I would love to ask @mattwridley why embryo selection or reducing mutational load couldn't work to meaningfully increase intelligence?
Pretty strange article about intelligence selection. I appreciate the non-ideological criticism, but author should do some more reading on this topic before the next article. Fact: genomic prediction of highly polygenic traits is common in animal breeding. https://www.spectator.co.uk/2017/12/even-if-we-could-create-genius-designer-babies-theres-no-demand-for-them/ …pic.twitter.com/MBlVOuMBr6

I think he just needs to read up on animal breeding literature. This is a great start. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3872177/ … https://www.nature.com/articles/ng.3920 … http://www.tandfonline.com/doi/full/10.1080/1828051X.2016.1172034 …

What about it. Does it prove that there are no unforeseen consequences?

Ridley always has an odd mix of true and false in his genetics stuff. Like his earlier http://www.rationaloptimist.com/blog/gene-editing-and-eugenics/ … - yes, very acute in noting that people *really* value relatedness and this is why sperm donation never took off in the fertile, yet wrong about most else.
-
His criticism of intel importance is also the usual, but weird "but other stuff matters too". Yeah, who says otherwise??? IQ still the most general and important predictor of social success (another is mental illness, but this is less common and hence less important).

I agree most people don't value IQ that much, or even would prefer low IQ, as being more like themselves. But we've bred for IQ in dogs already, ahven't we? And in rats, surely?
-
I think you can we quite sure that essentially no one will breed for low IQ deliberately, tho many parents will not select heavily for IQ per se. They will select for IQ related traits, earning ability, educational ability, good health, height (in men) etc/

His comments make sense from the candidate gene view of consumer genetic health testing, maybe he's just not caught up on the lit/didn't realise they'd use PGS
