GAB is pleased to reprint the article below from Vox Ukraine Idea, an independent analytical platform dedicated to helping Ukraine move into the future. Authors Professor Yuriy Gorodnichenko of the University of California, Berkeley, and Ilona Sologoub, Vox Ukraine’s Scientific Editor, have taken a major step forward in explaining how policymakers can manage the vexed and misunderstood issue of corruption perception measures.
In March 2026, Ukrainians reported that corruption was the second most important problem after the war. 12% of people even put it in the first place. Between 70% and 90% of Ukrainians believe that corruption is a serious problem. At the same time, the incidence of corruption was much lower: in 2025, between 5% (in administrative services) and 32% (in the construction sector) of people found themselves in situations where a bribe was necessary to address their issues. This divergence between perceived and experienced corruption has been persistent: the gap has reached 60-70 percentage points at least since the early 2000s, when the data became available.
This situation is not unique to Ukraine. In many countries, perceived corruption differs from experienced corruption. Furthermore, when objective measures of corruption are available (Sarullo et al. 2026), they are only weakly correlated with perceptions. One explanation is that surveys measure only petty corruption, whereas perceptions of grand corruption are shaped by the media. Consistent with this explanation, freedom of speech is related to perceived corruption (Gutmann et al. 2020, Costa 2013). This can lead to the integrity paradox: more information about officials prosecuted for corruption can increase popular beliefs about the extent of corruption in a country.
How can one then defeat the corruption narrative?
