We should all strive to be happy little robots?

More seriously, on the flip side of the coin (from the genetic and
other factors indicated by Paul) such factors are not generally argued 
to be absolute determiners of any particular effect -- merely "influences". 
(E.g. it is understood from recent breast cancer studies (unless what
I read last week has been superceded this week) that factors linked
with inherited cancer only eventually affect a minority of women 
that HAVE the relevant family history.)

Nor is the universe understood to be so simplistic that only a single 
"influence" determines frequently influences real-world events. 
(And the interactions of such influences are generally non-linear
and hence hard-to-predict in their minutae, AKA they behave "chaotically").

We'll all just have to put up with the thrashings-around of 19th C 
western reductionist science while it comes to grips with some basic 
facts of life ;-).
