Liberal Brains Bigger in Areas of Complexity; Conservative Brains Bigger in Areas of Fear

Surprise! A new study says there are brain differences between conservatives and liberals.


This is going to sound sort of obvious, but here we go: A study from University College London published this week in Current Biology has discovered that there are actually differences in the brains of liberals and conservatives. Specifically, liberals' brains tend to be bigger in the area that deals with processing complex ideas and situations, while conservatives' brains are bigger in the area that processes fear.

According to the report: "We found that greater liberalism was associated with increased gray matter volume in the anterior cingulate cortex, whereas greater conservatism was associated with increased volume of the right amygdala."


People with larger amygdalae respond to perceived threats with more aggression and "are more sensitive to threatening facial expressions." The anterior cingulate cortex, however, "monitors uncertainty and conflict." "Thus," says the report, "it is conceivable that individuals with a larger ACC have a higher capacity to tolerate uncertainty and conflicts, allowing them to accept more liberal views."

The London researchers say they're unsure whether the brain's structure causes political views or is the effect of them. Regardless, this puts the "Obama's a Muslim socialist" fearmongering at Tea Party rallies into a whole new light.

Walmart workers issued a "wake up call" to Alice Walton, an heir to the retailer's $500 billion fortune, in New York on Tuesday by marching to Walton's penthouse and demanding her company pay its 1.5 million workers a living wage and give them reliable, stable work schedules.

The protest was partially a response to the company's so-called "Great Workplace" restructuring initiative which Walmart began testing last year and plans to roll out in at least 1,100 of its 5,300 U.S. stores by the end of 2020.
