From Bob Denmark, Garstang, Lancashire, UK
Thank you to Clare Wilson for a very clear account of the latest research in the nature versus nurture debate 24 September, p 36. By the time my three kids hit their late teens, I concluded that their physical and psychological make-up was roughly one-third inherited, one-third due to the influence of family, friends and school, and one-third from outer space. Now, my nine grandkids are in their late teens or early 20s, I haven’t really changed that view, although I’m happy to swap outer space for the effect of randomness.
