Any study that related intelligence to opinion is inherently inflammatory. It invites dismissiveness instead of engagement, excuses rude behavior, and presumes that certain opinions are so dumb the holder is incapable of growth.

Consider that intelligence is difficult to define or measure - for instance, urbanites can’t tell the difference between a yellow jacket and a dirty dobber. That qualifies as stupid on some life tests. These are just two logical example of how confounding variables might lead to inaccurate and sloppy findings.
