"Humans are storytelling machines. We don't passively perceive the world - we tell stories about it, translating the helter-skelter of events into tidy narratives. This is often a helpful habit, helping us make sense of mistakes, consider counterfactuals and extract a sense of meaning from the randomness of life. But our love of stories comes with a serious side-effect: like all good narrators, we tend to forsake the facts when they interfere with the plot. We're so addicted to the anecdote that we let the truth slip away until, eventually, those stories we tell again and again become exercises in pure fiction. Just the other day I learned that one of my cherished childhood tales - the time my older brother put hot peppers in my Chinese food while I was in the bathroom, thus scorching my young tongue - actually happened to my little sister. I'd stolen her trauma. The reason we're such consummate bullshitters is simple: we bullshit for each other. We tweak our stories so that they become better stories. We bend the facts so that the facts appeal to the group. Because we are social animals, our memory of the past is constantly being revised to fit social pressures. The power of this phenomenon was demonstrated in a new Science paper by Micah Edelson, Tali Sharot, Raymond Dolan and Yadin Dudai. The neuroscientists were interested in how the opinion of other people can alter our personal memories, even over a relatively short period of time. The experiment itself was straightforward. A few dozen people watched an eyewitness style documentary about a police arrest in groups of five. Three days later, the subjects returned to the lab and completed a memory test about the documentary. Four days after that, they were brought back once again and asked a variety of questions about the short movie while inside a brain scanner. This time, though, the subjects were given a "lifeline": they were shown the answers given by other people in their film-viewing g

"Acousticians have been designing concert halls for more than a century, but Dr. Kyriakakis does something different. He shapes the sound of music to conform to the space in which it is played. The goal is what Dr. Kyriakakis calls the "ground truth" - to replicate the original in every respect. "We remove the room," he said, "so the ground truth can be delivered." Dr. Kyriakakis, an electrical engineer at U.S.C. and the founder and chief technical officer of Audyssey Laboratories, a Los Angeles-based audio firm, could not achieve his results without modern sound filters and digital microprocessors. But the basis of his technique is rooted in the science of psychoacoustics, the study of sound perception by the human auditory system. "It's about the human ear and the human brain, and understanding how the human ear perceives sound," Dr. Kyriakakis said. Psychoacoustics has become an invaluable tool in designing hearing aids and cochlear implants, and in the study of hearing generally. "Psychoacoustics is fundamental," said Andrew J. Oxenham, a psychologist and hearing expert at the University of Minnesota. "You need to know how the normally functioning auditory system works - how sound relates to human perception." "

"SOLITUDE is out of fashion. Our companies, our schools and our culture are in thrall to an idea I call the New Groupthink, which holds that creativity and achievement come from an oddly gregarious place. Most of us now work in teams, in offices without walls, for managers who prize people skills above all. Lone geniuses are out. Collaboration is in.

Research strongly suggests that people are more creative when they enjoy privacy and freedom from interruption. And the most spectacularly creative people in many fields are often introverted, according to studies by the psychologists Mihaly Csikszentmihalyi and Gregory Feist. They're extroverted enough to exchange and advance ideas, but see themselves as independent and individualistic. They're not joiners by nature"
