Though survey satisficing, grudging cognitive efforts required to provide optimal answers in the survey response process, poses a serious threat to the validity of online experiments, a detailed explanation of the mechanism has yet to be established. Focusing on attitudes toward immigrants, we examined the mechanism by which survey satisficing distorts treatment effect estimates in online experiments. We hypothesized that satisficers would display more stereotypical responses than non-satisficers would when presented with stereotype-disconfirming information about an immigrant. Results of two experiments largely supported our hypotheses. Satisficers, whom we identified through an instructional manipulation check (IMC), processed information about immigrants’ personality traits congruently with the stereotype activated by information provided about nationality. The significantly shorter vignette reading time of satisficers corroborates their time-efficient impression formation based on stereotyping. However, the shallow information processing of satisficers can be rectified by alerting them to their inattentiveness through use of a repeated IMC.

オンライン調査に回答する際に協力者が応分の注意資源を割こうとしない行動(努力の最小限化;Satisfice)が心理学の研究結果に及ぼす影響について検討しました。調査冒頭で努力の最小限化をした協力者は、事後の人物イメージ評価において、その人が他国民の場合は、その人の性格に関する情報よりも、その人の国籍に応じたステレオタイプにひきずられた回答をする傾向がありました。しかし、こうした傾向は、努力の最小限化に警告を与え、回答者の行動を修正することである程度解消されることがわかりました。
