Both neuroscience and social science suggest that we are more optimistic than realistic. On average, we expect things to turn out better than they wind up being. People hugely underestimate their chances of getting divorced, losing their job or being diagnosed with cancer; expect their children to be extraordinarily gifted; envision themselves achieving more than their peers; and overestimate their likely life span (sometimes by 20 years or more).
The belief that the future will be much better than the past and present is known as the optimism bias. It abides in every race, region and socioeconomic bracket. (…)
A growing body of scientific evidence points to the conclusion that optimism may be hardwired by evolution into the human brain. (…)
Scientists who study memory proposed an intriguing answer: memories are susceptible to inaccuracies partly because the neural system responsible for remembering episodes from our past might not have evolved for memory alone. Rather, the core function of the memory system could in fact be to imagine the future — to enable us to prepare for what has yet to come. The system is not designed to perfectly replay past events, the researchers claimed. It is designed to flexibly construct future scenarios in our minds. As a result, memory also ends up being a reconstructive process, and occasionally, details are deleted and others inserted.

In 1986, a young nurse named Sherri Rasmussen was murdered in Los Angeles. Police pinned down no suspects, and the case gradually went cold. It took 23 years—and revolutionary breakthroughs in forensic science—before LAPD detectives could finally assemble the pieces of the puzzle. When they did, they found themselves facing one of the unlikeliest murder suspects in the city’s history.
Have too many foreclosed properties? Why not give them away?
That’s what Bank of America plans to do with as many as 150 vacant and abandoned properties in and around Chicago through a new “collaboration” with the city that’s intended to address the problem of abandoned properties.
The psychologist Jens Rasmussen talks about three kinds of error: slips, mistakes, and violations. So, a slip is: you just do something you immediately realize wasn’t what you meant to do–pushed the wrong button, locked yourself out of your house, forgot your car keys. Mistakes are things you do because your view of the world is wrong. So, you took out a subprime mortgage and bought a house because you thought house prices would continue to rise and you would be able to remortgage your house. Then there’s a violation–something you know is against the rules but you did it anyway, for whatever reason. So, maybe you falsified your income.

According to the textbooks, our perception of size and distance is a product of how the brain interprets different visual cues, such as the size of an object on the retina and its movement across the visual field. Some researchers have claimed that our bodies also influence our perception of the world, so that the taller you are, the shorter distances appear to be. However, there has been no way of testing this hypothesis experimentally – until now.
Henrik Ehrsson and his colleagues at Karolinska Institutet have already managed to create the illusion of body-swapping with other people or mannequins. Now they have used the same techniques to create the illusion of having a very small doll-sized body or a very large, 13-foot tall body. Their results show for the first time that the size of our bodies has a profound effect on how we perceive the space around us.
Some blind people are able to use the sound of echoes to “see” where things are and to navigate their environment. Now, a new study finds that these people may even be using visual parts of their brains to process the sounds.
Echolocation is best known in bats, who send out high-pitched sounds and then use the echoes to track their prey in the dark. But a select few blind people use echolocation as well, making clicking sounds with their tongues to tell them where obstacles are. The new study, published May 25 in the open-access journal PLoS ONE, is the first to peer into the brains of blind people who are doing just that.
The study finds that in two blind men who can echolocate, brain areas normally associated with vision activate when they listen to recordings of themselves echolocating.
This is a great idea. (…) Do you own the mineral rights under your property? In many countries the government automatically owns all significant mineral deposits, no matter whose land they’re under. Here in the U.S., both the surface rights to a property and the mineral rights below can be privately owned, but they’re separable — acquiring the former doesn’t necessarily mean you’re getting the latter. (…)
If the rights are yours, you can either use them yourself or lease them to an oil company.
In Excavating Kafka, James Hawes tackles some of the myths that have built up around the writer. He suggests that Kafka is generally touted - both in ‘popular culture’ and in the worthy avenues of academe - as a gaunt, melancholy, saint-like type, staring out of blurred black-and-white photographs with anguished eyes. He was a man who ordered in his will that his works should be destroyed, who languished in obscurity throughout his lifetime, who was ‘crushed by a dead-end bureaucratic job’ and, equally, by a tyrannical father. This Kafka was an all-round seer who had no interest in the reception of his work, so preoccupied was he by his ‘Kafkaesque’ imagination. ‘These are the building blocks of the K-myth,’ writes Hawes in his introduction. ‘Unfortunately, they are all rubbish.’
Hawes, a former academic who spent 10 years studying and teaching Kafka, insists that he was not a ‘lonely Middle European Nostradamus’. Rather, he lived with his parents and was set up with a relatively cushy job (six hours a day for the equivalent of £58,000 today), leaving him plenty of time to write. Thanks to his literary connections, he won a major literary prize in his early thirties before even publishing a book. He was not tragically unrequited in his love affairs; nor was he virtually unknown in his lifetime (’we see him named three times in two entirely different articles in a single edition of the Prague Daily News in 1918′). Hawes even proposes that Kafka didn’t really want his work to be burned after his death and knew full well that the loyal Max Brod would never do it.

Villagers belonging to an Amazonian group called the Mundurucú intuitively grasp abstract geometric principles despite having no formal math education, say psychologist Véronique Izard of Université Paris Descartes and her colleagues.
Mundurucú adults and 7- to 13-year-olds demonstrate as firm an understanding of the properties of points, lines and surfaces as adults and school-age children in the United States and France, Izard’s team reports.
These results suggest two possible routes to geometric knowledge. “Either geometry is innate but doesn’t emerge until around age 7 or geometry is learned but must be acquired on the basis of general experiences with space, such as the ways our bodies move,” Izard says.
Both possibilities present puzzles, she adds. If geometry relies on an innate brain mechanism, it’s unclear how such a neural system generates abstract notions about phenomena such as infinite surfaces and why this system doesn’t fully kick in until age 7. If geometry depends on years of spatial learning, it’s not known how people transform real-world experience into abstract geometric concepts — such as lines that extend forever or perfect right angles — that a forest dweller never encounters in the natural world.
Over the years Dr Ernst and his group have run clinical trials and published over 160 meta-analyses of other studies. (Meta-analysis is a statistical technique for extracting information from lots of small trials that are not, by themselves, statistically reliable.) His findings are stark.
According to his “Guide to Complementary and Alternative Medicine”, around 95% of the treatments he and his colleagues examined—in fields as diverse as acupuncture, herbal medicine, homeopathy and reflexology—are statistically indistinguishable from placebo treatments.
In only 5% of cases was there either a clear benefit above and beyond a placebo (there is, for instance, evidence suggesting that St John’s Wort, a herbal remedy, can help with mild depression), or even just a hint that something interesting was happening to suggest that further research might be warranted.
