Using magnetic resonance imaging (MRI) scanners, Professor Rees and his colleague Dr Ryota Kanai at the Institute of Cognitive Neuroscience, UCL (University College London) analysed the brain structures of ninety young adults who had reported their political attitudes on a scale from 'very conservative' to 'very liberal'. They found a strong correlation between an individual's view and the structure of the brain, particularly two regions.
Maybe someone can correct me but this also looks like "we MRIed a small number of students and then compared so many brain structures that we'd be bound to find some sort of correlation with their dubious self reported political leanings."
