Milgram obedience experiment replicated

About 50 years ago Stanley Milgram conducted controversial experiments showing that seemingly normal people, when ordered by an authority figure, were willing to administer what they thought were painful electric shocks. Now the flagship journal of the American Psychology Association carries a paper claiming that Milgram’s results have been replicated.

Jerry M. Burger, PhD [at Santa Clara U.] … found that compliance rates in the replication were only slightly lower than those found by Milgram. And, like Milgram, he found no difference in the rates of obedience between men and women.

…”People learning about Milgram’s work often wonder whether results would be any different today,” said Burger, a professor at Santa Clara University. “Many point to the lessons of the Holocaust and argue that there is greater societal awareness of the dangers of blind obedience. But what I found is the same situational factors that affected obedience in Milgram’s experiments still operate today.”

Burger’s participants were 29 men and 41 women. His experiment was done in 2007 but the results have just been officially published. Milgram’s experiments showed that 79% of participants would administer “shocks” even after their “victims” protested; Burger found an obedience rate of 70%.

"Hypermusic Prologue: A projective opera in seven planes"

warped passages I like to post here (and yes, I do still post here, despite my occasional protracted absences…darn deadlines!) about those odd occasions when the theatrical world intersects with the science fictional or the scientific. But I don’t think I’ve ever run across anything quite like this: Lisa Randall, a theoretical physicist in Harvard’s Department of Physics, is writing an opera. (Via IdeaFestival.)

Randall is the author of a 2005 book called Warped Passages that, in the word of Samuel P. Jacobs, writing for the Boston Globe, “introduced nonscientific readers to the possibility of additional dimensions beyond the three we see, and how their existence could account for many of the physical world’s most perplexing phenomena.”

In response to that book Spanish composer Hector Parra, asked Randall if she would try writing a libretto for an opera about her work. Jacobs writes:

The resulting piece, a collaboration with the artist Matthew Ritchie, is scheduled to debut in Paris at the Georges Pompidou Centre this summer, then travel throughout Europe in the fall.

The opera is an intimate work – an hourlong show written for two performers – that carries uncomfortable ideas about our world and how we experience it. The piece has the puzzling title of “Hypermusic Prologue: A projective opera in seven planes,” the seven planes referring to space and to the opera’s seven acts. The work’s broader goal is to suggest new approaches to both science and art. The old-fashioned form of opera, Randall and her colleagues hope, can become a vehicle for modern science, using sound and voice to re-create the many dimensions that physicists now explore.

“It’s kind of mathematical, it is geometrical, and it is looking towards the future,” Randall, 46, says of the title.

And if anyone actually sees the opera, let us know what you think!

Only the smart die young

You’d probably think that intelligence would be an asset in the modern battlefield, and hence the smart soldiers would be the ones to survive, right?

Well, as logical as that sounds it may not be the case: a study of records from Scottish army units from WW2 and from the education system about a decade before suggests that the average IQ of those who survived the war was lower than those who lost their lives.

Down the co-op: wind farms in the UK

Good news on the alternative energy front: researcher Baidya Roy has found solutions to some problems with wind energy. There’s also an article here on wind-farm co-operatives in the UK:

The cooperative, which began production in March, is the first wind farm to be wholly owned by individuals in Britain, which with gales sweeping in from the Atlantic has the best wind resources in Europe.

“We have produced energy every day since then,” Adam Twine, a farmer who started the project 15 years ago on his plot of land by installing five wind turbines 49 metres (160 feet) in height.

Overall, the project cost eight million pounds (8.9 million euros, 11.9 million dollars), nearly 60 percent of which came from individual shareholders, with the remainder being funded by a bank loan that is to be repaid over the next eight to 10 years.

CO2 emissions resulting from the production, installation and the lifetime of the turbine, which stretches 25 years, will be offset in just six months.

This is quite a heartening story: it combines the best elements of top-down (government subsidy) and bottom-up (locally-owned co-operative organisation) energy solutions.

Space shuttles for sale – $42million o.n.o.

Also, you’ll need to ally yourself with the right sort of organisation: a science museum, perhaps, or a university. NASA won’t sell them to any old interested party with $42 million in used banknotes, you see… or at least, that’s the plan at the moment while they scout for potential buyers. If there aren’t many interested parties, maybe your independent bid will be taken more seriously.

So why not go for it? The buying price includes the cost of stripping out all the toxic and hazardous materials, as well as flying it to a US airport of your choice – worry-free bargains like this are one of the upsides to the economic slump, I guess.
