A nominally significant interaction effect of +0.378 in the audit is not actually identified as preference, with 79-85% of it reproducible from severity shift and scale floor alone without any differential preference

The audit's one nominally significant interaction, $+0.378$ ($p = 0.002$), is not identified as preference: a construction containing zero differential preference reproduces 79 to 85\% of it from the observed severity shift and the scale floor alone
