In This Episode We Discuss

What is science meant to be? What is science pragmatically?
"Science doesn't prove anything it just reduces uncertainty"
If you want to know something better, it takes concentrated cognitive effort and thinking. Wrestle with difficult ideas. Don't just consume
What information do you have that you can collect, how does that inform your mental model? And how do you test that model
Crucially, how do you disprove that model?
Application: explicit vs. tacit knowledge. (Tacit = coach intuition)
Adding that knowledge to a larger body of evidence
You don't identified as your views, but as the being that has certain views that are subject to change
Far important how you think than what you think
