How do I practice temporal reasoning?

The most direct way to practice temporal reasoning is through a focused exercise: Find a belief you hold now that contradicts something you believed three or more years ago. Write both versions down with dates: 'In [year], I believed [X]' and 'Now, in 2026, I believe [Y].' Then answer three questions: (1) What changed in the environment between then and now? (2) What changed in you? (3) Is the old belief still true in some contexts, or is it fully obsolete? You are practicing temporal disambiguation — separating claims by the time at which they were valid rather than forcing a single timeless truth.

Common pitfall: Assuming that because your current belief contradicts a past belief, one of them must have been wrong. This is presentism — judging past reasoning by present conditions. The subtler failure is the opposite: assuming your current beliefs are as time-bound as the ones they replaced, and therefore refusing to commit to anything. Time disambiguation does not mean every belief is temporary. It means you check whether the variable that changed is time, or something else entirely.

This practice connects to Phase 19 (Contradiction Resolution) — building it as a repeatable habit compounds over time.
