Mental Models
A mental models app should give you a toolkit of thinking frames and the judgment to reach for the right one — first principles when assumptions need questioning, inversion when failure needs avoiding, systems thinking when a problem keeps recurring. ZenWitGo trains that through short daily missions built around the models generalists actually use.
First-principles missions break a problem down to what must be true and rebuild from there, questioning the industry assumptions and cost structures everyone else takes as given. Inversion missions run the pre-mortem: instead of chasing success, you list the ways a plan fails and design those out first.
Circle-of-competence missions train an honest read of where your knowledge ends, so advice-seeking and risk-taking match what you actually know. Occam’s and Hanlon’s razors sharpen how you explain events — favouring the simplest account and reading incompetence before malice. Margin-of-safety missions build in buffers for money, schedules, and engineering, while systems-thinking missions surface feedback loops, bottlenecks, and the leverage points where a small push moves the whole system.
XP and a daily streak keep the practice steady, so these frames become instincts you apply to a new problem rather than names you can only recite.

Questions
- What is a mental models app?
- A mental models app trains reusable thinking frameworks — first principles, inversion, second-order effects, margin of safety, systems thinking — through short scenarios, so you can match the right model to a real problem.
- What are first principles?
- First-principles thinking strips a problem to the facts that must be true and reasons up from there, instead of copying how things are usually done. Missions drill it on business, cost, and design problems.
- How is this different from memorising a list of models?
- A list tells you the names; ZenWitGo drills selection and use. Practising each model on varied concrete cases is what makes you reach for the right one when a fresh problem arrives.
- Which models does ZenWitGo cover?
- Missions span first-principles thinking, inversion, second-order effects, circle of competence, Occam’s razor, Hanlon’s razor, margin of safety, and systems thinking.
