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

Peter Schiff: Don't Listen To What The Fed Says; Look At What The Fed Is Doing

Via SchiffGold.com,

The Fed continues to talk tough about fighting inflation.  And the markets seem to be listening. But in his podcast, Peter Schiff said you need to look at what the Fed is actually doing. And it’s not doing much.

Despite a big rally in the stocks on Friday, the stock market finished its sixth consecutive week in the red. It’s the longest streak of consecutive losses since June of 2011.

Where Are We in the Cycle?

Where are we in the cycle? It’s a hard question to answer. Inflation is high but interest rates are low. The stock market is getting crushed but the economy is okay. When you put everything together, some pieces of the puzzle seem very out of place.

Ben and I went on Derek Thompson’s Plain English podcast to discuss all of this.

I’ll give you the bad news first. It’s over.

Some cryptocurrencies have always been fairly volatile, with values soaring or plunging within a short space of time. So for the more cautious investor, “stablecoins” were considered the sensible place to go. As the name implies, they are designed to be a steadier and safer bet.

At the moment though, that stability is proving hard to find. The value of o...

Powell doing a Volker to crush inflation, yeah right!

Courtesy of Read the Ticker

In 1979, Volker was equal to Goliath as he had a good chance of crushing inflation, today the debt Goliath is massive.

In the video below David Rosenberg explains the FED is on a 'Volker' mission to crush inflation no matter what happens to risk on assets like stocks.

David Rosenberg thinking is challenged when ask about the current US debt levels, as Paul Volker did say that he could not have crushed inflation with the debt levels of today.  David Rosenberg simply says the FED is going to hike no matter what, until something very serious breaks.

The question remains will something break in the markets after 1%, 1.5% or 2% hikes. No one knows. But as the US debt to GDP% is over 120% this suggests s...

Microstrategy is a tech company selling its enterprise software solutions and analytics (platform)… but it is better known for something else…

It’s CEO Michael Saylor is a bitcoin whale. And he has been investing significant amounts of the companies reserves in Bitcoin. He even secured a term loan using bitcoin as collateral.

So Microstrategy is a bitcoin play as much as anything else. Well, bitcoin and the cryptocurrency space has been hit hard of late, with Bitcoin falling under $30K and other crypto coins tanking.

This is also illustrated through today’s “monthly” chart of ...

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
