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…)

Jon Stewart and Stephen Colbert had dueling rallies in DC in October, 2010. Stewart’s was “Rally to Restore Sanity” and Colbert’s was “March to Keep Fear Alive!”

Obviously, Colbert is a great satirist who was poking fun, since we sure don’t need a rally to keep fear alive. Alarming messages are all around us, like the news about global warming or the “Threat Level Orange” announcements every few minutes in the airport.

Some of those messages are true and worth heeding. For example, dumping carbon into the atmosphere must inevitably make the planet hotter; it’s basic physics.

But others are wildly exaggerated: the actual odds of a bad event on your airplane flight are “Threat Level Chartreuse” — a bucket of green paint with a drop of yellow.

How do we tell the difference between real threats and bogus ones? (more…)

Feeling safer is a tricky subject, with complications that can be both personal and political.

(This topic and others are explored in depth in my interview with New Dimensions.)

Yes, there are real threats out there, but evolution and other factors have left a lot of us walking around in a kind of paranoid trance. I’ve been there myself, and the results include feeling less peaceful and hopeful, and more worried and cranky, than is right.

So I hope you find this post helpful.

Is There Really a Tiger in Those Bushes?

Consider these two mistakes:

1.  You think there’s a tiger in the bushes, but actually there isn’t one.

2.  You think no tiger is in the bushes, but actually one is about to pounce.

Most of us make the first error much more often than the second one, because:

·  Evolution has given us a paranoid brain. In order to survive and pass on genes, it’s better to make the first mistake a hundred times rather than make the second mistake even once; the cost of the first mistake is fear for no reason, but the cost of the second mistake is death. (more…)

I saw an interview on TV a while back with the fashion designer, Diane Von Furstenberg. When asked about the people who had inspired her, she named her mother, a concentration camp survivor, who taught her that fear was not an option. Well, that got my attention.

I know, that’s a pretty ominous title, but it was the best I could come up with. Worry not, this is not a treatise on doom and gloom.

What I have been thinking about is that, so often, we decide not to do something because, “I’m too old” or “I’ve never done it before”. The trouble with this attitude is that whether we stretch ourselves or not; whether or not we explore our enthusiasms, the time will pass. If we watch life from the sidelines we are stuck with: “Should ‘uv, would ‘uv, could ‘uv”. Who wants that? (more…)

How did we evolve the most loving brain on the planet?

Humans are the most sociable species on earth – for better and for worse.

On the one hand, we have the greatest capacities for empathy, communication, friendship, romance, complex social structures, and altruism. On the other, we have the greatest capacities for shaming, emotional cruelty, sadism, envy, jealousy, discrimination and other forms of dehumanization, and wholesale slaughter of our fellow humans.

Scientists believe that your brain has a built-in “negativity bias.” In other words, as we evolved over millions of years, dodging sticks and chasing carrots, it was a lot more important to notice, react to, and remember sticks than it was for carrots.

That’s because – in the tough environments in which our ancestors lived – if they missed out on a carrot, they usually had a shot at another one later on. But if they failed to avoid a stick – a predator, a natural hazard, or aggression from others of their species – WHAM, no more chances to pass on their genes.

How much change in the brain makes a difference in the mind?

That’s the issue raised by a very interesting comment regarding my previous blog, “The Brain in a Bucket.”

So I’ve taken the liberty of posting the comment here (hoping that’s OK in blog etiquette; still learning as I go), and then responding. Here it is:

Have you ever seen a real brain?

I remember the first time I saw one, in a neuropsych class: the instructor put on rubber gloves to protect against the formaldehyde preservative, popped the lid off of a lab bucket, and then pulled out a brain.

It didn’t look like much, a nondescript waxy yellowish-white blob rather like a sculpted head of cauliflower. But the whole class went silent. We were looking at the real deal, ground zero for consciousness, headquarters for “me.” The person it came from – or, in a remarkable sense, the person who came from it – was of course dead. Would my brain, too, end up in a lab bucket? That thought gave me a creepy weird feeling completely unlike the feeling of having my heart or hand in a bucket some day – which gets right at the specialness of your brain.
