Researchers have found that during conversations, left-leaning people were more likely to follow the other person’s “eye cues” than conservatives. Let’s say you are having a conversation with someone and you suddenly take your gaze off them to look at something slightly to the right, say a cute person or a passing zebra. Liberals are more likely to follow your gaze and look as well, even if what you are looking at has no bearing on the conversation. If you look away again, they will follow your gaze again, and so on and so on, like two little puppies distracted by shiny passing balloons.
Conservatives are almost never going to follow your gaze, but will continue looking straight at you, like robots. Those conducting the study speculated that conservatives held their gaze because, no lie, they don’t like being told what to do.
