By communicating our own uncertainty when sharing beliefs with others, we are inviting the people in our lives to act like scientists with us. This advances our beliefs at a faster clip because we miss out on fewer opportunities to get new information, information that would help us to calibrate the beliefs we have. Acknowledging that decisions are

We would be better served as communicators and decision-makers if we thought less about whether we are confident in our beliefs and more about how confident we are. Instead of thinking of confidence as all-or-nothing (“I’m confident” or “I’m not confident”), our expression of our confidence would then capture all the shades of grey in between.

But that doesn’t mean we can’t change the framework for ourselves in the way we think about our decisions. We can train ourselves to view the world through the lens of “Wanna bet?” Once we start doing that, we are more likely to recognize that there is always a degree of uncertainty, that we are generally less sure than we thought we were, that

The stubbornness of beliefs Flaws in forming and updating beliefs have the potential to snowball. Once a belief is lodged, it becomes difficult to dislodge. It takes on a life of its own, leading us to notice and seek out evidence confirming our belief, rarely challenge the validity of confirming evidence, and ignore or work hard to actively

Truthseeking, the desire to know the truth regardless of whether the truth aligns with the beliefs we currently hold, is not naturally supported by the way we process information. We might think of ourselves as open-minded and capable of updating our beliefs based on new information, but the research conclusively shows otherwise. Instead of

We form beliefs in a haphazard way, believing all sorts of things based just on what we hear out in the world but haven’t researched for ourselves. This is how we think we form abstract beliefs: We hear something; We think about it and vet it, determining whether it is true or false; only after that We form our belief. It turns out, though, that we

This is ultimately very good news: part of the skill in life comes from learning to be a better belief calibrator, using experience and information to more objectively update our beliefs to more accurately represent the world. The more accurate our beliefs, the better the foundation of the bets we make. There

In most of our decisions, we are not betting against another person. Rather, we are betting against all the future versions of ourselves that we are not choosing. We are constantly deciding among alternative futures: one where we go to the movies, one where we go bowling, one where we stay home. Or futures where we take a job in Des Moines, stay at

The betting elements of decisions—choice, probability, risk, etc.—are more obvious in some situations than others. Investments are clearly bets. A decision about a stock (buy, don’t buy, sell, hold, not to mention esoteric investment options) involves a choice about the best use of financial resources.
