How Statistics Fool Juries | Mental Floss - 0 views

  • While my experience wasn't related to statistics, it was an issue of science which seemed like we should have been able to prove the right answer one way or another -- but we failed.

People With Flexible Work Schedules Work Longer Hours | Mental Floss - 0 views

  • Being able to choose when and where you work is a luxury, but it comes with a price, as new research shows. Having more autonomy in your work often means working longer hours, even when controlling for seniority and different job types.

Is Your Mobile Phone Use Bad for Your Mental Health? | Mental Floss - 0 views

  • Smartphones, those digital portals of constant information, have become so integrated into most Americans’ lives, they’re like extra—yet essential—appendages. Some 72 percent of Americans own a smartphone, compared to the global median of 43 percent. But studies have shown that overuse can have a negative impact on your posture, eyesight, and hearing, not to mention distract drivers and pedestrians. More recently, researchers who study the relationship of mobile phone use and mental health have also found that excessive or “maladaptive” use of our phones may be leading to greater incidences of depression and anxiety in users.
  • Cell phones, and smartphones in particular, have an undeniably addictive quality, earning an entry in the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5th edition. A review of literature on cell phone addiction, published in Frontiers in Psychiatry, describes cell phone and technology addiction manifesting in one or more of the following ways: choosing to use your device even in "dangerous or prohibited contexts;" losing interest in other activities; feeling irritable or uneasy if separated from your phone; or feeling anxiety or loneliness when you’re unable to send or receive an immediate message. The researchers also find that adolescents and women may be more susceptible to this behavioral addiction.
  • So while the research remains inconclusive, it might be worth taking a look at how you feel before and after you spend copious amounts of time on your cell phone. It may be harmless—or it may offer an opportunity to improve your mental health.

Why Coloring and Doodling Make Us Feel Good | Mental Floss - 0 views

  • there was a neurological basis for the relaxation-inducing powers of coloring, doodling, and drawing
  • All three activities produced an increase in blood flow to the prefrontal cortex, a region that plays a central part in the brain’s reward system. During rest periods, blood flow slowed until it reached normal resting rates.
  • Sometimes, we tend to be very critical of what we do because we have internalized, societal judgments of what is good or bad art and, therefore, who is skilled and who is not," she said. "We might be reducing or neglecting a simple potential source of rewards perceived by the brain. And this biological proof could potentially challenge some of our assumptions about ourselves

Why We Keep Falling for Fake News | Mental Floss - 0 views

  • Some studies have found that viral ideas arise at the intersection of busy social networks and limited attention spans. In a perfect world, only factually accurate, carefully reported and fact-checked stories would go viral. But that isn’t necessarily the case. Misinformation and hoaxes spread across the internet, and especially social media, like a forest fire in dry season.
  • Within the model, a successful viral story required two elements: a network already flooded with information, and users' limited attention spans. The more bot posts in a network, the more users were overwhelmed, and the more likely it was that fake news would spread.
  • One way to increase the discriminative power of online social media would be to reduce information load by limiting the number of posts in the system," they say. "Currently, bot accounts controlled by software make up a significant portion of online profiles, and many of them flood social media with high volumes of low-quality information to manipulate public discourse. By aggressively curbing this kind of abuse, social media platforms could improve the overall quality of information to which we are exposed

If You've Ever Seen a Ghost, Science May Explain Why | Mental Floss - 0 views

  • Despite all the reports of ghost sightings (28 percent of Americans report having ghostly encounters), there’s zero evidence to support the presence of supernatural beings among us. Science may not prove the existence of ghosts, but it can help explain why people think they see ghosts in the first place.

Experts Say Trying to Force Yourself to Be Happy Doesn't Work | Mental Floss - 0 views

  • "Maybe if you have an accepting attitude toward negative emotions, you're not giving them as much attention," Mauss said. "And perhaps, if you're constantly judging your emotions, the negativity can pile up."

Are Smart People More Likely to Believe Stereotypes? | Mental Floss - 0 views

  • There are many different kinds of intelligence, each reliant on its own set of skills and abilities. One such ability is pattern recognition, without which we’d have trouble recognizing faces, learning languages, or reading other people’s emotions. Because it’s so central to our cognitive and social functioning, pattern recognition is sometimes used by researchers as a shorthand for overall intelligence.
  • Finding that higher pattern detection ability puts people at greater risk to detect and apply stereotypes, but also to reverse them, implicates this ability as a cognitive mechanism underlying stereotyping,” co-author Jonathan Freeman said in the statement.

'The Man Who Knew Infinity' Explores Faith And Mathematics - 0 views

  • Applied mathematical knowledge was also downplayed. Hardy's circle rejected Isaac Newton's emphasis on empirical testing of mathematical hypothesis and also rejected the European emphasis on using math for human betterment. Math, for Hardy's group, was not supposed to be applicable or useful for the masses. It was there for one purpose only: for the enjoyment of the few truly great minds who could understand and appreciate it. Hardy bragged that none of his mathematical work had been of any use to humanity, saying , "I have never done anything 'useful'. No discovery of mine has made, or is likely to make, directly or indirectly, for good or ill, the least difference to the amenity of the world."

Ask Ethan: Where Is The Line Between Mathematics And Physics? - 0 views

  • What, then, are you supposed to do when the mathematics gets more abstract? What do you do when you get to General Relativity, or Quantum Field Theory, or even more far afield into the speculative realms of cosmic inflation, extra dimensions, grand unified theories, or string theory? The mathematical structures that you build to describe these possibilities simply are what they are; on their own, they won't offer you any physical insights. But if you can pull out either observable quantities, or connections to physically observable quantities, that's when you start crossing over into something that you can test and observe.
  • Now, string theory (or, more accurately, string theories) have their own constraints governing them, as do the forces in our Universe, so it isn't provably clear that there's a one-to-one correspondence between our four-dimensional Universe with gravity, electromagnetism, and the nuclear forces and any version of string theory. It's an interesting conjecture, and it has found some applications to the real world: in the study of quark-gluon plasmas. In that sense, it's more than mathematics: it's physics. But where it strays from physics into pure mathematics is not yet fully determined.
  • If you describe the Universe precisely, and you can make quantitative predictions about it, you're physics. If those predictions turn out to be accurate and reflective of reality, then you're physics that's correct and useful. If those predictions are demonstrably wrong, you're physics that doesn't describe our Universe: you're a failed attempt at a physical theory. But if your equations have no connection at all to the physical Universe, and cannot be related to anything you can ever hope to someday observe or measure, you're firmly in the realm of mathematics; the divorce from physics will then be final. Mathematics is the language we use to describe physics, but not everything mathematical is physically meaningful. The connection, and where it breaks down, can only be determined by looking at the Universe itself.

The Logical Fallacy Of Security Predictions - 0 views

  • There has been a persistent logical fallacy that annual security predictions will somehow help us to prognosticate our way to a clearer understanding of the security landscape ahead. These predictions often revolve around “budgets will increase by “$arbitrary percentage points”.

Reaganomics Vs. Obamanomics: Fallacies Offered By The Left - 1 views

  • From watching and participating in debates over the years regarding Reaganomics, patterns of logical fallacies and factual errors repeatedly arise among critics on the Left.  As the troublesome facts demonstrating the failures of Obamanomics accumulate, we find that almost religiously minded supporters of President Barack Obama can't deal with those facts, and exhibit analogous logical fallacies.
  • Some critics falsely argue that Reagan increased payroll taxes which are paid much more by lower and moderate income workers.  The payroll tax rate increases of the 1980s were adopted under President Carter and the Democratic Congress in 1977.  The Greenspan Commission Social Security rescue plan adopted in 1983 only advanced a couple of these already scheduled payroll tax rate increases by a year or two.  But the ultimate plan for payroll taxes is to phase them out entirely in favor of lower cost personal accounts to finance the benefits currently financed by those taxes, as discussed in previous columns in this space.

How To Bolster Your Negotiations With Informal Fallacies - 0 views

  • An informal fallacy is an attempt at making a logical argument where there’s a failure in the reasoning itself. This can stem from a number of causes, such as the misapplication of words and phrases, or misunderstandings based on inappropriate assumptions. Illogical sequences in an argument can also cause informal fallacies. While informal fallacies can result in inaccurate arguments and false conclusions, that doesn’t mean they can’t be very persuasive.
  • When negotiating, for instance, it’s fairly common for self-made millionaires to employ informal fallacies. Many self-made millionaires develop well-defined plans on how they’ll use informal fallacies as part of their preparation as well as regularly incorporate these fallacies into verbal dueling with adversaries.
  • Confusing causality for correlation: You connect events that happened at the same time or one after another even though one need not have caused the other.
  • ...1 more annotation...
  • Self-made millionaires also rarely want the success of their deal making to hang on informal fallacies. Instead, they use informal fallacies to accentuate and strengthen pieces of their argument. Using informal fallacies this way makes sure that if they don’t get the desired reaction from negotiating adversaries, they can be easily discarded in favor of new proofs.
