The second experiment measured the impact of trust in 107 participants. After viewing the video clip, they were asked to rate how much they trusted the person providing advice regarding the weight estimate. Those who experienced incidental gratitude were more trusting and receptive to advice than were those in the neutral state, and those who experienced incidental anger were less trusting and receptive than participants in the neutral state.
In the conclusion, the authors expect that those who make us angry, or trigger anger to be “less trusted and less influential.” The authors expect that those “who are able to generate gratitude (e.g., by causing targets to reflect on their good fortune),” are able to create “more trust and to be more influential."
What does this mean to us? The theory of rational behavior might be just that, a theory that is not borne out in real life. As humans with emotions, incidentally or directly caused by the activity and the decision at hand, we might be influenced much more than we think by emotions.
This might be fine when gratitude for my child’s good manners allows for 5 minutes more playtime outside, but we might want to rethink the irrationality of rational theory.
