It has long been known that cognitive diversity is important to collective performance. Diverse groups are more productive, more innovative and better at solving complex problems than less diverse groups. And recent research suggests that cognitive diversity also drives scientific progress.
Such research has direct implications for how we regulate reproductive technologies. Late last year, the London Sperm Bank was criticised for its decision to ban sperm donors who suffer from minor neurological disorders, including dyslexia and Asperger’s syndrome. Continue reading
Imagine a world in which genetic interventions (for hair/eye colour, health, strength, happiness, morality…) were tested, safe, effective and accepted.

And unless parents plan to have ten or twenty children, they have no relevant personal experience to draw on for comparing genetic interventions. And the main effects of these interventions are very long term, making the parents even less suited to making the choice in an informed way. Continue reading
