A little on genetic science.

This is something I know little about and though I feel I should care
little for this it's important to understand everything that goes into
the 'science' of the human condition.

When I say science I use it in the loosest possible sense of the term.
Science - real science - finds truths. It doesn't pathologise based on
social and cultural norms. It doesn't use things as crap as the cluster
of symptoms approach. It doesn't vary diagnosis with each person's
prejudice or interpretation of what mental illness is. It doesn't throw
away all the research when it gets to using diagnosis in clinical
practice. It isn't different in the UK, the US and other parts of the
world. It is objective rather than mired in subjectivity.

Anyway, a bit on genetics.
