In a globalised world, more and more organisations have to select from pools of applicants from different cultures, often by using personality tests. If applicants from different cultures were to differ in the amount of faking on personality tests, this could threaten their validity: Applicants who engage in faking will have an advantage, and will put those who do not fake at a disadvantage. This is the first study to systematically examine and explain cross‐cultural differences in actual faking behavior. In N = 3,678 employees from 43 countries, a scenario‐based repeated measures design (faking vs. honest condition) was applied. Results showed that faking differed significantly across countries, and that it was systematically related to countries’ cultural characteristics (e.g. GLOBE's uncertainty avoidance, future orientation, humane orientation, and in‐group collectivism), but in an unexpected way. The study discusses these findings and their implications for research and practitioners.
