How can assumptions be challenged?

Tim Ferriss has discussed various methods to challenge assumptions:

1. Assumption Surfacing and Inversion:

   • Justin Gary introduced a practice where one surfaces all their assumptions individually or as a team and writes them down. They then systematically challenge each assumption by asking, "What if that weren't true?" or "What if I did the opposite?" This method proved powerful in uncovering core assumptions that could change everything when reevaluated. For example, Gary applied this technique for the game Soul Forge, initially a digital-only game, which led them to reconsider and subsequently launch a physical version too 1.

2. Provocative Thinking:

   • Scott Belsky emphasized the importance of provocative thinking. This involves assuming that one's beliefs may be wrong and then rigorously exploring the implications of that. By questioning doubts about key assumptions and investigating further, one can uncover significant insights. Belsky used this practice to re-evaluate leadership decisions and found it beneficial 2.

3. Core Belief and Value Examination:

   • Bryan Johnson highlighted the need to dig deeper into the beliefs and values driving decisions, often operating subconsciously. By identifying and challenging these deeply embedded assumptions, one can reveal the powerful yet invisible influences on decision-making. At Braintree, this approach was cultivated as an essential practice among his team 3.
