# What does 'customer loyalty' look like when AI makes the choice?

**Open question:** Customer loyalty has traditionally rested on **emotional connection, brand affinity, and habit.** If an agent is told, *"Reorder my usual groceries and make substitution decisions if the total is under $200,"* it may swap a "loyal" brand for a cheaper alternative on pure algorithmic logic. How do brands build or maintain loyalty when the decision-maker lacks emotion?

**Why it matters:** It directly conditions the gatekeeper threat in [[claim-ai-as-gatekeeper]] and the persuasion gap in [[concept-bnn-vs-ann]].

**Resolution path:** Research how to **prompt-engineer user preferences** or build **trust signals that ANNs heavily weight during substitution decisions**. *(Enrichment counterpoint: if agents optimize for human satisfaction, brand affinity encoded in user preferences and strong reviews may still exert pull — loyalty may migrate from the emotional layer to the preference-specification and trust-signal layer.)*
