Incremental Progress
also Small steps · Learning many small skills · Gradualism
Advancing by many small, individually-checkable steps from your current baseline, instead of attempting large jumps that produce more errors than you can correct.
Incremental progress is CF’s prescription for how to learn and improve without getting stuck: identify your baseline (what you can already do successfully and check on your own with ease), then take one small step beyond it, repeat, and let later steps build on earlier ones. A “small” step is one you can complete with only a couple of errors; twenty errors means the step was too big.
The core argument is mechanistic. Trying to learn many new things at once compounds difficulty faster than linearly, because each unfamiliar element multiplies the kinds of mistakes you must diagnose simultaneously. By isolating roughly one new thing at a time, you keep your error rate low enough that your error-correction capacity can keep up. This makes incremental progress CF’s direct antidote to overreach — attempting work whose error rate outpaces your ability to correct errors, which leads to a growing backlog and failure.
CF stresses prioritizing success: aim for a success rate above 90% (75% can still work; near 50% is trouble), and on a failure streak drop the next step’s difficulty exponentially. Each step should be one you can self-evaluate; if you cannot judge your own success, you are working above your baseline. Because progress must accumulate, steps should be organized into sub-goals and made to build on each other rather than restart from scratch — many small wins compounding, supported by practice and self-generated activities, rather than one heroic leap. This shares the spirit of piecemeal reform in Popper’s epistemology: small, correctable changes over sweeping ones.
