Hallgeir Sjåstad and Roy F. Baumeister, “The Future and the Will: Planning Requires Self-control, and Ego Depletion Leads to Planning Aversion.”
Journal of Experimental Social Psychology 76: 127-141, 2018.
• The authors hypothesize that the willingness to engage in the task of making plans for the future requires self-control; therefore, people who generally have low self-control ("trait" self-control) are less likely to plan, and people who are "ego depleted," who are fatigued ("state" self-control), also will be less likely to plan. (As with many notions in the behavioral sciences, ego depletion is not without its share of controversy.)
• This article, therefore, adopts the view that willpower draws on a depletable resource, and that when people have depleted that resource through cognitively taxing tasks, they will, in the short term, display reduced willpower (be ego-depleted). In other words, people with higher trait and state self-control will plan more.
• The authors conduct four studies. Study 1 looks at the correlation between trait self-control and planning; Study 2 and Study 3 ask if depletion (low state self-control) reduces planning; and, Study 4 tries to identify the channel through which ego depletion might undermine planning.
• Study 1 (N=201, Amazon Mechanical Turk, 30 cent payment per participant!) asks individuals questions about the extent of their self-control, their engagement in planning in the past, and their intended planning in the future. Sure enough, high self-control is associated with high past and future planning. Further, there is some evidence that women plan more than men.
• Study 2 is a lab experiment (n=105), where the control (non-depleted) group starts with a relatively easy, 12-minute writing task (avoid the letters x and z) and the depleted group has a 24-minute, difficult task (avoid the letters A and N); this depletion method is used to overcome problems identified in earlier experiments where shorter or less onerous tasks do not do much to distinguish the two groups. Those with the hard writing task report being both more exhausted and less interested (than those with the easy task) in making plans for the next four weeks. The depleted folks are less happy, too, but it doesn’t seem to be mood differences that dissuade the planning.
• Study 3 takes advantage of the possibility that shopping at Ikea tends to makes couples miserable! The participants (N=112) are Ikea shoppers in Norway, with half surveyed pre-shopping, and half surveyed post-shopping. Those who have completed their shopping report making many more recent decisions than the pre-shoppers, as well as being more exhausted. Further, post-shoppers are less willing to plan, though they do not express lower ambitions for the future. (They still want the benefits of planning, it seems, but are less willing to put in the effort.)
• Study 4 (N=128) picks up on the mechanism connecting ego depletion with planning aversion. Once again, laboratory participants are separated into depletion groups through differentially trying writing tasks. But in this experiment, they are given the opportunity to actually engage in planning, instead of just being asked about their intentions to plan in the future.
• The participants are asked how hard they like to work, and how hard they think planning would be. Again, the depleted folks avoid planning; further, they express a lessened desire to exert effort to engage in planning, and this altered desire (greater effort avoidance) mediates much of the relationship between depletion and planning: effort avoidance seems to be a major channel connecting depletion to reduced planning.
• "A vicious circle might develop in which failure to plan creates stresses and difficulties, which impose a further drain on limited self-regulatory resources, which in turn makes people all the more reluctant to plan [p. 139]."
