A meta-analysis of dispositional optimism levels as measured by the life orientation test (LOT, Scheier & Carver, 1985) across 22 countries (k = 213; N = 89,138) is reported. Using mixed effect modeling, overall culture differences were small. Greater individualism (Hofstede, 1980) was associated with greater optimism. Greater egalitarianism (versus hierarchy, Schwartz, 1994) was consistently associated with higher optimism. Claims of fundamental cultural differences were not supported. Implications for cross-cultural research and applications are discussed.
