Critical Rationalism applied to the question of how to live well.


Misconcepts is a framework for life built on Critical Rationalism, our best theory of what knowledge is and how it grows. We coined the term misconcepts to describe the mental models we hold of the world, as a reminder that no model is ever perfect and thus can always be improved.

Misconcepts are your life.

Your internal experience originates from misconcepts.

A brain sitting inside a dark skull, receiving nerve impulses from the external world and generating internal experience

Your external results originate from misconcepts.

A brain making decisions that lead to actions and compounded results in the external world

The only two things you ever do are improve or implement your misconcepts.

Improve misconcepts or implement them — the two activities

Quality misconcepts matter.

High quality misconcepts: expectations align with reality, equanimity follows inevitably Low quality misconcepts: expectations not aligned with reality, frustration follows

Higher quality misconcepts generate expectations that reflect reality more closely, resulting in internal calm and equanimity.

Lower quality misconcepts contain more errors and generate expectations that diverge from reality, resulting in frustration and suffering.

High quality misconcepts: decisions and actions produce predicted outcomes, compounding accelerates Low quality misconcepts: decisions and actions do not produce predicted outcomes, compounding haphazard

Higher quality misconcepts produce decisions and actions that compound toward your intended results.

Lower quality misconcepts compound too, but slowly, haphazardly, or in the wrong direction entirely.

Error correction matters.

Misconcepts are models of the world.

Quality misconcepts contain less errors and approximate reality closer.

Progress comes from acquiring misconcepts with less errors.

Prioritisation matters.

Time, physical resource, and mental resource are finite.

Error correcting one misconcept comes at the cost of another.

So which misconcept has the highest ROI?

High level misconcepts are invoked in every single decision and action you take.

Making them fit-for-purpose first is your highest ROI investment.

Highest ROI Misconcepts.

Misconcepts

Fallible mental models of the world. They contain mistakes and can be improved through conjecture and criticism. The closer they reflect reality, the better your internal experience and external results.

Arbitrary Life Goals

A conjectured desired state that you choose to pursue. Arbitrary because there is no externally prescribed meaning or purpose that dictates what your goals should be. You can freely conjecture, criticise, and iterate on your life goals.

Life Resources

Finite life resources you use to improve your misconcepts, or to implement them. Includes primary life resources (time, mental resource, physical resource) and secondary life resources (financial resource, misconcepts set, social capital).

Opportunity Cost

The lifetime value of the next best alternative foregone when expending life resources. Since life resources are finite, opportunity cost is present in every decision you make, whether acknowledged or not.

    The invisible cage you built yourself

    Most people never ask who wrote the rules they live by. They just get very good at following them.

    Frugality is not the point

    Frugality was never the goal. It was always a means to one.
