“Specially For You” – Examining the Barnum Effect’s Influence on the Perceived Quality of System Recommendations

Research-assisted source review

What it supports
Personalised labelling produced no significant quality increase and numerically lower mean ratings overall; actual movie-set quality strongly affected ratings.
Where it may not transfer
Movie recommendations and a short online experiment are not personality assessment. The study estimates the labelling effect in one interface and does not rule out small or subgroup-specific effects.
