The Edmonton Journal reports: Recently, researchers asked more than 2,000 American and European adults their thoughts about genetically modified foods. They also asked them how much they thought they understood about GM foods, and a series of 15 true-false questions to test how much they actually knew about genetics and science in general. The researchers were interested in studying a perverse human phenomenon: People tend to be lousy judges of how much they know. Across four studies conducted in three countries -- the U.S., France and Germany -- the researchers found that extreme opponents of genetically modified foods "display a lack of insight into how much they know." They know the least, but think they know the most. "The less people know," the authors conclude, "the more opposed they are to the scientific consensus."

Science communicators have made concerted efforts to educate the public with an eye to bringing their attitudes in line with the experts," they write in the journal Nature Human Behaviour. But people with an inflated sense of what they actually know -- and most in need of education -- are also the ones least likely to be open to new information.... Extreme views often come along with not appreciating the complexity of the subject -- "not realizing how much there is to know," said Philip Fernbach, lead author of the new study and a professor of marketing at the University of Colorado Boulder. "People who don't know very much think they know a lot, and that is the basis for their extreme views."
Slashdot reader Layzej links to Rational Wiki's article on "The Backfire Effect," to illustrate Fernbach's observation that "People double down on their 'counter-scientific consensus attitudes'.

"Epecially when people feel threatened or if they are being treated as if they are stupid."

An anonymous reader writes "David Reese provides an interesting analysis of just how far Canada's new anti-spam legislation goes, and its implications for business. This may provide a valuable template for citizens of other countries, and may also encourage Canadians to prepare for the inevitable push-back from spammers. It is not clear from this analysis whether the legislation would affect telemarketing, but even if it does not it provides a useful precedent for future regulation in that area."

New Jazari writes "Careful what you say when traveling, since the authorities will soon be able to zoom in on your conversations and record them for an indefinite amount of time. The story is about Canada, but I see no reason to think that this capability will not soon be installed in most places (if it's not already)."

There are a few questions that you never want to hear. Do you know how to make a tourniquet? And who gave the gorilla a knife? Unfortunately for the Calgary Zoo staff, they had to answer the latter. Zoo visitors were shocked to see a gorilla holding a knife and pointing it at a fellow gorilla. "He grabbed the knife exactly in the correct position and he smelled it and looked at it. A few seconds later, another gorilla came and he was very interested. He tried to get the knife, but the gorilla with the knife lifted the knife for his buddy....It seems to me that the gorilla with the knife was a little bit angry, and he lifted his hand with the knife. It was just a scene from a crime," said Calgarian Joe Scheffler, who was at the zoo with his wife.

generica1 writes "The Edmonton Journal is reporting on the University of Alberta's National Institute for Nanotechnology's recent invention of a new method to produce quantum dots — what are currently the world's smallest quantum dots, possibly allowing for startling increases in the efficiency of semiconductor-based equipment. 'Roughly speaking, we predict there could be a 1,000-time reduction in power consumption with electronic computers built in this new way,' said Robert Wolkow, a physicist at the University of Alberta and leader of the team behind the breakthrough. Read the article for a description of the wave-like phenomenon employed by Wolkow's team to accomplish a vastly lower power consumption during the transfer of electrons."
