Why we cite it
A clean, Wansink-independent demonstration of the health halo effect with two elegant experiments. Study 1 showed that simply labeling Oreos as “organic” led participants to judge them lower in calories on a 7-point scale (b = 1.22, p < .001), even though both labels stated 160 calories. (Corrected 2026-09-10 from "caused 38% of participants to judge them as lower calorie (vs. 12% for conventional)": the paper contains no percentages.) Participants also said organic cookies could be eaten more often. In Study 2 participants were "significantly more lenient toward Susie forgoing exercise when she had chosen an organic dessert" rather than a conventional one. That is a judgement about a described person, and nobody ate a dessert. Perceived goal progress is the authors' framing of the prediction ("To the extent that the act of eating organics is construed as progress toward a weight-loss goal"), not a finding. (Corrected 2026-09-10 from "people judged it more acceptable to skip exercise after eating organic (vs. conventional) dessert, suggesting the organic label creates an illusion of goal progress".) The pro-environmental moderation is particularly relevant for the project's audience. This paper is the preferred primary source for health halo claims because it is independent of the Wansink research fraud controversy — Schuldt trained under Schwarz at Michigan, not at Cornell's Food and Brand Lab.
