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

The UK is widely seen as a climate leader. Its Climate Change Act, which passed into law ten years ago, is the envy of the world. It has targets for carbon reduction enshrined in law, and recently, the government hinted that it would adopt a target of zero greenhouse gas emissions by 2050 (the current target is an 80% reduction). Four years ago, the government, with cross...

"It Feels Eerily Like 2007" - DoubleLine's Gundlach Blasts Fed's "Unprecedented Reversal"

As the whipsaw in stocks and the dollar sank in today - while the bond market remains unimpressed by the machine's liftathon today - market participants are still shaking their heads at what just happened.

One of the more outspoken of those market participants is DoubleLine CEO Jeffrey Gundlach who took to Twitter this morning to express his disdain...

Interest Rates Sputter... Is U.S. Economy Next?

Courtesy of Chris Kimble.

The Federal Reserve wasn’t quite as hawkish as investors expected. The result: Treasury bond yields (interest rates) fell sharply.

In today’s chart of the 10-Year US Treasury Yield, we highlight the reversal in rates that occurred late last year.

This wasn’t just any old reversal, though. It occurred along the same long-term downtrend line that produced reversals in the years 2000 and 2007.

A closer look at the chart and it appears that 10-year yields are breaking short-term support. This is also occurring as monthly momentum rolls over fr...

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...

A good start from :

It's Not Capitalism, it's Crony Capitalism

Excerpt:

The threat to America is this: we have abandoned our core philosophy. Our first principle of this nation as a meritocracy, a free-market economy, where competition drives economic decision-making. In its place, we have allowed a malignancy to fester, a virulent pus-filled bastardized form of economics so corrosive in nature, so dangerously pestilent, that it presents an extinction-level threat to America – both the actual nation and the “idea” of America.

This all-encompassing mutant corruption saps men’s souls, crushes opportunities, and destroys economic mobility. Its a Smash & Grab system of ill-gotten re...
