Meat consumption has a host of serious negative consequences for nonhuman animals, underprivileged humans, and the natural environment. Several interventions have been developed to encourage meat reduction but to relatively limited effect. There is also a range of established predictors of meat consumption, but much less is known about the factors that predict intentions to reduce meat consumption. The goal of this study was to determine the roles of personality and self-knowledge in meat reduction intentions.
In this set of three preregistered studies, we tested brief interventions to encourage meat reduction intentions and examined personality predictors of intentions to reduce meat consumption.
We found no evidence that brief interventions with or without a self-knowledge component had a meaningful effect on changing meat reduction intentions. However, we found robust evidence for relatively small associations between intending to eat less meat and high Openness to Experience, high Emotionality, and perceiving meat reduction as moral behaviors.
Individual differences may be a more influential predictor of meat reduction intentions than brief interventions. Implications for promoting meat reduction are discussed.
肉类消费对非人类动物、弱势群体和自然环境都有一系列严重的负面影响。已经开发出了几种干预措施来鼓励减少肉类消费，但效果相对有限。还有一系列已确立的肉类消费预测因素，但人们对预测减少肉类消费意图的因素知之甚少。本研究的目的是确定个性和自我认知在减少肉类消费意图中的作用。
在这一系列三项预先注册的研究中，我们测试了鼓励减少肉类消费意图的简短干预措施，并研究了个性预测因素与减少肉类消费意图之间的关系。
我们没有发现带有或不带有自我认知成分的简短干预措施对改变减少肉类消费意图有明显影响的证据。然而，我们发现，打算少吃肉与高开放性、高情绪性以及将减少肉类消费视为道德行为之间存在相对较小的关联，这一证据非常可靠。
与简短干预相比，个体差异可能是减少肉类消费意图的更具影响力的预测因素。讨论了促进减少肉类消费的意义。
