How is the expected utility theory used to predict human behavior? Expected utility theory is a theory of how people make choices and take risks when they don’t know the outcome. Traditional expected utility theory asserts that people are rational agents that calculate the utility of each situation and make the optimum choice each time. We’ll look at how expected utility theory for decision making works and cover some of its flaws.
Why do we fear losses more than we value gains, or obsess over unlikely disasters while downplaying probable success? Psychologist Daniel Kahneman’s prospect theory reveals that emotions—not pure logic—drive most of our choices. Prospect theory explains how we evaluate options based on reference points rather than absolutes, why proportional changes matter more than fixed amounts, and why loss aversion shapes our behavior more powerfully than any potential reward. Learn more about how understanding prospect theory can help you recognize emotional biases in your own decision-making and make more intentional choices.
What did Daniel Kahneman discover about happiness? The Nobel Prize-winning psychologist identified two distinct aspects of how we experience and evaluate happiness: the experiencing self, which lives moment-to-moment, and the remembering self, which reflects on past events. These two selves often conflict, leading us to make poor decisions about our well-being. Kahneman’s research in Thinking, Fast and Slow reveals that we tend to heavily favor the remembering self when making choices, often at the expense of moment-to-moment contentment. Read more to learn how both selves can help you make better decisions and achieve lasting happiness.
Why do we make decisions that cause us to suffer? The answer lies in the remembering self—the part of your mind that recalls past experiences and uses those memories to guide future choices. This mental system prioritizes memorable moments over actual lived experience, often distorting your judgment in ways you don’t realize. This concept, explored in depth through Daniel Kahneman’s research in Thinking, Fast and Slow, explains three critical flaws: how we endure needless suffering for memorable endings, how our current focus warps our evaluation of overall happiness, and how we consistently misjudge what will make us happy in the
When faced with difficult decisions, most of us fall into the same trap: We choose the least bad option from whatever alternatives we’re given, then wonder why we’re still not satisfied with the outcome. But what if there were a way to create better options rather than simply choosing between existing ones? In their book Creating Great Choices, Jennifer Riel and Roger L. Martin explore what integrative thinking is and how it differs from conventional decision-making approaches. They also examine why our usual methods of making tough choices often fail us, creating the problems that integrative thinking is designed to
How do some investors consistently beat the markets, make billions, and manage to maintain a sense of calm? How can we emulate them to achieve wealth and keep our stress levels in check?

Why do we fall in love, feel jealous, compete for status, or sacrifice for family? Robert Wright’s The Moral Animal offers a theory: These behaviors are hardwired into us by evolution. Published in 1994, this book connects biology, anthropology, and psychology in an attempt to explain everything from romantic attraction to moral judgment. Keep reading to see how understanding our evolutionary programming might help us make sense of our own motivations and better understand the people around us.
Why do brilliant people sometimes make the most foolish decisions?

Keep reading for a full overview of the book.
If you’ve ever felt your stomach turn in a moment of anxiety or felt like jumping up and down with excitement, then you’ve experienced the mind-body connection firsthand. Ellen Langer’s The Mindful Body argues that you can use this connection to take control of your health. We’ll explore Langer’s assertion that the mind and body are inextricable and discuss how this link manifests in health outcomes.

Finally, we’ll touch on two research-backed strategies for approaching your health mindfully. Continue reading for our
How do you know the world you see around you is real? It’s not, according to neuroscientist and entrepreneur Beau Lotto. In Deviate, Lotto explains that our brains don’t simply record the world as it is, but actively construct reality based on past experiences and evolutionary adaptations. Below, we’ll explain how our perceptual abilities don’t give us access to objective reality, as well as the evolutionary reasons why this is true. Then, we’ll outline how you can use this understanding of your brain’s abilities to change the way you think and foster innovation. Read more in our overview.
