What was the main finding of the study conducted by Steven cesie and Jeffrey Leica at Brandy Wine Raceway?

They found that the expert gamblers were able to unconsciously model their predictions of a horse's chance of winning as a complex linear equation with seven variables related to the horse's past performance.

What is the purpose of the online test created by the speaker, and how does it work?

The online test measures a person's risk intelligence quotient (RQ) by asking them to rate the likelihood of 50 statements as true or false, expressing their certainty or uncertainty as a percentage.

How does the speaker define 'overconfidence' and 'underconfidence' in the context of the risk intelligence test?

Overconfidence is when a person is too certain about their knowledge or predictions, while underconfidence is when they are not confident enough. The test aims to find a balance, where confidence matches the actual knowledge or situation.

What are the three ways the speaker suggests using probabilities when making decisions?

The three ways are setting a threshold for decision-making, bet sizing which involves betting proportional to confidence, and using the concept of expected value to make decisions over a longer time horizon.
