"A study of identical twins by researchers in Britain and the United States suggests family environment has little influence because nearly half of a person's propensity to be self-employed, or entrepreneurial, is due to genes.
"This relatively high heritability suggests the importance of considering genetic factors to explain why some people are entrepreneurial, while others are not," said Professor Tim Spector of St Thomas' Hospital in London."
Does anyone know if anything similar has been done looking at investment choices? Seems like it would be "relatively" easy to do. But I am not aware of it and a few feeble web searches yielded little.
