People sometimes choose to remain ignorant, even when information comes at low marginal costs and promises high utility. To investigate whether older adults enlist deliberate ignorance more than younger adults, potentially as an emotion-regulation tool, we presented a representative sample of 1,910 residents of Germany with 13 scenarios in which knowledge could result in substantial gains or losses. The strongest correlate of deliberate ignorance was indeed age. Openness to experience was negatively correlated with deliberate ignorance; risk preference did not and neuroticism did not consistently predict it. Findings suggest a possible positivity effect in the decision to access new but ambiguous information. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

故意无知的年龄差异。

人们有时选择保持无知，即使信息以低边际成本提供并承诺高效用。为了调查老年人是否比年轻人更倾向于故意无知，这可能是一种情绪调节工具，我们提供了一个由 1,910 名德国居民组成的代表性样本，其中包含 13 种知识可能导致重大收益或损失的情景。与故意无知最密切相关的确实是年龄。对经验的开放性与故意无知呈负相关；风险偏好没有，神经质也没有一致地预测它。调查结果表明，在决定访问新的但模棱两可的信息时可能存在积极影响。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
