Why Some Learn Faster Than Others

Education isn't magic. It is the wisdom wrung from failure. People learn how to get it right by getting it wrong again and again. But why do some people learn faster than others?

What's the Latest Development?

A new study published in Psychological Science sheds light on why some people learn quicker from their mistakes than others. Each time we make a mistake, the brain reacts twice. The first reaction, error-related negativity, appears just 50 milliseconds after the mistake; the second, error positivity, occurs later and is associated with awareness of the mistake. While these reactions occur involuntarily, they are influenced by what people believe to be the true nature of intelligence.

What's the Big Idea?

In the recent study, people were divided into two groups: One that thought of intelligence as a fixed characteristic and another that thought it was more malleable. Following their outlook on intelligence, mistakes made during the experiment either represented an immutable failure or a chance to learn and improve. Those who viewed intelligence as the product of a learning process, rather than purely as talent, had longer error positivity reactions indicating they were more attentive to—and more willing to correct—their mistakes. 

Why a federal judge ordered White House to restore Jim Acosta's press badge

A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

  • The new definition of a kilogram is based on a physical constant in quantum physics.
  • Unlike the current definition of a kilogram, this measurement will never change.
  • Scientists also voted to update the definitions of several other measurements in physics.
