almost all nootropics and therefore know most of the pharmacological markers that influence intelligence, however I have almost zero knowledge about the genetics correlate of hypermnesy, intelligence and rationality.

Does anyone know what are key "genius" genes?

IMHO I don't think intelligence is mostly bottlenecked by standard genetics, I am far more inclined to believe in early nurturial critical periods.

But I do believe in the potential of a practice that has long been forgotten, artificial cranial elongation:

According to scientists their brain volume is not bigger than a normal human being, and as such cranial elongation only solves one bottleneck: space.

If we identify the mechanics that drive the closing of the brain surface in teenage years and find a way to delay it, or if we intensify neuron and axonal growth during childhood via e.g. BDNF, NGF, etc and maybe growth hormone then we might achieve humans with the biggest brains ever.

Don't get me wrong brain size is only one metric and there might be a bimodal curve to it however our current brain size as shown by studies is totally constrained by a mere contingent scarce sugar consumption optimisation.
