She introduces the "10-10-10" framework or the concept of "betting" on one's beliefs. By asking, "How much would I bet on this being true?" an individual forces themselves to quantify uncertainty. For example, rather than stating "I know this project will succeed," a nuanced thinker states, "I am 70% confident this project will succeed based on current data." This shift accomplishes two goals. First, it protects the ego; if the project fails, the individual was "correct" about the 30% risk of failure. Second, it opens the door to new information. If one holds a belief at 100%, contradictory information feels like an attack. If one holds a belief at 70%, new information is simply data that adjusts the percentage to 65% or 75%. This flexibility is the essence of the "Growth Mindset."

Note: As with any PDF, ethical sourcing matters. Duke’s work is available through legitimate retailers like Amazon Kindle, Google Play Books, and directly from the publisher’s e-book store. Supporting authors ensures more books like this get written.

A bet, in Duke’s framework, is simply a decision made under uncertainty where you weigh probabilities, accept that you could be wrong, and put something of value on the line (reputation, money, time, happiness). When you think in bets, you stop asking “Am I right or wrong?” and start asking “What are the odds I’m right?”
