MDPE.20:3.5 - Derive observations that distinguish the trajectories

Ask what would differ if the practice developed along one trajectory rather than another. Useful observations can include reproduction errors across iterated teaching or imitation chains; return, interference, or transfer under changed cues, partners, music, venues, or transition orders; performer success and burden across bodies, instruments, tempi, phrase structures, and configurations; recognition by partners, teachers, audiences, judges, or sensors; continued enactment across events and periods; distribution changes across populations; responses to changed network, recommendation, judging, teaching, or access arrangements; and persistence, reversal, splitting, or disappearance after a pressure is removed.

First decide whether a further observation is needed for the receiving judgement, worth its full design, acquisition and participant burden, and obtainable with actual capability, consent, access, resources and a useful window. If selected, specify:

• which rival trajectories predict different outcomes;
• the capable Agent, bounded observation Work, and direct Music, Dance, teaching, experiment-design, active-learning, event, platform, cultural-evolution, or engineering Method that the Work will enact;
• the population, setting, comparison, representation, and time window;
• the sampling, measurement, transfer, consent, and burden limits;
• what result would retain, narrow, reject, replace, or add a trajectory; and
• what decision may change.

Prefer a selected observation that can discriminate among mechanisms over one that merely adds compatible evidence. Ground relied-on observations through A.10; state characteristics and temporal limits through C.16 and C.27. An inconclusive observation is a complete empirical result with its limits. A qualified current forecast or preparation/stop decision can also be complete without commissioning an observation.
