Throughout recent history rationality has been praised like a sort of superpower. We are taught that rational thinking is the best way to solve problems and make critical decisions. In the bigger scheme of things it also helps on an economic level, due to the fact that if people are being rational decision makers, then it becomes easier for economists to predict trends using their mathematical models.
But are people as rational as most economists would like to believe? Probably not, and as I will explain to you, it is a far bigger problem than just a lack of education.
