This behavior reflects “delay discounting,” a mental filter used to make decisions about current versus future gains and losses, explained authors David Hardisty, M.Phil., and Elke Weber, Ph.D., of Columbia University.
No matter what the context, discounting stems from three factors: a bias for the present; uncertainty; and projected free time, money or other resources (such as new “green” technologies), said the authors.
“When we might gain, it’s simple: Those three factors make us want that gain right away. When we might lose, there’s a conflict,” Hardisty said. “We want to get the loss behind us, yet we also want to put it off – because we think it will be easier to pay later or the problem will somehow go away.”
Hardisty and Weber found that the resulting, seemingly counterproductive tendency to accept smaller gains now over bigger gains later applies not only to finance, but also to environmental planning.
Choosing the Short Term
The researchers conducted three studies with 65, 118 and 146 participants, respectively. They presented participants with a series of situations, forcing them to choose between different outcomes involving air quality, mass transit, garbage pile-up from a workers’ strike, and monetary gain and loss (for example, paying a parking ticket in a smaller amount now or a larger amount later).
As examples of the various scenarios presented, participants picked:
- 21 days of clean air now over 35 days of clean air next year;
- A short-term fix for mass transit now, instead of a long-term fix later; and
- A $250 lottery win now over a $410 win a year later.
Previous studies found that people are not always rational about personal finance. For example, if they came into some cash while carrying two loans, they might completely pay off the smaller loan right away, even though they could instead start paying off the larger, higher-interest loan – a strategy that would reduce their overall interest.
In the new studies, across scenarios, participants downplayed future gains significantly more than future losses. Therefore, researchers considered that framing environmental decisions as ways to avoid future loss rather than realize future gains may have an impact, said Hardisty.
For example, homeowners could be told that better insulation will help them avoid losing money to high utility bills, not that it will help them save – a subtle but influential semantic change. Similarly, campaigns to encourage people to buy higher-cost fluorescent light bulbs could highlight how their use will reduce future energy costs.
The study results were published in the American Psychological Association’s Journal of Experimental Psychology: General.
