Naive Cynicism: Expecting Others to Be More Self-Serving Than They Are

Two things happened with the person you share a home with, one that went well and one that went wrong, and you were equally responsible for both. Four sliders ask how they would split the credit and the blame, and how you would; the page compares the two shares you expected them to claim and sets them beside the 1999 studies.

Four sliders show how self-serving you expect the other person to be

Picture the person you share a home with and two things from this month. The good one: a dinner the two of you hosted went well, and you each did about half the work. The bad one: a shared bill went unpaid and you were both charged a late fee, because each of you assumed the other had paid it. Take it as given that you were equally responsible for both. Two sliders ask how your housemate would split the credit and the blame if asked, two ask how you would. The page compares the two shares you expected them to claim with each other; the even-split line is drawn only for reference. Only the final label leaves the page. That label is counted anonymously.

At the end you see your own result next to the figure from Kruger and Gilovich, and how visitors so far compare.

In Kruger and Gilovich's four 1999 studies, married couples, video game partners, debaters and darts players divided responsibility for good and bad joint outcomes and predicted how the other person would divide it; in every study participants expected the other person's allocations, but not their own, to be self-servingly biased, whether or not those allocations actually were.

In short

Naive cynicism is the expectation that other people will judge in a self-serving way, claiming more than their share of good outcomes and less than their share of bad ones, while you yourself judge fairly, an expectation that outruns how self-serving those other people actually are. It shows up between partners dividing housework, between colleagues sharing credit for a project, between opposing teams, and in the assumption that anyone who disagrees with you is driven by interest rather than by judgment.

How naive cynicism works

Naive cynicism is a theory about other people's minds that happens to be wrong in a predictable direction. Most people know that judgments of responsibility can be self-serving, and they apply that knowledge to everyone but themselves: the other person, they assume, will take the credit and shed the blame. Kruger and Gilovich showed in 1999 that this assumption is held even when the other person's actual allocations are not self-serving, so the cynicism is naive in the sense that it is applied by default, without checking.

A second finding sits beside it. Ross and Sicoly had shown in 1979 that both partners in a couple tend to claim more than their share of joint activities, pleasant and unpleasant alike, so that the two claims add up to more than the whole. That is an egocentric bias: your own contributions are easier to recall, so your share looks larger whatever the activity. What Kruger and Gilovich's participants expected from their partners was something else, a motivated pattern of grabbing credit and dodging blame, and they expected it whether or not the partner's actual allocations were self-serving. The two patterns are easy to confuse because both end in someone claiming too much, but they come apart on the bad outcomes: an egocentric allocator claims a large share of the blame as well, a self-serving one does not.

The expectation is sensitive to motive, which is a clue to where it comes from. In the debating and darts studies, participants assumed their teammates would be less biased than their opponents. People seem to reason from what they think the other person wants: an opponent wants to win, so an opponent will judge in their own favor. The reasoning is not foolish. It is just applied as if wanting a result were enough to distort a judgment, and applied without checking: the expectation held whether or not the other person's actual allocations were biased, which is what makes the cynicism naive.

Naive cynicism belongs to a wider family of findings about the overestimation of self-interest. Miller and Ratner showed in 1998 that people overestimate how much financial reward and group membership drive their peers' attitudes and behavior, and Miller argued in 1999 that a cultural norm of self-interest leads people to expect it in others, and sometimes to perform it themselves so as not to look naive. Cynicism about others is in that sense learned, and it is learned in excess of the facts.

The original study

Justin Kruger and Thomas Gilovich published "'Naive cynicism' in everyday theories of responsibility assessment: On biased assumptions of bias" in the Journal of Personality and Social Psychology in 1999. The paper reports four studies with the same core design. Participants divided responsibility for a series of joint outcomes, some desirable and some undesirable, between themselves and another person, and then estimated how that other person would divide the same responsibility.

The four samples were chosen to vary the relationship. Study 1 used married couples, who allocated responsibility for events in their marriage. Study 2 used video game enthusiasts. Study 3 used debaters and Study 4 darts players, settings in which the other person could be a teammate or an opponent. In every study the finding was the same: participants expected the other person's allocations, but not their own, to be motivationally biased, with the other person taking more credit for the good outcomes and less responsibility for the bad ones. The expectation held regardless of whether the other person's actual allocations were biased in that way.

Different behavior, the same cynical expectationTwo illustrative scenes show the same partners: a filled silhouette observing a partner with swept hair and a diamond on their shirt. In one observed scene they jointly hold a trophy for credit and a crossed token for blame; in the other, the partner pulls the trophy toward themselves and pushes blame away. Above each scene, a thought bubble linked to the observer contains the identical image of the partner taking credit and shedding blame. The expected self-serving pattern stays the same across contrasting actual behavior. The scenes show no allocation quantities or exact shares.Different behavior, same suspicionIllustrative scenes; no allocation quantities.ExpectedObserved: shared responsibilityExpectedObserved: self-servingCreditBlame
Illustrative scenes: the same cynical expectation sits above shared responsibility and self-serving behavior. The trophy represents credit; the crossed token represents blame. Participants expected others’ allocations, but not their own, to be self-serving whether or not others actually were (Kruger and Gilovich, 1999). Joint holding represents shared responsibility, not equal shares; the scenes are alternatives, not a before-and-after record.

Study source

The teammate and opponent comparison in the last two studies added the moderating finding. Participants assumed their teammates would be less self-serving than their opponents, which the authors read as evidence that lay theories of bias track factors known to affect motivation. The cynicism, in other words, is not indiscriminate; it is aimed at the people who have a stake against you, and it overshoots there.

The paper sits on Ross and Sicoly's 1979 finding. In their first study, both members of 37 married couples separately marked their own share of each of 20 household activities on a line running from primarily the wife to primarily the husband, and on 16 of the 20 the two marks summed to more than the whole. Those couples overclaimed the unwelcome activities too, such as causing arguments, which is what distinguishes an egocentric bias from a self-serving one. Kruger and Gilovich's contribution was to show that people expect a self-serving pattern in others, credit claimed and blame declined, and expect it whether or not the other person's allocations show it. The demo on this page asks how a housemate would split the credit for one good outcome and the blame for one bad one in that spirit; it does not reproduce either paper's procedure.

Everyday examples

The rows below are illustrations of where the expectation of self-serving judgment in others shows up, not findings from the studies cited on this page.

A woman holds out an evenly filled basket from a shared harvest while the man receiving it folds his arms and eyes her with suspicion.
Naive cynicism at a harvest split. The share she is offering is fair, and his own basket is as full as hers. His folded arms say he expected her to keep the best for herself. People tend to assume that others will judge and divide in self-serving ways, more than those others actually do, while seeing their own judgment as the fair one.

Shared credit on a project at workColleagues brace for a grab at the credit and open negotiations by overstating their own partRecord contributions as they happen, before the outcome is known
A disagreement with the other side of a negotiationTheir position is explained by what they stand to gain; yours by the meritsAsk what the merits would look like from their side before assigning a motive
A referee, reviewer or judge who rules against youThe ruling is attributed to bias in your disfavor, a bias that would be invisible if the ruling had gone your wayCheck how often rulings go each way across many cases, not the one you remember
Explaining a stranger's kindnessAn ulterior motive is supplied because self-interest is assumed to be the defaultTreat the kind act as the evidence, and the motive as the thing you do not know

How to counter it

The counter is to check the cynical prediction against what the other person actually says, the step the prediction skips.

  • Ask before you assume. The participants in 1999 predicted a self-serving allocation whether or not their partners had made one. One question would have shown that.
  • Separate egocentric from self-serving. If someone claims a large share of a task, ask whether they also claim a large share of the unpleasant ones. If they do, the pattern is egocentric rather than self-serving, and the usual explanation is memory rather than strategy.
  • Apply the theory to yourself. If you expect the other person to be biased by what they want, your own stake is the same kind of fact about you.
  • Keep records where shares matter. Housework, authorship and credit for sales are all places where a written log replaces two biased memories and two cynical predictions.
  • Notice the teammate exemption. If you trust your own side's judgment and distrust the other side's, the difference is their stake, and a stake is a reason to check, not a verdict.

What it is not

Several biases describe how the self and others are judged differently. Naive cynicism is a belief about other people's bias, not a bias in one's own allocations.

  • It is not egocentric bias, the inflated sense of one's own share of a joint effort. That is the bias Ross and Sicoly documented in couples, and it runs in both directions, for credit and for blame. Naive cynicism is the mistaken expectation that others show a different, self-serving one.
  • It is not the bias blind spot, which is seeing bias in others more readily than in oneself in general. Naive cynicism is a specific instance with a specific content: others are expected to be motivated by self-interest.
  • It is not naive realism, the sense that you see the world as it is, so that disagreement must come from the other person's ignorance or bias. Naive realism reaches the motive after the disagreement appears; naive cynicism supplies it in advance.

Naive Cynicism FAQ

What is naive cynicism?

It is the expectation that other people will judge responsibility in a self-serving way, taking more credit for good outcomes and less blame for bad ones, while you judge fairly, held even when the other people are not in fact self-serving. Kruger and Gilovich named and demonstrated it in 1999 with married couples, video game partners, debaters and darts players. The cynicism is naive because it is applied by default rather than checked.

What is the difference between naive cynicism and egocentric bias?

Egocentric bias is what people actually do: they claim more than their share of a joint activity because their own contributions are easier to remember, and they do it for unwelcome activities as much as welcome ones. Naive cynicism is what people expect others to do: grab credit and shed blame. The 1999 participants predicted the second in others whether or not those others actually showed it. The two are often confused because both end in someone claiming too much.

How does the demo on this page work?

You set four sliders about a good outcome and a bad one that you and the person you live with were equally responsible for: the share of the credit and of the blame they would claim, and the shares you would claim yourself. The result compares the two shares you expected them to claim and reports which was larger. Expecting a bigger share of the credit than of the blame is the self-serving pattern the 1999 participants predicted in their partners. Your own two answers are drawn but not compared.

Does the demo show that I am naively cynical?

No. It shows which of two predictions you made was larger, with the even split for reference. The scenario fixed the facts, an equal share of the work and of the slip, so an uneven prediction is a forecast about how your housemate would judge, not a report of what they did; one forecast measures nothing. The 1999 studies could test the prediction against the partner's actual allocation; the page cannot. It can show you the shape of your expectation, so that you can ask whether it is right.

Why do people expect others to be more self-interested than they are?

Partly because self-interest is a visible, plausible motive and the other person's stake is easy to see. Partly because of a cultural norm: Miller argued in 1999 that people in individualist societies learn to expect self-interest, and Miller and Ratner found in 1998 that people overestimated how much money and group membership drove their peers' attitudes. The expectation tracks motive, which is why teammates were trusted more than opponents in the debating and darts studies.

Is it wrong to be cynical about other people's claims?

It is wrong as a default and sometimes right as a conclusion. Other people's allocations are often biased, but the bias Ross and Sicoly found in couples is egocentric, driven by memory, and it claims blame as readily as credit. Assuming a self-serving motive before checking was what participants did in all four 1999 studies, regardless of whether the partner's allocation was in fact self-serving. The useful habit is to treat the other person's stake as a reason to look at the record, and then to believe the record.
