Conservatism and cognitive ability are negatively correlated

From the journal Intelligence, Volume 37, Issue 3, May-June 2009, Pages 294-304:

Conservatism and cognitive ability are negatively correlated

Lazar Stankov

Available online 3 February 2009.

Abstract

Conservatism and cognitive ability are negatively correlated. The evidence is based on 1254 community college students and 1600 foreign students seeking entry to United States’ universities. At the individual level of analysis, conservatism scores correlate negatively with SAT, Vocabulary, and Analogy test scores. At the national level of analysis, conservatism scores correlate negatively with measures of education (e.g., gross enrollment at primary, secondary, and tertiary levels) and performance on mathematics and reading assessments from the PISA (Programme for International Student Assessment) project. They also correlate with components of the Failed States Index and several other measures of economic and political development of nations. Conservatism scores have higher correlations with economic and political measures than estimated IQ scores.
