Driven toward reward without regard for consequence

This is interesting. However, the conclusion that "individuals with antisocial personality disorder may not be unaware of… consequences… but instead that their intense reward-seeking motivation consumes their attention wholly until they have fulfilled their desire for reward" seems overstated, and only a small piece of the psychopath puzzle.

For a different perspective, that of a financial writer, and an even farther-fetched conclusion, read the second article below. The same data can be interpreted to show that a trader taking on excessive risk is "hopped up on dopamine" so they can’t see negative consequences, making them "kind of a psychopath." Take all this with a grain of salt haloperidol. - Ilene 

Driven toward reward without regard for consequence

Courtesy of TIME, by Tiffany O’Callaghan

TIMEAn overactive dopamine reward system in the brain may help explain why psychopaths pursue rewards without regard for consequences, according to new research published this week in the journal Nature Neuroscience. Previous research has found that individuals who suffer from antisocial personality disorder—often referred to as sociopathology or psychopathology, despite debate over whether these are distinct conditions—lack empathy and fear. Yet this new study, from researchers at Vanderbilt University examines what these individuals may have in excess. According to the study, led by Joshua Buckholtz, a graduate student in psychology at Vanderbilt, individuals with antisocial personality disorder traits show signs of dysfunction in dopamine reward systems—suggesting that, in psychopaths, the drive toward reward can overwhelm all else.

Prior to participating in two different experiments, study subjects completed personality tests to identify presence and severity of psychopathic characteristic—including aggression, lack of empathy, and capacity for manipulation, among other things. Drawing on previous research that has established a strong link between substance abuse and psychopathology, in the first experiment researchers gave participants amphetamine, then used functional Magentic Resonance Imaging (fMRI) brain scans to monitor how dopamine release was affected by the stimulant. In a second experiment, study participants were told that they would be paid for performing a simple task, and researchers conducted brain scans while they completed the tasks.

In both experiments, researchers found that participants who had psychopathic characteristics according to the personality test, were more likely than those without those traits to have greater activity in the nucleus accumbens, the area of the brain associated with dopamine reward processing—whether in response to the chemical stimulant, or the suggestion of monetary reward.

The findings suggest that individuals

North Korea Bailed At The Last Minute On Secret Meeting With Pence

Courtesy of Zero Hedge

Two weeks ago, followers of geopolitics couldn't help but speculate about the chances of a clandestine meeting between North Korea and the US when the news first broke that North Korean leader Kim Jong Un's younger sister, Kim Jo Yang, would be attending the Winter Games in PyeongChang.

After all, US Vice President Mike Pence was already confirmed to be stopping by South Korea during the beginning of the Games as part of a five-day Asia tour. But the White House was quick to repudiate this chatter, announcing that there were no plans for diplomatic talks, though both US and North Korean rhetoric since then has left the door open for such a meeting.

But as it turns out, just as the White House was denying it, plans for talks were being set in motion...

Sellers Come In But Semiconductors Gain

Courtesy of Declan.

Markets were set up for sellers with most indices experiencing broad selling. However, the one index which looked set up best for shorts - the Semiconductor Index - actually managed to gain.  Anyone taking up Friday's short in the latter Index will have been stopped out but another shorting opportunity may have presented itself. Technicals haven't returned to becoming net bullish but only the ADX remains to shift.


The S&P eased a little lower but didn't return below what was channel support. Te...

The tricks propagandists use to beat science

Via Jean-Luc

How propagandist beat science – they did it for the tobacco industry and now it's in favor of the energy companies:

The tricks propagandists use to beat science

The original tobacco strategy involved several lines of attack. One of these was to fund research that supported the industry and then publish only the results that fit the required narrative. “For instance, in 1954 the TIRC distributed a pamphlet entitled ‘A Scientific Perspective on the Cigarette Controversy’ to nearly 200,000 doctors, journalists, and policy-makers, in which they emphasized favorable research and questioned results supporting the contrary view,” say Weatherall and co, who call this approach biased production.

A second approach promoted independent research that happened to support ...
