This recent series of posts has used the example of Stephen Colbert’s satirical “March to Keep Fear Alive” as a timely illustration of a larger point: humans evolved to be fearful — a major feature of the brain’s negativity bias that helped our ancestors pass on their genes. Consequently, as much research has shown, we’re usually much more affected by negative — by which I mean painful — experiences than by positive ones.

Besides the personal impacts of this bias in the brain, it also makes people, and nations, vulnerable to being manipulated by threats, both real ones and “paper tigers.” Colbert is mocking those who play on fear, since we surely don’t need more efforts to keep fear alive.

Your Brain on Negative
Painful experiences range from subtle discomfort to extreme anguish — and there is a place for them. Sorrow can open the heart, anger can highlight injustices, fear can alert you to real threats, and remorse can help you take the high road next time.

But is there really any shortage of suffering in this world? Look at the faces of others, or your own, in the mirror, and see the marks of weariness, irritation, stress, disappointment, longing and worry. There’s plenty of challenge in life already — including unavoidable illness, loss of loved ones, old age and death — without needing a bias in your brain to give you an extra dose of pain each day.

Yet as my last post explored, your brain evolved exactly such a “negativity bias” in order to help your ancestors pass on their genes — a bias that produces lots of collateral damage today. (more…)

My previous post used the example of Stephen Colbert’s satirical “March to Keep Fear Alive” as a timely illustration of a larger point: humans evolved to be fearful — since that helped keep our ancestors alive — so we are very vulnerable to being frightened and even intimidated by threats, both real ones and “paper tigers.” With this march, Colbert is obviously mocking those who play on fear, since we certainly don’t need any new reminders to keep fear alive.

Some Background
This vulnerability to feeling threatened has effects at many levels, ranging from individuals, couples, and families, to schoolyards, organizations and nations. Whether it’s an individual who worries about the consequences of speaking up at work or in a close relationship, a family cowed by a scary parent, a business fixated on threats instead of opportunities, or a country that’s routinely told it’s under “Threat Level Orange,” it’s the same human brain that reacts in all cases.

Therefore, understanding how your brain became so vigilant and wary, and so easily hijacked by alarm, is the first step toward gaining more control over that ancient circuitry. (more…)
