PARIS: Neurons in the brains of liberals and conservatives fire differently when confronted with tough choices, suggesting that some political divides may be hard-wired, according to a new study.

Some previous studies have established a link between political persuasion and certain personality traits. Those who define themselves as conservatives tend to crave order and structure in their lives, and are more consistent in the way they make decisions, for example. Liberals, by contrast, show a higher tolerance for ambiguity and complexity, and adapt more easily to unexpected circumstances. [More]

Treatment of mice with a 'friendly' bacteria, normally found in the soil, altered their behavior in a way similar to that produced by antidepressant drugs, reports research published in the latest issue of Neuroscience.

These findings, identified by researchers at the University of Bristol and colleagues at University College London, aid the understanding of why an imbalance in the immune system leaves some individuals vulnerable to mood disorders like depression.

Dr Chris Lowry, lead author on the paper from Bristol University, said: "These studies help us understand how the body communicates with the brain and why a healthy immune system is important for maintaining mental health. They also leave us wondering if we shouldn't all be spending more time playing in the dirt." [More]

Dr Burnham's research budget ran to a bunch of $40 games. When there are many rounds in the ultimatum game, players learn to split the money more or less equally. But Dr Burnham was interested in a game of only one round. In this game, which the players knew in advance was final and could thus not affect future outcomes, proposers could choose only between offering the other player $25 (ie, more than half the total) or $5. Responders could accept or reject the offer as usual. Those results recorded, Dr Burnham took saliva samples from all the students and compared the testosterone levels assessed from those samples with decisions made in the one-round game.

As he describes in the Proceedings of the Royal Society, the responders who rejected a low final offer had an average testosterone level more than 50% higher than the average of those who accepted. Five of the seven men with the highest testosterone levels in the study rejected a $5 ultimate offer but only one of the 19 others made the same decision.

What Dr Burnham's result supports is a much deeper rejection of the tenets of classical economics than one based on a slight mis-evolution of negotiating skills. It backs the idea that what people really strive for is relative rather than absolute prosperity. They would rather accept less themselves than see a rival get ahead. That is likely to be particularly true in individuals with high testosterone levels, since that hormone is correlated with social dominance in many species.

Economists often refer to this sort of behaviour as irrational. In fact, it is not. It is simply, as it were, differently rational. The things that money can buy are merely means to an end—social status—that brings desirable reproductive opportunities. If another route brings that status more directly, money is irrelevant.

It has taken me years to make tentative peace with my stops and starts during work. Every morning I vow to become a morning person, starting full speed out of the gate. And every morning I daydream, shuffle papers, read e-mail messages and visit blogs, and somehow it is time for lunch. Then, at about 2 p.m., a sense of urgency kicks in, and I write steadily, until about 5 or 6, when I revert to the little-of-this, some-of-that style of the morning.

Over the years I have come to see that the hours away from the writing are the time when the real work gets done. When a paragraph turns itself this way and that in a corner of my brain even while my fingers are buying books on Amazon.com. What appears to be wasted time is really jell time. This redefinition only makes me feel a little less guilty.

Mr. Kustka assures me that the problem is not the three to four hours of concentrated work I do each day, but rather the outmoded paradigm against which I measure that work. Productivity was directly related to time back when Mr. Gilbreth was measuring things, he said, but the connection is less direct today.

“We are in a knowledge-worker world,” he says. “If you were building me a building, I could measure the number of bricks. If you were loading a truck, I could measure the number of boxes. But I can’t simply count your words. That doesn’t measure quality.” [More of an oddly comforting article]

A few companies are taking the concept of “watch what I produce, not how I produce it” even further. At the headquarters of Best Buy in Minneapolis, for instance, the hot policy of the moment is called ROWE, short for Results Only Work Environment.

There workers can come in at four or leave at noon, or head for the movies in the middle of the day, or not even show up at all. It’s the work that matters, not the method. And, not incidentally, both output and job satisfaction have jumped wherever ROWE is tried.

Several research reports, both recently published and not yet published, provide evidence of the limits of multitasking. The findings, according to neuroscientists, psychologists and management professors, suggest that many people would be wise to curb their multitasking behavior when working in an office, studying or driving a car.

These experts have some basic advice. Check e-mail messages once an hour, at most. Listening to soothing background music while studying may improve concentration. But other distractions — most songs with lyrics, instant messaging, television shows — hamper performance. Driving while talking on a cellphone, even with a hands-free headset, is a bad idea.

In short, the answer appears to lie in managing the technology, instead of merely yielding to its incessant tug. [More]
