Fear Factor: How Herd Mentality Drives Us

"Group Think" Has Its Advantages When Confronting Lions ... But What About Wall Street?

    Find out what each part of the brain does, and when in a person’s life these areas are developed.

(CBS)  Many animals prefer traveling in the safety of a herd. Josh Landis looks for signs of a "herd mentality" among humans:

Birds do it. Bees do it. Even wildebeests do it.

One by one they gather in big groups - and think and act as one.

What is herd mentality?

"It's the idea that the individual members of a herd relate, behave in a similar fashion," said Pat Thomas, general curator at the Bronx Zoo. "And that's so that they don't stand out and appear different than their group mates."

"If they act too much out of the norm, more often than not they're singled out and identified by a predator - and don't survive very long."

Herds can be awesome, moving and flowing in masses, reminding us that in nature there's the quick - and the dead.

And those who stay scared are more likely to stay alive.

Fear: It makes animals run in herds. Could it also cause otherwise thoughtful people to stop thinking for themselves and follow the crowd?

Look at Wall Street …

See-sawing stocks. Rallies and crashes. Investors buying and selling before they've had time to think.

"We are mammals, just like the wildebeest in the plains of the African Savannah," said Andrew Lo, who studies emotions and economics at MIT.

He says when fear sets in, we have little choice but to behave like animals, using a different part of the brain - what some scientists have called the "mammalian brain."

At Emory University in Georgia, Dr. Gregory Berns showed us how the brain reacts to fear.

It comes from a part of the brain that's called the amygdala, the seat of the fear response.

That is what kicks into overdrive when your 401(k) tanks.

"Whether it's the fear of being the odd person out, whether it's the fear of uncertainty or the fear of losing your shirt in the market, the fear starts to compel you to do something, because a million years ago, that fear meant you probably had to run or fight," Berns said.

But reactions that saved our ancestors from saber-toothed tigers don't make as much sense on the floor of the Stock Exchange.

Financial historian Jeff Madrick says that's how we got into trouble in the first place - by developing the notion that the stock is highly rational. "That encouraged this herd behavior," he said. "People would say, 'The stock market is right. Let's get in here.' That was the mythology that fed the herd behavior."

So the group think that helped build the bubble is now leading the charge to pop it.

"I think there's probably a panic now," Madrick said. Berns agreed: "You could call it panic; I would."

But the Bronx Zoo's Pat Thomas says, "It's definitely a survival mechanism."

"The research that neuroscientists have developed seem to suggest that herd mentality, on the downside - that is, in reaction to panic and fear - is far more powerful than the herd mentality associated with greed - herd mentality on the upside," said Lo.

"Because fear trumps greed?" asked Landis.

"Fear always trumps greed, that's right," said Lo. "From an evolutionary perspective, it's a lot more important for you to be scared and run away from danger than for you to be excited and happy and thrilled about your life."

"It's better to be scared and alive than -"

"- Happy and dead, yeah," Lo laughed.

Yes, we may be smarter than beasts of burden, but we're still creatures of habit.

The herd mentality can be seen when "David koresh told me he is a prophet and the other right wingers armed in the compound believe him, I guess i should believe too" or "the republicans told me that bill clinton was wagging the dog when attacking bin laden so I will believe that he was wagging the dog also" or "president bush is telling us that the economy is doing wonderful and that everyone should stop whining so I guess I will keep on investing in stocks because nothing will happen to us just like president bush told us, because he is christian and never lies" or the now classical "the GOP paid scientistslobbyists were telling us that there is no such thing as global warming so I said stop the global whining just like almost everyone else even though the rest of the planet and a few mavericks scientists said there was"....................
these are the same people that believed the earth was flat or that the sun goes around the earth just because the church said so, these are the same folks that attended executions of witches hundreds of years ago, like a herd and they are the same ones that screamed and cheered in those events, today they direct that energy supporting the troops, the cowboys, the spiritual revival etc.....

the best part of it all is that they missed on their predictions and were indeed misled like the herd they are.

the herd mentality happened right after 9-11, the pat tillman types that joined without asking basic intelligent questions such as "are there really weapons of mass destruction"? or "why is the whole world telling us to not invade iraq and yet our government says we should?" or " everyone in my house goes to church on sunday I guess I should too" or " my friends do drugs and drink every friday, I guess I should too" or "pop serve in a war, and so did grandpop, so that means I should serve too even though the country is not at risk".

You''re exactly right. The Rep''s still haven''t learned that we''re not gonna be frightened into voting Rethuglican again.

They''ve cried wolf too many times and used it to line their pockets at our expense.

We''ll hear em cryin wolf right up till Nov 4th, after that we''ll just hear em crying.

You are COMPLETELY OFF BASE!

Obama plans to reduce the taxes of 95% of the working people in this country, and increase the taxes of 5%. McCain wants to reduce the taxes of the top 5%, and scr/ew the rest.

"Fear is the mind-killer.
Fear is the little-death that brings total obliteration."

And that, folks, is why the republican strategy this election is to make you afraid... fear the terrorists, fear the black men, fear everyone with a different religion, fear the socialists, fear the "liberals", fear... fear... fear!

If you buy into that fear, you become the kind of animal that yells out "kill him" at political rallies. You become a moron like "Joe the plumber", believing McCain will reduce your taxes (or make you safer, or whatever) EVEN THOUGH THE FACTS DISAGREE.

Isn''t about time for the people of this country to grow up, to start behaving like actual human beings, to use their God-given intelligence to pick a leader who has a chance to step away from the precipice, rather than continue the mad rush to destruction?

Obama isn''t perfect; no one is. But McCain is completely wrong about the economy, wrong about the war, wrong about EVERYTHING. And he can''t even make up his mind from one day to the next (or even from one hour to the next!) The choice this time isn''t even a close call.

In the upcoming election, sane people will vote for Obama and the suicidal and the delusional and the in.sane will vote for McCain. On election night, the numbers will tell us whether we''ve taken a step towards humanity or have descended into madness.

Good luck!

With Barack Obama as president, all the wealth in America will be redistributed to those who refuse to work for it.

ALL Democrats try to do this.

Democrats ARE the herd.

That''s why we still need the GOP to stop them from doing EVERYTHING they want.

Why, poor old Slick Willy got so frustrated that he had to make himself feel better with a girl named Monica... or so he said.

My stubborn streak reasserted itself and I dug my heels in about 2 years ago.

As far as the herd mentality? Speak for yourself because you certainly aren''t speaking for me. I didn''t give you permission.

LOL! That is so true (below). I wish I had said this. Bravo! Democrat=hypocrit.

Democrats PERSONIFY the "herd" mentality.

The Democrat plan has ALWAYS been

Do more to help the poor

Work to protect the environment and develop "clean" energy sources

Relieve the populations of any form of personal responsibility - even when they want to keep some.

But what they REALLY do is

Chase women

Drink

Kill a few people and call it an "accident."

Make themselves rich

Get re-elected by renewing promises to do the plan

When someone asks them how much of the plan have they actually accomplished, they say "What?"

The Clinton years would have been a GREAT time to start developing some alternative energy sources. But instead, people drove Hummers and monster SUV''''s, because oil was cheap and the supply would NEVER END.

Opportunity lost...

Fat chance ***, not gonna happen. You''ve stampeded enough trailer trash and closet Klan members over the years, but it''s all caught up with you.

In the face of total economic collapse and a major depression on the horizon, you''ve got zip, nada, nothing, zero, to help the situation.
