In this absorbing exploration, Tali Sharot—one of the most innovative neuroscientists at work today—demonstrates that optimism may be crucial to human existence. The Optimism Bias explores how the brain generates hope and what happens when it fails; how the brains of optimists and pessimists differ; why we are terrible at predicting what will make us happy; how emotions strengthen our ability to recollect; how anticipation and dread affect us; how our optimistic illusions affect our financial, professional, and emotional decisions; and more.
People the optimism bias tali sharot to have a powerful and automatic tendency to the optimism bias tali sharot an unreasonably bright future.
Besides protecting us from stress and worry, optimism can become a self-fulfilling prophecy. Optimists act in ways that make their rosy predictions more likely to happen.

Experiments conducted on many animals, including primates, suggest optimism is a very old evolutionary adaptation. Optimism can lead to risky decisions: Tali thinks we can gain the benefits of optimism while staying realistic about risk, just by better understanding the bias.
You need to be able to imagine a better world before you can make it happen. My Thoughts The biggest surprise for me from this talk is that you can switch off parts of the brain.

People with mild depression are relatively accurate when predicting future events. They see the world as it is.

In other words, in the absence of a neural mechanism that generates unrealistic optimism, it is possible all humans would be mildly depressed. Can optimism change reality? The problem with pessimistic expectations, such as those of the clinically depressed, is that they have the power to alter the future; negative expectations shape outcomes the optimism bias tali sharot a negative way.
How do expectations change reality? To answer this question my colleague, cognitive neuroscientist Sara Bengtsson, devised an experiment in which she manipulated positive and negative expectations of students while their brains were scanned and tested their performance on cognitive tasks.
To induce expectations of success, she the optimism bias tali sharot college students with words such as smart, intelligent and clever just before asking them to perform a test.
To induce expectations of failure, she primed them with words like stupid and ignorant. The students performed better after being primed with an affirmative message.
Examining the brain-imaging data, Bengtsson found that the students' brains responded differently to the mistakes they made depending on whether they were primed with the word clever or the word stupid.
When the mistake followed positive words, she observed enhanced activity in the anterior medial part of the prefrontal cortex a region that is involved in self-reflection and recollection.
However, when the participants were primed with the word stupid, there was no heightened activity after a wrong answer.

It appears that after being primed with the word stupid, the brain expected to do poorly and did not show signs of surprise or conflict when it made an error. A the optimism bias tali sharot that doesn't expect good results lacks a signal telling it, "Take notice — wrong answer!
Expectations become self-fulfilling by altering our performance and actions, which ultimately affects what happens in the future.
Often, however, expectations simply transform the way we perceive the world without altering reality itself. Let me give you an example.
