I'm afraid the title could be misread as "I'm tolerant so I'm more clever than you" or "the population of democratic nations are more intelligent than nondemocratic". All of that is obviously bullshit if you give it 2s of thoughts. That being said, democratic countries typically focus greatly on 1/ free speech (a driver of diversity) and 2/ education, which certainly is a good driver for cognitive ability, and might very well be a good driver for tolerance as well.
