We’re Often Wrong In Assessing Intention Humans are too quick to judge and to think they know what others are up to, but there are ways to correct for this.

I sometimes don't know why I do the stupid things I do. So how could I possibly know someone else's intentions? And that's the thing: We assume the intentions of others based on their actions, and our perception of their actions, and the numerous expectations and biases we hold.

You Might Not Think You’re Prejudiced… But You Probably Are Understanding your own biases (even the small ones) takes courage. How to recognize the blind spots that keep you stuck.

It's in our nature to "other" people, creating a bubble around the "in" group, and none of us avoids falling into some prejudices. That's got me digging deep to evaluate what I really think about people who are not like me. Are you brave enough to try it?

Learning to be Humble Meant Taming My Need to Stand Out How a professional crisis made this writer look inward and rethink his concept of success.

What's it mean to be humble? Probably not what you think. Humble people don't boast — that much you might've guessed. But at its core, humility requires having an accurate view of your own skills and accomplishments. But most of us don't hold accurate views of ourselves.

Marijuana Munchies Are Real, and Here’s What People Like Most Scientists were surprised by the food people chose after getting stoned. Oh, and the rats on pot? They’d eat anything.

Researchers conducted a pair of clinical trials (one on humans, one on rats) to see whether they really ate more when stoned (yes) and what they preferred to munch on. On that latter question, humans and rats differed a bit.

Abdominal fat, sometimes characterized as a beer belly, is associated with more heart damage — a thicker heart muscle and smaller heart chambers — than is excess body weight alone. The changes reflect early stress on the heart that can lead to heart disease and heart failure.

Why Some People Can’t Admit When They’re Wrong And how fessing up has significant reputational advantages, according to multiple new studies

Why won't Trump apologize for posting that blatant racist video of the Obamas? Could be one of many reasons, but in a nutshell: People who can't or won't apologize when they're blatantly wrong are known to have fragile egos or an idealized self-image that engages in self-deceit for protection.

One type of is good, and one is bad, right? Well… it's not that simple, as this scientist explains. Interesting facts: Cholesterol is made naturally by the body, and it's in every cell, but the waxy, fat-like stuff has to travel through blood in specialized bubbles, otherwise it wouldn't mix well.
