MWITA-LRO-2026-009 · Evidence A · P1
Randomly soliciting a hotel review reduced the solicited customer's subsequent brand spending by $16, or 7%, on average; harm was concentrated among less-than-perfectly-satisfied, highly loyal customers.
What this does not establish
The posting LATE applies to solicitation compliers under exclusion and monotonicity assumptions; it is not the effect of public ratings on other customers, aggregate demand, or all review-request channels.
Counterevidence & uncertainty
Solicitation successfully increases review creation yet can decrease the reviewer's own future spend; perfectly satisfied customers show no spending penalty, rejecting a uniform backfire claim.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
