The Economist sobre os 200 anos de Charles Darwin

«Another example of economic behaviour that may have deep evolutionary roots is the “herd” mentality that contributes to financial bubbles. In the past, copying the neighbours would have been helpful—in order to avoid danger or to find food. In today’s financial systems, however, it can create instability. The instinct to follow the herd can be rationalised as rational, so to speak, since everybody benefits in the short term by forcing the price up. But it does not look so rational when the instability is exposed by an external shock and the market crashes. In fact, at least part of what seems to be going on is that everyone instinctively feels compelled to copy the others, rather than making an independent assessment of the situation.»

Longo, mas vale muito a pena.
