A common intuition about corruption is that individuals are more likely to engage in corruption when they witness others committing corrupt acts without facing serious consequences—in other words, a “culture of corruption” can be self-perpetuating (see here and here), and the perception or belief that corruption is widespread can itself be a cause of corruption. While compelling, this intuition has not been subjected to much empirical scrutiny. While there does seem to be some evidence of an association between individuals’ perceptions of the prevalence of domestic corruption and those individuals’ inclination to act corruptly, the research on this topic is relatively thin.
In a recent paper, a group of academics (Israel Waismel-Manor, Patricia Moy, Rico Neumann, and Moran Shechnick) weighed in, presenting the results of a controlled lab experiment that sought to assess whether news about corruption by public officials affected individuals’ incentives to behave dishonestly. The study was conducted in Israel, and participants were required first to watch a short television news segment. The treatment group’s segment revolved around an Israeli mayor suspected of certain corrupt acts, while the control group’s segment was unrelated to corruption. The participants were also given a short quiz about the segment they’d seen, and half of the participants in each group were offered a monetary reward if they answered all the questions correctly; they were told “to answer all questions from memory” and not look anything up on the internet. However, unbeknownst to the participants, one of the questions could not be answered without doing additional searches, so the researchers could use the answer to this question to identify those participants who cheated on the test. The real goal of the study (of which participants were not aware) was to see whether exposure to the corruption news story (alone or in combination with the financial incentive) affected participants’ likelihood of cheating.
Unsurprisingly, participants who were offered money for answering all questions correctly cheated far more often, regardless of which news story they watched. The study’s authors seem to have expected that those participants who watched the corruption-related story would also cheat more (holding constant whether they had financial incentives to answer questions correctly). But this did not occur: Participants who watched the news segment involving a mayor suspected of corruption did not cheat in statistically significantly higher rates than those who watched the other, unrelated-to-corruption segment. The researchers suggested that perhaps the reason was that Israelis had been inundated with so much news about official corruption around the time of the experiment (which took place in 2019), particularly in connection with the investigation and prosecution of Prime Minister Benjamin Netanyahu and other senior politicians (see here, here, and here), that the marginal impact of exposure to additional news about corruption, in the form of this one story, would not have much impact.
While that explanation is plausible, I have some other concerns about the research’s design and methodology, which make me question whether this experiment was in fact a good way to assess the “culture of corruption” hypothesis.
