`True Grit` may soon be a personality trait

New research suggests that, like Marshal Cogburn (played by John Wayne), people with the true-grit trait have a perseverance and passion for long-term goals, and that they have a different physiological response when faced with challenge and adversity, the Independent reported.

‘True Grit’ fans may argue over the superiority of John Wayne’s Oscar-winning portrayal of Marshal Rooster Cogburn in 1969 and Jeff Bridges’ best-actor-nominated effort in 2011.

But one thing they’ll agree is that the hallmark of both performances is the bloody-minded determination of the larger-than-life character at the heart of both films.

So tenacious in fact, psychologists suggest that True Grit should be recognised as a distinctive personality trait, which stands apart from the averagedly determined man or woman.

New research suggests that, like Marshal Cogburn (played by John Wayne), people with the true-grit trait have a perseverance and passion for long-term goals, and that they have a different physiological response when faced with challenge and adversity, the Independent reported.

“Grit, a recently proposed personality trait associated with persistence for long-range goals, predicts success in part by promoting self-control, thus allowing people to persist in repetitive, tedious or frustrating behaviours that are necessary for success,” the researchers said. “People high in grit are more passionate about their goals and more dedicated to accomplishing them, so the importance of success should be higher for gritty people.”

Making of Europe unlocked by DNA

DNA sequenced from nearly 40 ancient skeletons has shed light on the complex prehistoric events that shaped modern European populations.


The Neolithic was a period of momentous cultural and demographic change

A study of remains from Central Europe suggests the foundations of the modern gene pool were laid down between 4,000 and 2,000 BC – in Neolithic times.

These changes were likely brought about by the rapid growth and movement of some populations.

The work by an international team is published in Nature Communications.

Decades of study of the DNA patterns of modern Europeans suggests two major events in prehistory significantly affected the continent’s genetic landscape: its initial peopling by hunter-gatherers in Palaeolithic times (35,000 years ago) and a wave of migration by Near Eastern farmers some 6,000 years ago. (in the early Neolithic)

But the extent to which present-day people are descended from the indigenous hunters versus the newcomers that arrived in the Neolithic has been a matter of some debate.

Bullying more violent in school with gangs nearby, study finds

CHAMPAIGN, Ill. — The presence of gangs in the vicinity of schools creates a pervasive climate of fear and victimization among students, teachers and administrators that escalates the level of aggression in bullying incidents and paralyzes prevention efforts, suggests a new study in the journal Psychology of Violence.

Gang presence causes incidents of victimization toward students and teachers to become more violent. And, fearing for their own safety, bystanders, teachers and administrators adopt a laissez faire attitude toward bullying that perpetuates a culture of victimization, the researchers say.

Based upon interviews with students and the researchers’ observations, the study examined the influence that gang presence is having on bullying at one middle school in the Midwest, identified by the pseudonym Thompson Middle School in the study. Thompson is located in a rural community with more than 20 gangs and 2,000 known members.

The current study was part of a larger project funded by the U.S. Centers for Disease Control and Prevention that examined links between bullying and sexual violence. Bullying expert Dorothy L. Espelage, who is an educational psychologist at the University of Illinois, led that research.

In analyzing the data for the sexual violence project, the researchers encountered several themes at Thompson Middle School that were strikingly different from the other four schools in the case study. Anjali Forber-Pratt, who was then a doctoral student and graduate researcher on the sexual violence project, decided to examine the themes at Thompson in greater depth and produced the current study, with Espelage as one of her co-authors.

B.C. researchers find link between race and disease immunity

The culmination of about two or three years of work, the study represents the tip of the iceberg when it comes to this kind of genetic research, Watson said in a telephone interview from New York, where he does postdoctoral research at Mount Sinai School of Medicine.

A team of North American scientists has cracked a particularly-complex genetic code that reveals ethnicity may determine how well a person is able to fend off diseases such as HIV or the common flu.

Five scientists from Simon Fraser University were among those who found a link between race and antibodies, the culmination of years of research that may have implications in the way doctors treat patients.

The team found certain ethnicities have missing or added DNA links, a factor that could influence immunity to certain diseases, said Corey Watson, one of the team’s 14 researchers.

A “good number” of antibody genes vary from person to person, scientists discovered, which can effect how well the genes operate and which diseases they battle.

Watson said these missing or added links may be attributable to environmental conditions or past exposure to certain pathogens, which is why certain ethnic groups combat diseases differently.

What Do Birds Do for Us?

Some might not realize the tangible value of birds, but it would be foolish to underestimate how tough life would be without them.

Odds are, if you’re reading this magazine, you feel a moral and aesthetic imperative to support bird conservation. With an estimated 1,200 species facing extinction over the next century, and many more suffering from severe habitat loss, the impulse to protect birds must be universal. Right?

Well, if you happen to be a birder or a biologist, then “of course, birds have an intrinsic value, and we have an ethical obligation to conserve them,” says University of Utah ornithologist Cagan Sekercioglu. But bird enthusiasts don’t add up to a social consensus. “A lot of people want something more utilitarian,” he points out. Elected officials face competing constituent pressures; corporate executives must answer to shareholders; working folks have more immediate economic concerns. If we want policy makers and the public to take conservation seriously, then perhaps we must offer credible research showing that healthy bird populations are essential to human welfare.

Fortunately, there’s plenty of proof. Birds keep farmers in business. They protect our drinking water by preventing erosion. They slow the spread of disease. They keep the furniture industry supplied with timber. They provide critical environmental data. The list continues ad infinitum. The collective term for the many ways birds (and other animals, plants, and landscapes) support and improve human life is “ecosystem services.” Understanding these services, and quantifying their dollar value, has been a growing priority for scientists worried about the unprecedented loss of biodiversity we’re now seeing—by one popular estimate, some 27,000 plant and animal species each year, many of them driven extinct by human activity.

Facebook ‘Likes’ reveal more about you than you think

Using a dataset of more than 58,000 U.S. Facebook users, University of Cambridge researchers predicted race, age, IQ, sexuality, personality, substance use and political views using Likes alone.

If you “Like” lots of people, places and things on Facebook, you may get rewarded with discounts and special offers. But new research out today shows that these public Likes reveal more about you than you may think.

Using a dataset of more than 58,000 Facebook users in the USA collected between 2007 and 2012, researchers at the University of Cambridge in the United Kingdom were able to accurately predict certain qualities and traits, such as race, age, IQ, sexuality, personality, substance use and political views using Facebook Likes alone.

The Likes include photos, friends’ status updates, Facebook pages of products, sports, musicians, books, restaurants or popular websites.

“Likes represent a very generic class of digital records, similar to Web search queries, Web browsing histories, and credit card purchases,” says the study in Proceedings of the National Academy of Sciences.

The participants gave researchers access to their Facebook pages and they completed a variety of online tests, including personality and IQ. Their Likes were fed into algorithms and researchers created statistical models that were able to predict the personal details using Facebook Likes alone. Results were corroborated with information from the Facebook profiles and personality tests.

Top psychiatrist: Meds behind school massacres

“We are giving drugs to children who are passing through critical development stages, and as a society we are really conducting a vast experiment and no one really knows what the outcome of that will be.”

If lawmakers and authorities are truly concerned about stopping gun violence in schools, they need to take a close look at the prescription of psychotropic drugs for children and young people, says a leading psychiatrist.

In an exclusive in-person interview in New York City with WND, London-based Dr. David Healy criticized pharmaceutical companies that have made billions of dollars marketing Selective Serotonin Reuptake Inhibitors, known as SSRIs.

Psychotropic drugs “prescribed for school children cause violent behavior,” Healy stated.

The drugs are widely used in the U.S. as antidepressants by doctors working in the mental health field and increasingly by primary care doctors, he noted.

Healey insisted the problem today is that doctors working with schools to control the behavior of children are inclined to prescribe SSRI drugs without serious consideration of adverse consequences.

“The pharmaceutical companies made these drugs with the idea of making money,” he said. “There’s a wide range of problems when it comes to looking at these drugs for children. Very few children have serious problems that warrant treatment with pills that have the risks SSRI drugs have.”

The drugs can make children “aggressive and hostile,” he noted.

The World’s Smartest Man: Chris Langan

Christopher Michael Langan (born c. 1952) is an American autodidact whose IQ was reported by 20/20 and other media sources to have been measured at between 195 and 210. Billed by some media sources as “the smartest man in America”, he rose to prominence in 1999 while working as a bouncer on Long Island. Langan has developed his own “theory of the relationship between mind and reality” which he calls the “Cognitive-Theoretic Model of the Universe (CTMU)”.

DOD Spends $100,000 Studying Whether Jesus Died for Klingons

At another DoD-funded gathering, the brainstorming sessions covered topics such as how to make deep space travel most efficient, how scientists would go about creating a “warp bubble,” and whether or not humans would need to wear clothing during space travel. This event even featured actors from the famous “Star Trek” TV series as special guests.

Senator Tom Coburn’s (R-OK) latest report on spending by the Department of Defense shows, among other things, defense spending used for lecture series involving fictional alien species.

“Did Jesus Die for Klingons too?” was just one session at a recent workshop funded by the Defense Advances Research Projects Agency:

Further, DARPA paid nearly $100,000 for a strategy planning workshop on the 100 Year Starship project last year included an interesting discussion involving the Klingons, a fictional alien species who were villains and then later allies of humanity in the Star Trek series. The session entitled “Did Jesus die for Klingons too?” featured philosophy professor Christian Weidemann of Germany’s Ruhr-University Bochum who pondered the theological conflict to Christianity if intelligent life was found on other planets.

The Psychopathology of the Liberal Mind

Those suffering from this particular psychosis, then, naturally enough, become preoccupied with seeking relief, in particular through pseudo-idealism or “celebrating” victimhood.

The ever-increasing culture of entitlement was correctly identified by Mitt Romney as a leading factor in the Democrats’ victory. However, running in parallel is another culture on the rise — one far less well-identified, which bodes ominously not only for the GOP’s future prospects, but, more importantly, for the democratic process itself.

If the culture of entitlement is illustrated by 47% of the population believing they have a right to live off the country’s teat, then what could be termed a “culture of pseudo-idealism” is the mindset that gets its self-worth from assisting them to do that.

Pseudo-idealism is a term coined by the Australian biologist Jeremy Griffith to describe apparently charitable behavior that on scrutiny is revealed as selfish, because the giver is engaging in it only so that he or she can feel good about him- or herself. It is a characteristic commonly found among the left, and it constitutes what the author Geoffrey Wheatcroft recognized as the left’s inherent dishonesty.
