Drawing upon the hostile media effect, this study examined how perceived media bias in covering genetically modified (GM) food influences individuals' risk-benefit assessments of it and their food consumption behaviors. The results of a nationally representative survey (N = 1364) showed that individuals seeing media coverage as more biased in favor of GM food perceived it as more hazardous, which was related to a higher proportion of organic food consumption in their diets. In contrast, perceived media coverage as less slanted toward GM food was associated with more benefit perceptions of it, thereby predicting its higher proportion in individuals' diets. More importantly, the indirect effect of perceived media bias on GM food consumption through benefit perceptions was more pronounced among males than females. The findings of this study not only provide empirical evidence of the perceptual and behavioral outcomes of hostile media perceptions, but also offer valuable insights for journalists and education practitioners to improve public understanding of emerging food technologies.
本研究借鉴了敌意媒体效应，探讨了个体对媒体在报道转基因食品时的偏见感知如何影响他们对该食品的风险-收益评估以及他们的食物消费行为。一项全国代表性调查（N=1364）的结果表明，认为媒体报道更偏向转基因食品的个体认为该食品更危险，这与他们饮食中更多的有机食品消费有关。相比之下，认为媒体报道对转基因食品的偏见较小与更高的收益感知相关，从而预测了该食品在个体饮食中的更高比例。更重要的是，通过收益感知，感知媒体偏见对转基因食品消费的间接影响在男性中比女性更为明显。本研究的发现不仅为敌意媒体感知的感知和行为结果提供了经验证据，也为记者和教育从业者提供了有价值的见解，以提高公众对新兴食品技术的理解。
