Dr Richard Avery has been studying exactly how genes interact with
different types of environment to create such personal qualities as
enthusiasm for business and leadership. Previous research had shown that
people exhibiting traits like sensation-seeking are more likely to go
into business for themselves than less outgoing people. Dr Avery found
the same effect for extroversion (of which sensation-seeking was one
component). There was, however, an interesting twist. His study of 1,285
pairs of identical twins, and 849 pairs of same-sex fraternal twins,
suggests that genes help explain extroversion only in women. In men, the
extroversion characteristic is a result of their environment. In a
second twin study, this time just on men, Dr Avery investigated to what
extent successful business leaders are born, and to what extent they are
made. He discovered that genetic leadership traits certainly exist, but
the way people are raised matters too. The influence of genes on
leadership success is weakest in boys brought up with money---that is,
in men from rich, supportive families---and strongest in those raised in
less fortunate circumstances.
