Personalization and chance
Organizers can arrange familiar material, deliberately unfamiliar activity, random selections, unplanned periods in the same shared setting. They identify the purpose of a particular curatorial choice and examine the participant's response.
A related book may help someone continue an earlier question. An unrelated conversation in the kitchen may introduce another practice. Repeatedly selecting only predicted interests can reduce later opportunity for unfamiliar encounters. The institution can preserve other reasons for placement, time for independent activity, occasions with no individual targeting.
Algorithmic convergence examines the narrowing process. Curatorial proposals and physical attention describe different routes to unfamiliarity. Researchers can compare discovery, remembered material, participant judgment, subsequent activity without assuming one universal amount of surprise suits every occasion.
