When Donald Trump ran for president in 2015, he promised to build wall, drain swamp, bring back factories from China etc he achieved none of these what he did do was not in his campaign promise: a large tax cut, with the deficit induced liquidity expansion fueling a stock market boom, which benefited mostly the large asset owners, not men in street or farms. Yet, his followers believe he was the great fulfiller. They also believe he is a great democrat (he fought election fraud), a devout christian (sent by God to save america), a believer in morality (he nominated anti abortion judges), and so on. These are not based on facts or reasons, but on feelings - trump fans feel that way about him, find ways to justify these feelings, and have no problem coping with inconsistencies and flip flops - reasoning have trouble with these, but feelings over ride them easily. We could say that the current times have reversed the age of enlightenment, when reasoning based on scientific knowledge moved people away from superstition and heuristics based on childhood role learning. Scientists, experts, academics ... have for some years been losing ground. How much is bitcoin worth? It is a matter of feeling among investors, which is why dogecoin, originally started as a joke and even now without a full set of trading and payment capabilities to function as medium of exchange, rose 50 times in value after Elon Musk talked well of it - he chanced people's feelings. In fact the trend started at least 50 years ago, when John Lennon, asked about world peace by reporters, declared that he would promote world peace by staying in bed all day - obviously, people lying down cannot be engaged in war. Lennon expressed certain feelings: desire for peace and distaste for war, need for simple solutions, wanting to listen to nice sounding words they are not based on reasoning. Modern education places much on feeling, e.g., grammar gives kids bad feelings, if they can express their meaning, grammatical mistakes should be ignored. This attitude being prevalent, students learn many subjects in which you do not know that you dont know. People dont know science and technology? just import some indian workers, or export factories to china and let them handle engineering. When EU wanted to expand NATO to Ukraine, did they not worry how Russia would react? Over there as in America, feeling won over reasoning, and will continue to play havoc. Biden era has come, but it remains a trumpian world.
