The effort heuristic is a mental rule of thumb in which the quality or worth of an object is determined from the perceived amount of effort that went into producing that object. In brief, the effort heuristic follows a tendency to judge objects that took a longer time to produce to be of higher value. The more effort invested in an object, the better it is deemed to be. This is especially true in situations where value is difficult to assess or the evaluator lacks expertise in the appraisement of an item. People use whatever information is available to them and effort is thought to generally be a reliable indicator of quality. An example of this would be the comparison of $100 earned, and $100 found. If someone finds $100 they are more inclined to go spend it on a whim, but if that $100 is part of a hard-earned paycheck, they are less likely to squander it away. Another way that effort heuristic can be considered is the amount of effort a person will put into an action depending on the goal. If the goal is of little importance, the amount of effort a person is willing to put into it is going to be lower.
== The Kruger study == There is experimental evidence that supports the notion that people sometimes use the effort that has been put into doing something as an estimate for its quality. The seminal study that investigated this phenomenon was done by Kruger, Wirtz, Van Boven, and Altermatt (2004). They conducted three experiments in which participants made judgments of quality—a poem in Experiment 1, paintings in Experiment 2, and medieval arms and armor in Experiment 3. In each experiment, they manipulated the effort seemingly invested in the objects' creation. Despite the fact that the actual quality of the work remained the same, they anticipated that manipulations in supposed effort would influence perceived quality.
=== Experiment 1 === In the first experiment, participants evaluated a poem with respect to how much they enjoyed it, the overall quality of the poem, and the amount of money a poetry magazine would pay for the poem. They were told that the experiment concerned the way in which people evaluate poetry. The subjects were randomly assigned to one of two condition groups in this study: low effort and high effort. Participants in the low effort condition were told that the writer spent 4 hours on the poem while participants in the high effort condition were told the poet spent 18 hours on the piece. The researchers combined the liking and quality measures into one composite result and found participants provided more favorable evaluations of the poem when they thought it took the poet 18 hours to compose rather than when they thought it took him 4 hours. They also judged the more effortful poem to be worth more money.
=== Experiment 2 === In the second experiment, non-experts and self-identified experts individually evaluated the quality of two paintings by Deborah Kleven: 12 Lines and Big Abstract. Half of the participants were told that the former took 4 hours to paint and the latter 26 hours, and the other half were told the opposite. After rating each painting separately, participants then compared the two paintings directly. The results revealed that participants preferred 12 Lines over Big Abstract when they thought 12 Lines took longer to paint, but the opposite tended to be true when they thought that Big Abstract took longer to paint. The effort manipulation had a similar effect on participants estimates of how much the paintings were worth. Participants who thought 12 Lines took longer to produce thought that it was worth more money than Big Abstract, whereas the opposite tended to be true when participants thought that Big Abstract took longer to paint. The data also indicated that the effect of perceived effort on perceived quality was independent of whether participants had self-professed expertise in the domain. Self-identified art experts did not appear to rely on effort any less than novices, despite the fact that the self-identified experts were presumably more practiced at evaluating art. This points to the generality and intuitive appeal of effort as a heuristic for quality.
=== Experiment 3 === In the third and final experiment, researchers asked participants to rate the quality of several images of medieval arms and armor presented on a computer screen. When rating the final target piece of armor, half of the participants were told that it took the blacksmith 110 hours to complete, and half were told that it took 15 hours. In addition to manipulating the perceived effort invested by the artist, researchers also varied the ambiguity of the stimulus to examine its potential as a moderator in the use of the effort heuristic. This was done by altering the resolution of the image where half of the participants viewed a high-resolution image of the piece, and half viewed a low-resolution image. Experiment 3 produced similar results as the first two; participants provided higher ratings of the piece when they thought it took the blacksmith longer to produce. The more effort invested in the object, the better it was assumed to be. The influence of effort on judgment was also bigger in the high-ambiguity condition than in the low-ambiguity condition. This was expected because the quality of the armor was more ambiguous in the low-resolution condition. Participants in this condition had less objective information upon which to make a judgment of quality, and thus were more likely to rely on the perceived effort invested by the blacksmith while evaluating.
