Halo effect

Evaluating more than one factor in a sample may produce a halo effect. The
panelist often forms a general impression of a product and if asked to
evaluate it for odor, texture, color, and taste at the same time, the results
may differ from those when each factor is rated individually. In effect, the
rating of one factor influences the rating of another. For example, in meat
evaluations, often panelists will rate a dry sample tougher than it would be
if tenderness alone were being assessed. When resources allow, eliminate
this effect by evaluating only one characteristic at a time.
