- When building your illness scripts, pay attention to clinical findings that are characteristic for the diagnosis, rather than merely consistent with the diagnosis.
- Characteristic findings are hallmarks of a particular diagnosis. They are usually present, and when they are, they strongly support the diagnosis; when they are absent, they argue strongly against the diagnosis. I.e. their presence or absence significantly alters the likelihood of a diagnosis.
- Expert diagnosticians rapidly recognize characteristic findings, based on the clinical context.
- Hypothesis driven reasoning often involve both the fast and slow processor. Optimal utilization of the combination is crucial to avoid cognitive biases
- An anomalous clinical data is often times the only clue to the incoherence of a hypothesis. Its presence calls for rethinking your diagnosis creatively, don’t ignore it!
- Disease processes that involve multiple organ systems may have highly variable clinical presentation. Don’t be fooled by a rigid illness script.
