What Emotions Can Tell You

For most of human history, the emotions have been disparaged because they're so difficult to analyze-they don't come with reasons, justifications, or explanations. (As Nietzsche warned, we are often most ignorant of what is closest to us.) But now, thanks to the tools of modern neuroscience, we can see that emotions have a logic all their own. The jitters of dopamine help keep track of reality, alerting us to all those subtle patterns that we can't consciously detect. The emotional brain is especially useful at helping us make hard decisions. Its massive computational power-its ability to process millions of bits of data in parallel-ensures that you can analyze all the relevant information when assessing alternatives. Mysteries are broken down into manageable chunks, which are then translated into practical feelings.

The reason these emotions are so intelligent is that they've managed to turn mistakes into educational events. You are constantly benefiting from experience, even if you're not consciously aware of the benefits. It doesn't matter if your field of expertise is backgammon or Middle East politics, golf or computer programming: the brain always learns the same way, accumulating wisdom through error.

There are no shortcuts to this painstaking process; becoming an expert just takes time and practice. But once you've developed expertise in a particular area - once you've made the requisite mistakes - it's important to trust your emotions when making decisions in that domain. It is feelings, after all, and not the prefrontal cortex, that capture the wisdom of experience. Those subtle emotions saying shoot down the radar blip, or go all in with pocket kings, or pass to Troy Brown are the output of a brain that has learned how to read a situation. It can parse the world in practical terms, so that you know what needs to be done. When you overanalyze these expert decisions, you end up like the opera star who couldn't sing.

And yet, this doesn't mean the emotional brain should always be trusted. Sometimes it can be impulsive and short-sighted. Sometimes it can be a little too sensitive to patterns, which is why people lose so much money playing slot machines. However, the one thing you should always be doing is considering your emotions, thinking about why you're feeling what you're feeling. In other words, act like the television executive carefully analyzing the reactions of the focus group. Even when you choose to ignore your emotions, they are still a valuable source of input.

Embrace Uncertainty

Hard problems rarely have easy solutions. There is no single way to win a poker hand, and there is no guaranteed path to making money in the stock market. Pretending that the mystery has been erased results in the dangerous trap of certainty. You are so confident you're right that you neglect all the evidence that contradicts your conclusion. Of course, there's not always time to engage in a lengthy cognitive debate. When an Iraqi missile is zooming toward you or when you're about to get crushed by a blitzing linebacker, you need to act. But whenever possible, it's essential to extend the decision-making process and properly consider the argument unfolding inside your head. Bad decisions happen when that mental debate is cut short, when an artificial consensus is imposed on the neural quarrel.

There are two simple tricks to help ensure that you never let certainty interfere with your judgment. First, always entertain competing hypotheses. When you force yourself to interpret the facts through a different, perhaps uncomfortable lens, you often discover that your beliefs rest on a rather shaky foundation. For instance, when (poker player) Michael Binger is convinced that another player is bluffing, he tries to think about how the player would be acting if he wasn't bluffing. He is his own devil's advocate.

Second, continually remind yourself of what you don't know. Even the best models and theories can be undone by utterly unpredictable events. Poker players call these "bad beats," and every player has stories about the hands he lost because he got the one card he wasn't expecting. "One of the things I learned from counting cards in blackjack," Binger says, "is that even when you have an edge, and counting cards is definitely an edge, your margin is still really slim. You can't get too cocky."

When you forget that you have blind spots, that you have no idea what cards the other players are holding or how they'll behave, you're setting yourself up for a nasty surprise. Colin Powell made a number of mistakes in the run-up to the Iraq war, but his advice to his intelligence officers was psychologically astute: "Tell me what you know," he told his advisers. "Then tell me what you don't know, and only then can you tell me what you think. Always keep those three separated."

Puzzles and Positive Moods

Puzzle-solving is such an ancient, universal practice, scholars say, precisely because it depends on creative insight, on the primitive spark that ignited the first campfires. And now, modern neuroscientists are beginning to tap its source.

In a just completed study, researchers at Northwestern University found that people were more likely to solve word puzzles with sudden insight when they were amused, having just seen a short comedy routine.

“What we think is happening,” said Mark Beeman, a neuroscientist who conducted the study with Karuna Subramaniam, a graduate student, “is that the humor, this positive mood, is lowering the brain’s threshold for detecting weaker or more remote connections” to solve puzzles.

Marcel Danesi, a professor of anthropology at the University of Toronto (says) “It’s all about you, using your own mind, without any method or schema, to restore order from chaos. And once you have, you can sit back and say, ‘Hey, the rest of my life may be a disaster, but at least I have a solution.’ ”

Researchers at the University of Toronto found that the visual areas in people in positive moods picked up more background detail, even when they were instructed to block out distracting information during a computer task.

The findings fit with dozens of experiments linking positive moods to better creative problem-solving. “The implication is that positive mood engages this broad, diffuse attentional state that is both perceptual and visual,” said Dr. Anderson. “You’re not only thinking more broadly, you’re literally seeing more. The two systems are working in parallel.”
