Stupid People Are Surprisingly Confident (video)

If you’re like most people, you can admit you’re quite good at some things — and not so good at others. But as our host Ben Bowlin explains in the BrainStuff video above, some people are confident in their abilities, even when that confidence is way, way off the mark. It’s known as illusory superiority, a cognitive bias in which people rate their own abilities as above average.

A newly drawn Tree of Life reminds us to question what we know

A newly drawn Tree of Life reminds us to question what we know

A newly released diagram of all life on Earth, the Tree of Life, contains a whole new branch, full of microbes — which appear to dominate Earth’s biodiversity. How did we miss this? Since Darwin’s day, scientists have worked to map all of life on a single tree to show how all forms of life on Earth evolved and are related. The DNA sequencing revolution has allowed us to fill in more of the blanks than ever before, greatly accelerating research into biodiversity and Earth’s ecosystems and constantly changing our understanding of life….

How to Overcome Procrastination By Way of Introspective Awareness

Below are McClafferty’s solutions, summarized. For more, I’d recommend reading his entire piece (linked again below): 1. Forgo the brain buffet: “Digesting multiple sources of information is difficult,” says McClafferty. It’s easy to become overwhelmed and disheartened when trying to imbibe too much info at once. Instead, take things one step at a time. Read one book. Take notes. Read the next. Take notes. Rinse.

Infographic: The Key to a Healthy Brain Is a Healthy Digestive System

You may remember a few months ago we featured a very nifty infographiccovering the basic tenets of one of our favorite topics: neuroplasticity. Some of the same folks who put that image together have created another helpful visual for understanding the fascinating link between mind and body. This time the topic is “Healthy Gut, Healthy Mind.” The basic gist: There’s a keen physiological link between the brain and digestive system. Here’s how Dr. Helene M. Savignac, an expert in neuropsychology, cognitive, and behavioral science, explains it:

How To Make $71 Billion A Year: Tax the Churches

While the desire to tax churches is not new, it seems as far from reality as possible at this moment. As has been commented, no atheist could possibly hope to win an election in today’s political climate—a freethinking man like Robert Ingersoll would have no influence with the majority of our electorate. Our cultural dependency on the necessity of faith is affecting our society: According to a University of Tampa study, not taxing churches is taking an estimated $71 billion from our economy every year, and this fact remains largely…

10 Questions That Science Can’t Answer Yet

10 Questions That Science Can’t Answer Yet

When the Black Death ran rampant through cities in the Middle Ages, no one knew exactly how or why the awful disease spread. After many generations, we figured out that rat fleas and bacteria were to blame. It was a watershed moment for the power of science. Centuries later, science continues to investigate difficult, bewildering questions every day. Yet even with brilliant minds converging via a worldwide computer network, we still don’t have all of the answers. In fact, some people might argue that we’re just now learning to ask…

10 Outrageous Experiments Conducted on Humans

Prisoners, the disabled, the physically and mentally sick, the poor — these are all groups once considered fair game to use as subjects in your research experiments. And if you didn’t want to get permission, you didn’t have to, and many doctors and researchers conducted their experiments on people who were unwilling to participate or who were unknowingly participating.
