While economists like to pretend otherwise, humans are social animals.
By Blair Fix – The ideal of science is beautifully summarized by the motto of the Royal Society: nullius in verba. It means ‘take nobody’s word for it’. In science, there is no authority. There are no gods, no kings, and no masters. Only evidence.
In this post, I reflect on how ‘taking nobody’s word for it’ cuts against some of our deepest instincts as humans. As social animals, we have evolved to trust members of our group. Among these group members, our instinct is to ‘take their word for it’. I call this the ‘tribal instinct’.
When we do science, we have to fight against this tribal instinct. Not surprisingly, we often fail. Rational skepticism gets overpowered by the instinct to trust members of our group. If the group happens to be powerful — say it dominates academia in a particular discipline — then false ideas get entrenched as ‘facts’.
This is a problem in all areas of science. But it’s a rampant problem in economics. The teaching of economics is dominated by the neoclassical sect, which has managed to entrench itself in academia. Among this sect, I believe, tribal instincts trump the rational appeal to evidence. more>
