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

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

Fascinating and important to consider, since it is probably one of the reasons why the world aristocracy is pulling its all-out putsch right now… “Trillions will be inherited over the coming decades, further widening the wealth gap,” reports the Los Angeles Times. The beneficiaries aren’t all that young themselves. From 1989 to 2016, U.S. households inherited more than $8.5 trillion. Over that time, the average age of recipients rose by a decade to 51. More ...

Authored by Alasdair Macleod via GoldMoney.com,

Even before the coronavirus sprang upon an unprepared China the credit cycle was tipping the world into recession. The coronavirus makes an existing situation immeasurably worse, shutting down China and disrupting global supply chains to the point where large swathes of global production simply cease.

The crisis is likely to be a wake-up call for complacent investors, who are content to buy benchmark bonds i...

Gold Rallies As Fear Take Center Stage

Courtesy of Technical Traders

Gold has rallied extensively from the lows near $1560 over the past 2 weeks.  At first, this rally didn’t catch too much attention with traders, but now the rally has reached new highs above $1613 and may attempt a move above $1750 as metals continue to reflect the fear in the global markets.

We’ve been warning our friends and followers of the real potential in precious metals for many months – actually since early 2018.  Our predictive modeling system suggests Gold will rally above $1650 very quickly, then possibly stall a bit before continuing higher to target the $1750 range.

The one thing all skilled traders must consider is the longer-term fear that is build...

Precious Metals Eyeing Breakout Despite US Dollar Strength

Courtesy of Chris Kimble

Gold and silver prices have been on the rise in early 2020 as investors turn to precious metals as geopolitical concerns and news of coronavirus hit the airwaves.

The rally in gold has been impressive, with prices surging past $1600 this week (note silver is nearing $18.50).

What’s been particularly impressive about the Gold rally is that it has unfolded despite strength in the US Dollar.

In today’s chart, we look at the ratio of Gold to the US Dollar Index. As you can see, this ratio has traded in a rising channel over the past 4 years.

The Gold/US Dollar ratio is currently attempting a breakout of this rising channel at (1).
