A forthcoming psychology paper is bound to provoke some lively debate on matters political. In researching the way people reach moral judgements (and finding in the process that an awful lot of it boils down to subsequent justification of instinctive decisions), the psychologists have concluded that people with conservative political attitudes have more subsystems in their moral processing brain centres than their liberal equivalents. Ample opportunity for spin from both sides with those results, I’d say. Watch closely for the first salvoes!
