Smart people often change their minds. I think that it’s unwise to assume that objective reality holds significant importance in human behaviour. What truly influences people’s actions is the interplay between objective entity, the contextual framework within which it’s perceived, the perception of that context, the emotions or significance evoked by that perception, and ultimately, the emotions that propel behaviour. Unlike the orderly mapping observed in physics, human behaviour entails a convoluted process involving four or five intermediate stages, making it anything but neat.
