Does the way individuals think about the burdens and benefits of giving time to charity depend on how that time is distributed? Prior work shows that the assessment of a whole is different than the assessment of the sum of its parts. Drawing on this work, we demonstrate that when a volunteer experience is segregated into multiple parts (vs. aggregated into a whole)—for example, volunteering 4 h a day for 2 days versus 8 h in a single day—individuals expect the process to feel less effortful but also the outcome to feel less morally right. In addition, we find that contribution size has a moderating effect on anticipated effort (but not on anticipated morality). Lastly, we find that individuals who focus on minimizing the effort involved in volunteering (vs. maximizing the impact of volunteering) show a greater likelihood of volunteering in a segregated (vs. aggregated) manner. We discuss theoretical and practical implications of these findings.

隔离与聚合志愿服务的预期努力和道德

个人对为慈善事业付出时间的负担和收益的看法是否取决于时间的分配方式？先前的工作表明，对整体的评估不同于对其部分总和的评估。借鉴这项工作，我们证明了当志愿者经历被分成多个部分（与聚合成一个整体）时——例如，每天志愿服务 4 小时，持续 2 天，而在一天中志愿服务 8 小时——个人期望这个过程能够感受到不那么努力，但也会导致在道德上感觉不那么正确。此外，我们发现贡献大小对预期努力（但对预期道德）有调节作用。最后，我们发现那些专注于尽量减少志愿服务工作的人（与 最大限度地提高志愿服务的影响）表明以隔离（与聚合）方式进行志愿服务的可能性更大。我们讨论了这些发现的理论和实践意义。
