 Unlike the "fox and the grapes" approach, which explains how underperception occurs in men as a means of face-saving, reciprocity reflects a real shift in the level of interest in a partner as a result of returning the perceived interest.Similar examples can also be seen in the judgment of whether a noise in the wild was a predator when it was more likely the wind—humans who assumed it was a predator were less likely to be attacked as prey over time than those who were skeptical.This is similar to the animistic fallacy.
