Biologists know that complex traits are typically associated with genetic variation between individuals. Nevertheless, if we hear on the news that obesity, antisocial behaviour or some other disorder has a strong genetic component, we are likely to attach special significance to this ‘fact’. We may be less likely to attribute social factors as a cause and we may be more likely to accept a technological or pharmaceutical solution as a remedy. The disorder may also acquire a credibility and a sense of inevitability that it previously lacked. The reasoning that leads to these conclusions has a certain logic, after all we investigate causes primarily so that we can find remedies, but nevertheless we need to be careful that our thinking is well-founded.
