It’s a stereotype, but many of us have made the assumption that scientists are a bit rigid and less artistic than others. Artists, on the other hand, are often seen as being less rational than the rest of us. Sometimes described as the left side of the brain versus the right side – or simply logical thinking versus artistic creativity – the two are often seen as polar opposites.
Neuroscience has already shown that everyone uses both sides of the brain when performing any task. And while certain patterns of brain activity have sometimes been linked to artistic or logical thinking, it doesn’t really explain who is good at what – and why. That’s because the exact interplay of nature and nurture is notoriously difficult to tease out. But if we put the brain aside for a while and just focus on documented ability, is there any evidence to support the logic versus art stereotype? Read More
Sprinkling “Omm” mantras between “Ooh Rah!” battle cries can pay dividends for members of the Marine Corps and other branches of the military. According to a growing body of research, regular meditation improves the wellbeing of military members — both active duty and those who have previously served.
Meditation is rooted in spirituality, which affects personal wellness in its own way, but the neurological underpinnings of meditation’s other health benefits are being widely assessed by researchers, and they’re building a scientific case for its benefits. Read More
A flurry of newspaper headlines have called into question the existence of SAD, or Seasonal Affective Disorder. Scientists, they reported, appear to have debunked a widespread conviction, that feeling low in winter time is a genuine illness caused by disturbed levels of brain chemicals and that demands treatment.
A visit to any number of Seasonal Affective Disorder (SAD) websites leads to online questionnaires offering “diagnosis”, treatment recommendations, and advertisements for light boxes – gadgets that simulate daylight and compensate for poor exposure to the real thing. SAD is identified as a form of depression caused by disturbances of hormonal rhythms sensitive to daylight, primarily melatonin. Unusually, intense exposure to artificial light often is advocated as a treatment. There is even a device that can be worn on the head, allowing the patient to use a light box on the move. Read More
Have you ever walked out of a store with a shiny new gadget and wondered, “Why did I buy this? I can’t afford it. I don’t need it. What made me buy it?” Maybe you’ve asked yourself similar questions after you broke your diet with a tempting dessert, or fell back into the arms of someone who broke your heart: “I knew I shouldn’t have done this. Why can’t I make smarter decisions?”
Neuroscientists have studied questions like these for decades, and they’ve produced a wealth of answers, as well as some tips to catch yourself in the midst of self-deception. Here are three simple ways to avoid deceiving yourself, and turn bad decisions into learning experiences. Read More
The soldiers at Checkpoint 56 ordered the woman to stop.
She was Palestinian, the soldiers were Israeli, and this checkpoint divided the Israeli and Palestinian-controlled sections of Hebron on the West Bank. The checkpoint’s metal detector had gone off when the woman walked through. The soldiers ordered her to raise her veil. She refused.
Then she pulled a knife. Read More
On November 13 2015, a series of coordinated attacks in Paris left 130 people dead. A week later, armed gunmen stormed a hotel in Mali, seizing hostages while also firing indiscriminately at guests, killing 27 people. And this week a mass shooting in San Bernardino, California, left 14 dead. While the motive is not known, the FBI has assigned counterterrorism agents to the case, sparking public speculation that the shooting may have been an act of terrorism.
You could spend hours every day watching, reading and listening to news related to these events. This level of exposure can significantly influence your worldviews and how you live your life. Read More
When Americans gather together around a table groaning with favorite dishes on the fourth Thursday of November, what are we doing beyond filling our bellies with turkey and pie? We convened four experts in the psychology of family traditions and shared meals for a roundtable discussion about what ritual means in the context of Thanksgiving. Read More
A conspiracy theory is an invitation to an exciting alternative reality where nothing is quite as it seems. There is fun to be had defying conventional wisdom, sifting through signs, uncovering lost knowledge and secret plots. But we don’t generally believe stuff just for the fun of it. For us to really believe something it has to seem plausible.
How can we be so sure that our journey off the intellectual beaten path and down twisting trails of conspiracy theory has led us to the truth, while the scientific mainstream is deluded or deceptive? Sometimes all it takes is our own overly optimistic brain telling us we understand the world in far greater depth than we actually do.
In 1907, a Massachusetts doctor named Duncan MacDougall performed an unusual series of experiments. Intrigued by the idea that the human soul had mass, and could therefore be weighed, Dr. MacDougall put together a bed fitted with a sensitive set of beam scales, and convinced a series of terminally ill patients to lie on it during the final moments of their lives.
MacDougall was nothing if not detail-oriented: He recorded not only each patient’s exact time of death, but also his or her total time on the bed, as well as any changes in weight that occurred around the moment of expiration. He even factored losses of bodily fluids like sweat and urine, and gases like oxygen and nitrogen, into his calculations. His conclusion was that the human soul weighed three-fourths of an ounce, or 21 grams. Read More
It’s probably best to get the bad news out of the way first. The so-called scientific method is a myth. That is not to say that scientists don’t do things that can be described and are unique to their fields of study. But to squeeze a diverse set of practices that span cultural anthropology, paleobotany, and theoretical physics into a handful of steps is an inevitable distortion and, to be blunt, displays a serious poverty of imagination. Easy to grasp, pocket-guide versions of the scientific method usually reduce to critical thinking, checking facts, or letting “nature speak for itself,” none of which is really all that uniquely scientific. If typical formulations were accurate, the only location true science would be taking place in would be grade-school classrooms. Read More
