People who are one generation removed from subsistence farming are not less intelligent than others. However, they and the family have had a lot less time to view mass media bullshit (tv cable news, internet, etc) and develop the mental callouses necessary to understand the nature of media biases, who owns what media organizations. And in general have had less formal secondary education at the post high school level that teaches critical thinking, skepticism and gain some degree of innoculation against propaganda.
