The Adamant Amgdala

Some neurologists have believed for some time that they can identify conservative and liberal thinkers, on the basis of brain activity. The two groups show differences, especially in the activity of the amygdala. Confirmation bias (a tendency to give greater 'weight' to 'evidence' supporting your own world view) seems to operate in this neural region. It seems that, once an individual has a fixed opinion, his/her brain stops them 'changing their mind'. There's now a suggestion that the brains of 'Brexiteers' (people who wanted the United Kingdom to leave the European Union [EU]) and 'Remainers' (who wanted to stay in the EU) are differently 'wired' (https://www.theguardian.com/politics/2023/aug/13/brexit-brain-science-psychology-divided-uk-debate). The basic conclusion is that no amount of 'evidence to the contrary' is likely to get substantial numbers of folk to change their minds about the benefits/disadvantages of being in the EU. Who needs opinion polls, when you've got neurologists!
