Telegraph | News | Why dithering gets you nowhere

Trust your gut instincts when decision-making gets tough, a study published today suggests.

The research, published in the journal Current Biology, shows that, in some cases, snap decisions are more reliable than endless pondering using higher-level cognitive processes.

Participants were asked to pick the odd one out on a screen covered in more than 650 identical symbols, including one rotated version of the same symbol.

They performed better when given no time to linger and were forced to rely on their subconscious.

Dr Li Zhaoping, of University College London, said: "You would expect people to make more accurate decisions when given the time to look properly.

"The conscious or top-level function of the brain, when active, vetoes our initial subconscious decision — even when it is correct – leaving us unaware or distrustful of our instincts and at an immediate disadvantage.

"Falling back on our inbuilt, involuntary subconscious processes for certain tasks is actually more effective than using our higher-level cognitive functions.

"Participants would have improved their performance if they had been able to switch off their higher-level cognition by, for example, acting quickly."

The work chimes with an earlier study showing that novice artists draw better portraits if their subject is shown upside down, so they are not distracted by whose face it is and other "higher level" information and focus on details instead.

It also backs a study of decision-making based on two categories, complex, like buying a house or car, and simple, like choosing a shampoo.

Researchers at the University of Amsterdam found that thinking hard about what car you should choose leads you to make a poor choice, certainly not the best one.

People identified the best car of four, each with 12 desirable attributes, around 25 per cent of the time, which was no better than chance.

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the...

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking ...

BBC NEWS | Technology | The ethical dilemmas of robotics

BBC NEWS | Technology | The ethical dilemmas of robotics If robots can feel pain, should they be granted certain rights? If robots develop emotions, as some experts think they will, should they be allowed to marry humans? Should they be allowed to own property? These questions might sound far-fetched, but debates over animal rights would have seemed equally far-fetched to many people just a few decades ago. Now, however, such questions are part of mainstream public debate. And the technology is progressing so fast that it is probably wise to start addressing the issues now. One area of robotics that raises some difficult ethical questions, and which is already developing rapidly, is the field of emotional robotics. More pressing moral questions are already being raised by the increasing use of robots in the military This is the attempt to endow robots with the ability to recognise human expressions of emotion, and to engage in behaviour that humans readily perceive as emotional.
