As millions of people turn to social media for health information, better understanding the factors that guide health-related judgments and perceptions in this context is imperative. We report on two Web experiments (n>400 total) examining the power of society's widespread weight bias and related stereotypes to influence nutrition judgments in social media spaces. In Experiment 1, meals were judged as lower in nutritional quality when the person who recommended them (the source) was depicted as obese rather than of normal weight, an effect mediated by stereotypic beliefs about the source as a generally unhealthy person. Experiment 2 replicated this effect, which--notably--remained significant when controlling for objective nutritional information (calories and fat content). Results highlight spillover effects of weight bias that extend beyond person perception to color impressions of objects (here, food) that are associated with stigmatized attributes. Implications for everyday nutrition judgments and public health are considered.
随着数百万人转向社交媒体获取健康信息，在这种背景下更好地理解指导与健康相关的判断和认知的因素势在必行。我们报告了两项网络实验（总共n>400），研究社会普遍存在的体重偏见和相关刻板印象在社交媒体空间中影响营养判断的力量。在实验1中，当推荐餐食的人（来源）被描绘为肥胖而非正常体重时，餐食的营养质量被判定较低，这种效应由对该来源作为一般不健康的人的刻板信念介导。实验2重复了这一效应，值得注意的是，在控制客观营养信息（卡路里和脂肪含量）时，这一效应仍然显著。结果突出了体重偏见的溢出效应，这种效应超出了对人的认知，延伸到与被污名化属性相关的物体（这里指食物）的颜色印象。我们还考虑了对日常营养判断和公共卫生的影响。
