First, let's take a look at the liberal brain. Studies have found that, on average, the brains of liberals have greater volume in a region known as the anterior cingulate cortex (ACC). This area has been linked to several functions, including conflict detection, which enables us to regulate our behavior by identifying discrepancies between instinctual, habit-driven impulses and our actual intentions. So whether you're swerving to dodge a deer that's abruptly run onto the road, or halting before eating that one rotten grape from the fruit bowl, you can thank your ACC for its conflict detection capabilities.
Beyond its greater size, the ACC of the liberal brain also fires more frequently while detecting these differences between instinct and intention. In a political context, this may enable liberals to approach policy issues with greater sensitivity to when their habitual tendencies are ill suited for addressing the issue at hand.
The conservative brain, on the other hand, has greater volume in a region called the amygdala, an almond-shaped structure implicated in emotional and fear-based learning. In one study, researchers found that when conservatives hear shocking noise stimuli, such as a blast of white noise, they exhibit more fearful instinctual reactions as measured by blink response, an indicator of amygdala activity. These findings have led some to speculate that larger and more sensitive amygdalae in conservatives may cause them to be more driven by fear and emotional rewards.
