MWITA-NCO-2026-011 · Evidence B · P1
A 3D tablet-AR dessert menu more than doubled the share of diners ordering dessert versus a 2D tablet control; dimensionality and environmental superimposition were bundled and cannot be separated.
What this does not establish
Assignment alternated by table rather than concealed individual randomization, N was small, and observation covered two evenings in one undisclosed large international city; participants received a GBP 5 bill discount. The treatment bundled 3D rendering with environmental superimposition. Purchase incidence is not dessert revenue, margin, satisfaction, refund, repeat visit or churn.
Counterevidence & uncertainty
The result establishes a purchase difference in this setting but does not show whether AR raised total bill value or profitable demand; the study bundled dimensionality with superimposition.
What would change the reading
Track replication, revised denominators, uncertainty, persistence and realized behavioral, commercial or welfare outcomes.
