Let me start with a question: How do you know if a person is lying? If you’re like most people, your first response will be something like “Liars don’t make eye contact.” In a survey of 2,520 adults in sixty-three countries, 70 percent of respondents gave that answer. People also tend to list other allegedly telltale signs of lying, such as fidgeting, nervousness and rambling. In an interview with the New York Times, psychologist Charles Bond, who studies deception, said the stereotype of what liars do “would be less puzzling if we had more reason to imagine that it was true.” It turns out that there’s no “Pinocchio effect,” no single nonverbal cue that will betray a liar. Judging a person’s honesty is not about identifying one stereotypical reveal, such as fidgeting or averted eyes. Rather, it’s about how well or poorly our multiple channels of communication — facial expressions, posture, movement, vocal qualities, speech — cooperate.

There are four simple steps to the Feynman Technique, which I’ll explain below:
- Choose a Concept
- Teach it to a Toddler
- Identify Gaps and Go Back to The Source Material
- Review and Simplify
Ever since Charles Darwin published On the Origin of Species in 1859, evolution has been the grand unifying theory of biology. Yet one of our most important biological traits, consciousness, is rarely studied in the context of evolution. Theories of consciousness come from religion, from philosophy, from cognitive science, but not so much from evolutionary biology. Maybe that’s why so few theories have been able to tackle basic questions such as: What is the adaptive value of consciousness? When did it evolve and what animals have it?
The Attention Schema Theory (AST), developed over the past five years, may be able to answer those questions. The theory suggests that consciousness arises as a solution to one of the most fundamental problems facing any nervous system: Too much information constantly flows in to be fully processed. The brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and in the AST, consciousness is the ultimate result of that evolutionary sequence. If the theory is right—and that has yet to be determined—then consciousness evolved gradually over the past half billion years and is present in a range of vertebrate species.
You make thousands of rational decisions every day — or so you think.
From what you’ll eat throughout the day to whether you should make a big career move, research suggests that there are a number of cognitive stumbling blocks that affect your behavior, and they can prevent you from acting in your own best interests.
Here, we’ve rounded up the most common biases that screw up our decision-making.
“We form our beliefs based on what comes to us from the world through the window of perception, but then those beliefs act like a lens, focusing on what they want to see. In a New York University psychology laboratory earlier this year, a group of subjects watched a 45-second video clip of a violent struggle between a police officer and an unarmed civilian.3 It was ambiguous as to whether the officer, in trying to handcuff the person resisting arrest, behaved improperly. Before seeing the video, the subjects were asked to express how much identification they felt with police officers as a group. The subjects, whose eye movements were being discretely monitored, were then asked to assign culpability. Not surprisingly, people who identified less strongly with police were more likely to call for stronger punishment. But that was only for people who often looked at the police officer during the video. For those who did not look as much at the officer, their punishment decision was the same whether they identified with police or not…”
