Does this relate to what we observe in debate and elsewhere?
Analyzing the results, the researchers found that people with both relatively higher and lower levels of cognitive ability show approximately equal levels of intergroup bias, but towards different sets of groups.
People with low cognitive ability tended to express prejudice towards groups perceived as liberal and unconventional (e.g., atheists, gays and lesbians), as well as groups of people perceived as having low choice over group membership (e.g., ethnic minorities).
People with high cognitive ability showed the reverse pattern. They tended to express prejudice towards groups perceived as conservative and conventional (e.g., Christians, the military, big business).
