How do I practice indirect evidence?

The most direct way to practice indirect evidence is through a focused exercise: Identify one schema you hold that cannot be tested through a single direct observation — something about your motivation, your relationships, your learning style, or your decision-making tendencies. Write the schema as a clear statement. Then generate five independent indicators that would be present if the schema were true and five that would be present if the schema were false. For each indicator, note what kind of evidence it represents (behavioral pattern, emotional response, outcome distribution, testimony from others, or written record). Finally, assess: how many of the "true" indicators can you currently observe? How many of the "false" indicators? Write a one-paragraph verdict on the schema based on the convergence pattern, noting explicitly which signals agree and which conflict.

Common pitfall: Treating the absence of direct evidence as the absence of any evidence. This is the error of demanding courtroom-standard proof for every schema, then concluding that schemas about internal states, relationships, or complex systems are simply unknowable. The opposite failure is equally dangerous: accepting a single indirect indicator as definitive proof because it confirms what you already believe. Both errors stem from the same misunderstanding — not recognizing that indirect evidence works through convergence, not through any individual signal.

This practice connects to Phase 15 (Schema Validation) — building it as a repeatable habit compounds over time.
