10. General discussion
Across three studies, we find that making a backup plan can indeed have harmful effects on goal pursuit (Studies 1–3). In Study 1, we find that making a backup plan leads to reduced primary goal performance. In Study 2a and 2b, we replicate the main effect from Study 1, while ruling out alternative explanations for this effect. Results from Study 2a rule out the possibility that our backup plan manipulation reduces primary goal performance by dampening the appeal of the superordinate goal, and results from Study 2b show that mere fatigue from brainstorming cannot explain our main effect. In Study 3, we find evidence that the mediating mechanism driving the backup plan effect is a dampening of the desire for goal success, and we further rule out distraction as an alternative mediating mechanism.
