Three studies confirm the existence of the return trip effect: The return trip often seems shorter than the initial trip, even though the distance traveled and the actual time spent traveling are identical. A pretest shows that people indeed experience a return trip effect regularly, and the effect was found on a bus trip (Study 1), a bicycle trip (Study 2), and when participants watched a video of someone else traveling (Study 3). The return trip effect also existed when another, equidistant route was taken on the return trip, showing that it is not familiarity with the route that causes this effect. Rather, it seems that a violation of expectations causes this effect.
返程往往看起来比初始行程短，即使行驶的距离和实际旅行时间相同。预测试表明，人们确实经常经历返程效应，而且这种效应在公共汽车旅行（研究 1）、自行车旅行（研究 2）以及当参与者观看他人旅行的视频时（研究 3）都存在。当在返程中选择另一条等距的路线时，返程效应仍然存在，这表明不是对路线的熟悉导致了这种效应。相反，似乎是违反预期导致了这种效应。
