SMOKE GETS IN YOUR EYES


The theme this week at Goat Rope is the bystander effect and how and when people decide to intervene--or not. If this is your first visit, please click on earlier entries. You'll also find links and comments about current events.

Psychological experiments as well as unfortunate events have suggested that there's something about being part of a larger group of people that makes us less likely to personally take action to help other people in a bad situation.

But it doesn't stop there--sometimes being part of a group makes us less likely to take action to help ourselves.

Researchers Darley and Latane (see yesterday's post) tested this in another ingenious experiment in which naive subjects were given a routine task in a room where smoke poured from the vents. When they were the only people in the room, most people (around 75 percent) reported the smoke.

But when they were in the room with two other people who expressed no concern about it (and were instructed as part of the experiment to ignore it), only ten percent reported it--even when the room was full of smoke at the end of the six minute experiment.

When they tried the experiment with three naive subjects in the room, i.e. nobody who was "in on it," people only reported the smoke 38 percent of the time.

It seems in general that we take their cues about the nature of a given situation from other people and if others don't seem to think it's a big deal, we're not likely to either--even if it could be a matter of our own life and death.

Time seems to be a factor in the decision to act as well. It seems that the longer people wait to take action, the less likely they are to do so.

Some days, El Cabrero is reminded of one of Dylan's darker lines: "We're idiots, babe. It's a wonder we can even feed ourselves."

THE RECESSION AND THE WAR are the subjects of this op-ed by economist Dean Baker. Short version: it made things worse, but so did bad domestic policies and priorities.

EVANGELICALS ON THE MOVE. Here's an interesting article from The Nation about changing attitudes among evangelical voters. The religious right's lock on the group has been broken or at least challenged.

NEW BLOG FROM GOOD JOBS FIRST. GJF has long taken the lead in the fight for job quality standards, smart growth and accountability in economic development policies. The new blog, Clawback, is a welcome addition.

QUICK, ROBIN, GET THE SHARK REPELLENT! I did not make this up. According to a brief item in The Week Magazine, designers of the Shark Shield, a devise intended to keep sharks away by emitting electronic waves, may have to go back to the drawing board after a shark ate one of their units.

MORE ON CLIMATE CHANGE IN WV. Here's WV Public Radio on local responses to climate change (or the lack thereof).

RETIRING BABY BOOMERS might not signify the end of the world after all, this Foreign Policy article suggests.

THE BYSTANDER EFFECT


Image courtesy of wikipedia.

In the wake of the highly publicized killing of Kitty Genovese in Queens, in which news reports stated that a number of people witnessed without intervening, (see yesterday's post) two psychologists decided to study how people respond to the sufferings of others.

John Darley and Bibb Latane were obviously unwilling and unable to replicate that tragedy, but the did design an illuminating experiment that showed that people often take their cues about the seriousness of a situation from other people.

As Lauren Slater described the experiment in her entertaining book Opening Skinner's Box,

They recruited naive subjects at New Your University (NYU) to participate in what appeared to be a study of student adaptation to urban college life. A student sat in a separate room and spoke into a microphone for two minutes about the challenges at NYU. In a series of separate but audio-wired rooms were tape recorders carrying other student's stories, but the naive subject didn't know the voices were pre-recorded; the subject believed they were actual neighbors.


When one of the pre-recorded "students" who had previously self-identified as having severe epilepsy pretended to have a major seizure, the scientists observed how long it took for the subjects of the experiment to notify the experimenters that something was wrong. The pretended seizure lasted for a full six minutes.

Here's what they found. Subjects were likely to intervene when they believed that the only other person in the experiment was the person with the seizure. The rate was 85 percent.

But when they believed that four or more other people were listening as well, they were much less likely to intervene. The rate was 31 percent.

In other words, as Slater put it, "There is something about a crowd of bystanders that inhibits helping behavior." So much for the old "safety in numbers" theory. The term for this is "diffusion of responsibility," about which more tomorrow.

Another interesting finding was the time factor. Ninety five percent of those who intervened did so in the first three minutes of the apparent crisis. The longer people waited to intervene in a bad situation, the less likely they were to do so.

Does that sound familiar?

SPEAKING OF PSYCHOLOGY'S DARK SIDE, here's Wired interview with Philip Zimbardo, who conducted the Stanford Prison Experiment and wrote the recent book, The Lucifer Effect: Understanding how Good People turn Evil.

TALKING SENSE. Here's conservative Ben Stein taking on the myth that tax cuts "pay for themselves."

$12 BILLION A MONTH AND A LOT OF DEAD AND INJURED PEOPLE. Must be the Iraq war we're talking about.

THEOCRATS NO MORE. This is an interesting article on the disillusionment with the religious right by some of its former leaders.

YOU DON'T NEED A WEATHERMAN to know climate change is for real. In a welcome shift, Southern Baptists have taken a stronger stand on countering it. Here is the AP and NY Times on the subject.

A THEORY OF NAMES. Here's a good one on the effects of unusual names on children. Short version: they make for better self control. I guess Johnny Cash was on to something.

I DIDN'T NOTICE THIS, but WV small schools advocates won a round with a bill this session that limits school bus rides.

CONFORMITY AND DISSENT, PLUS STUFF ON TRADE, TAXES and POLAR BEARS





Caption: Venus is a non-conformist.

It seems to El Cabrero that most of the horrors and crimes committed by humanity over the ages have not been perpetrated by the occasional sociopath but by fairly "normal" people either doing what they are told or going along to get along.

I call them "sins of obedience."

Partly because we are inherently social animals (or else we wouldn't have lived this long), there are powerful pressures on us to conform to perceived social norms. Much of the time,that's not a bad thing. But it often can and has led to disastrous consequences.

"Group think" has been blamed among other things for the bad intelligence going in to the unnecessary war in Iraq, to use just one example.

A famous psychological experiment Solomon Asch first conducted in the 1950s shows how conformity can lead people to ignore the obvious evidence of their own senses.

As Cass R. Sunstein describes it in his recent book Why Societies Need Dissent,



In these experiments, the subject was placed in a group of seven to nine people who seemed to be other subjects in the experiment but who were actually Asch's confederates. The ridiculously simple task was to "match" a particular line, shown on a large white card, to the one of three "comparison lines" that was identical to it in length. The two nonmatching lines were substantially different, with the differential varying form an inch and three quarters to three quarters of an inch.


At first, everyone agreed about the right answer. But in the third round, all the other members of the group picked the wrong line.

Surprisingly, or maybe not, most people ended up agreeing with the group when it was obviously wrong at least once in a series of rounds. And,



When asked to decide on their own, without seeing judgments form others, people erred less than 1 percent of the time. But in rounds in which group pressure supported the incorrect answer, people erred 36.8 percent of the time. Indeed, in a series of twelve questions, no less than 70 percent of people went along with the group and defied the evidence of their own senses at least once.


And, while the experiment was first conducted in America, the general pattern was fairly similar when repeated in other countries, although there were some differences.

Asch drew two conclusions. First, some people are independent most or all of the time (about 25 percent all the time and the rest not conforming 2/3 of the time. But, to quote Sunstein, "Most people, at least some of the time, are willing to yield to the group even on an apparently easy question about which they have direct and unambiguous evidence."

This is where it gets interesting. If at least one other person dissented from the group, the subject was much more likely to stick by his own observations. As Asch put it, "dissent per se increased independence and moderated the errors that occurred."

Need I say more?

TRADE, FAIR AND OTHERWISE. Although it's too soon to draw conclusions, it looks like the new Congress won't necessarily be a rubber stamp for fast track on future trade deals. Here's an interesting article on the possibilities by David Sirota on the subject.

A VOICE OF REASON ON ESTATE TAX REPEAL. This is some good news. Bill Gates Jr. of Microsoft and Gates Foundation fame, i.e. the world's richest man, came out yesterday against repealing the estate tax on those who inherit large fortunes:

WASHINGTON (MarketWatch) -- Microsoft Chairman Bill Gates, the world's richest man, said Wednesday that he agrees with his father that the elimination of the estate tax would be a bad idea. Gates' father, Bill Gates Sr., has led a campaign against efforts to repeal the tax. "I do agree with my dad, I think what he's doing there has a lot of merit," Gates told the Senate Health, Education, Labor and Pensions Committee, in response to a question from Sen. Bernard Sanders, I-Vt. Gates said he hasn't spoken out extensively on the issue because he is focused on innovation issues important to Microsoft and global health issues at the center of the Bill and Melinda Gates Foundation's mission.


GAG ORDER ON THOSE POLAR BEARS. The NY Times reports today that the Bush administration issued a memo to Fish and Wildlife personnel ordering them not to discuss climate change, sea ice or polar bears if they were not explicitly authorized to do so. This must be because polar bears hate freedom.

THE GOOD SAMARITAN EXPERIMENT, a WV alert, and privatization at Walter Reed





Caption: This man is not a terribly good man, but he might be a good Samaritan (although he'd probably rip off the victim's squeaky toys).

If El Cabrero had to pick, his favorite book of the New Testament would have to be the Gospel of Luke.

Luke is the most musical gospel. In its early chapters, people spontaneously break into beautiful songs that have become part of the liturgy of the church.

It is also primarily the gospel of and for the poor. And it contains some of the best-loved sayings and parables of Jesus.

It's the only source for the ones commonly known as the Prodigal Son, Lazarus and the Rich Man, and the Good Samaritan.

The one I'm thinking about today is the latter.

It's hard for us today to understand how baffling the words "good" and "Samaritan" would have sounded together to Jesus' Jewish contemporaries, for whom Samaritans were the lowest of the low.

It's been called "a parable of reversal," where the listener is led to think the unthinkable and say the unsayable. As John Dominic Crossan wrote in In Parables: The Challenge of the Historical Jesus, "The whole thrust of the story demands that one say what cannot be said, what is a contradiction in terms: Good+Samaritan."

The other shocker in the story was that the Samaritan's compassionate actions contrasted dramatically with the official "good guys," i.e. the priest and the Levite walked by the victim on the other side of the road.

In case you need to refresh your memory, here's the text.

The point of all this today is that this parable was actually the subject of a psychological experiment the results of which are both sad and amusing.

I quote from Frans de Waal's book Good Natured: The Origins of Right and Wrong in Humans and Other Animals:
One of my favorite experiments, by John Darley and Daniel Batson, re-created this situation with American seminary students. The students were sent to another building to give a talk about... the Good Samaritan. While in transit they passed a slumped-over person planted in an alley. The groaning "victim" sat still with eyes closed and head down. Only 40 percent of the budding theologians asked what was wrong and offered assistance. Students who had been urged to make hasted helped less than students who had been given lots of time. Indeed, some students hurrying to lecture on the quintessential helping story of our civilization literally stepped over the stranger in need, inadvertently confirming the point of the story.
You don't know whether to laugh or cry on that one...

WEST VIRGINIA ACTION ITEM. If you happen to live in El Cabrero's beloved state of West Virginia and care about education, fairness and fiscal sanity, check out the posts "Action Alert: Fighting a Corporate Giveaway" and "Tax Cuts for Big Business" at WV Blue (although the latter was written by a shady character upon whom El Cabrero may have to open a can...)

Here's the backstory...last week, the WV Senate, for reasons best known to itself, passed gazillions of dollars in corporate tax cuts with little thought of how to pay for it. Unlike the U.S. under this regime, WV has rational spending priorities, with about half of general funds going to K-12 education, 10 % going to higher ed, 20+ percent going to health and human resources, and 20+ for everything else. Cutting corporate taxes means cutting education and health care.

The Action part is to contact WV House Finance chair Harry Keith White (304-340-3230 or toll free at 1-877-565-3447) and leave the following message:


Businesses will gain little if tax cuts come at the cost of education, infrastructure and the long term well being of West Virginians. We need a responsible approach to state taxes and revenues, not careless corporate tax cuts with no plan for the future.

IT'S THE PRIVATIZATION. If you share the outrage of millions of Americans over the treatment of U.S. veterans of Iraq and Afghanistan, here's a major factor not generally covered by the big media: problems at Walter Reed and elsewhere have been made worse by the Bush administration's mania for privatization.
