When we are confronted with the evidence in any matter, for example a personal or a political issue, the cognitive process in our brain is immediately activated. But surprisingly, the neural circuits in the brain that are normally involved in reasoning or logic do not participate in this process. In fact, when the brain arrives at a certain conclusion which makes us emotionally comfortable, we get the rewards in terms of joy or pleasure and get massively stuck to that conclusion as our own view. This is the finding of a scientific study reported in the Scientific American recently.Perhaps this hypothesis explains the obdurate extreme views some of my senior colleagues hold concerning the dress, gait or stubble of the Prime Minister. These worthy gentlemen leave no opportunity to berate the decision of the Prime Minister to replace high denomination currency.
