But here is the real challenge: How can we learn to recognize our own ignorance and misbeliefs? To begin with, imagine that you are part of a small group that needs to make a decision about some matter of importance. Behavioral scientists often recommend that small groups appoint someone to serve as a devil’s advocate—a person whose job is to question and criticize the group’s logic. While this approach can prolong group discussions, irritate the group, and be uncomfortable, the decisions that groups ultimately reach are usually more accurate and more solidly grounded than they otherwise would be.
For individuals, the trick is to be your own devil’s advocate: to think through how your favored conclusions might be misguided; to ask yourself how you might be wrong, or how things might turn out differently from what you expect. It helps to try practicing what the psychologist Charles Lord calls “considering the opposite.” To do this, I often imagine myself in a future in which I have turned out to be wrong in a decision, and then consider what the likeliest path was that led to my failure. And lastly: Seek advice. Other people may have their own misbeliefs, but a discussion can often be sufficient to rid a serious person of his or her most egregious misconceptions.

This is not to say that skill doesn’t matter — merely that in a competition in which all the leaders are highly skilled, randomness may explain the difference between triumph and failure. Good luck plus skill beats bad luck plus skill any time.

The reason why purple and violet look similar to us is because they stimulate our cones in a similar way, but most other animals don’t share the same types of cones and “post-processing”. This means that to other animals, purple and violet may look completely different!
Now imagine a violet flower petal with a purple pattern on it. Depending on the particular shades, this pattern might be completely invisible to us, while many other animals could see it as clearly as we can see an orange pattern on green background.

It’s especially important that kids get bored — and be allowed to stay bored — when they’re young. That it not be considered “a problem” to be avoided or eradicated by the higher-ups, but instead something kids grapple with on their own.
We’ve stopped training children to do this. Rather than teach them to absorb material that is slower, duller and decidedly two-dimensional, like a lot of worthwhile information is, schools cave in to what they say children expect: fun. Teachers spend more time concocting ways to “engage” students through visuals and “interactive learning” (read: screens, games) tailored to their Candy Crushed attention spans. Kids won’t listen to long lectures, goes the argument, so it’s on us to serve up learning in easier-to-swallow portions.
We need to have a lot of difficult conversations in order to resolve the issues we are facing as a society, and the only way these conversations will be productive and enduring is if we all can agree on the facts. Right now, with Americans believing more than 40 percent of the news they see is fake, we aren’t quite there as a society, but that doesn’t mean we can’t be. The internet is an amazing tool, but to use it most effectively we have to embrace its benefits while also understanding the ways in which it makes us vulnerable. If students are still learning dated practices such as cursive writing in school, shouldn’t they be learning how to navigate and consume the internet responsibly as well?
Much misinformation and many falsehoods related to politics circulate online. This paper investigates how youth judge the accuracy of truth claims tied to controversial public issues. In an experiment embedded within a nationally representative survey of youth ages 15-27 (N=2,101), we examined factors that influenced youth judgements regarding the accuracy of the content. Consistent with research on motivated reasoning, youth assessments depended on a) the alignment of the claim with their prior policy position and, to a lesser extent, on b) whether the post included an inaccurate statement. However, and most importantly, among those participants who reported the most media literacy learning experiences, there was a large, statistically significant difference in ratings of accuracy between those exposed to a post that employed misinformation and those who saw an evidence-based post. Implications for educators and policymakers are discussed.

Most people are familiar with white noise, that static sound of an air conditioner that lulls us to sleep by drowning out any background noise.
Except technically, the whirl of a fan or hum of the AC isn’t white noise at all. Many of the sounds we associate with white noise are actually pink noise, or brown, or green, or blue. In audio engineering, there’s a whole rainbow of noise colors, each with its own unique properties, that are used to produce music, help relaxation, and describe natural rhythms like the human heartbeat. If you know what to look for, you can start to notice the colors of the noise that make up the soundscape around us.

In contrast to previous assumptions, the learning process leads to a reorganization that extends to deep brain structures in the thalamus and the brainstem. The relatively young phenomenon of human writing, therefore, changes brain regions that are very old in evolutionary terms and already core parts of mice and other mammalian brains.
Researchers at Curtin University in Australia observed 20 participants working at standing desks for two hours.
They found discomfort “significantly” increased for the lower back and lower limb regions, which correlates with previous research suggesting standing desk is responsible for swelling of the veins, which can endanger the heart.
Mental reactiveness also slowed down after roughly an hour and a quarter, however “creative” decision making was shown to marginally improve.

"Leadership is hard; it needs discipline, concentration, and an ability to ignore what's irrelevant or needless or personal or silly," Pullum says. "There is no sign of it from Trump. This man talks honestly enough that you can see what he's like: He's an undisciplined narcissist who craves power but doesn't have the intellectual capacity to exercise it wisely."
