Economics – Psychology’s Neglected Branch
“It is impossible to describe any human action if one does not refer to the meaning the actor sees in the stimulus as well as in the end his response is aiming at.”
Ludwig von Mises
Economics – to the great dismay of economists – is merely a branch of psychology. It deals with individual behaviour and with mass behaviour. Many of its practitioners sought to disguise its nature as a social science by applying complex mathematics where common sense and direct experimentation would have yielded far better results.
The outcome has been an embarrassing divorce between economic theory and its subjects.
The economic actor is assumed to be constantly engaged in the rational pursuit of self interest. This is not a realistic model – merely a useful approximation. According to this latter day – rational – version of the dismal science, people refrain from repeating their mistakes systematically. They seek to optimize their preferences. Altruism can be such a preference, as well.
Still, many people are non-rational or only nearly rational in certain situations. And the definition of “self-interest” as the pursuit of the fulfillment of preferences is a tautology.
