Fear, Greed, and Crisis Management: A Neuroscientific Perspective
By Andrew W. Lo
A Guest Post
The alleged fraud perpetrated by Bernard Madoff is a timely and powerful microcosm of the current economic crisis, and it underscores the origin of all financial bubbles and busts: fear and greed.
Using techniques such as magnetic resonance imaging, neuroscientists have documented the fact that monetary gain stimulates the same reward circuitry as cocaine – in both cases, dopamine is released into the nucleus accumbens. Similarly, the threat of financial loss activates the same fight-or-flight circuitry as physical attacks, releasing adrenaline and cortisol into the bloodstream, which results in elevated heart rate, blood pressure, and alertness.[...]
Extended periods of prosperity act as an anesthetic in the human brain, lulling investors, business leaders, and policymakers into a state of complacency, a drug-induced stupor that causes us to take risks that we know we should avoid.(…)
If we add to these temptations a period of financial gain that anesthetizes the general population – including C.E.O.’s, chief risk officers, investors, and regulators – it is easy to see how tulip bulbs, internet stocks, gold, real estate, and fraudulent hedge funds could develop into bubbles. Such gains are unsustainable, and once the losses start mounting, our fear circuitry kicks in and panic ensues, a flight-to-safety leading to a market crash. This is where we are today.
Like hurricanes, financial crises are a force of nature that cannot be legislated away, but we can greatly reduce the damage they do with proper preparation. Because the most potent form of fear is fear of the unknown, the most effective way to combat the current crisis is with transparency and education. [...]
