Dem or Repub? Half of the Answer is in Your Genes

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


A new study from New York University shows that your political preference is more than just a preference: part of it is written in your DNA. “40, perhaps 50 percent of our political beliefs seem to have a basis in genetics,” said Josh Hibbing, political science professor at University of Nebraska, who contributed to the study.

Hibbing’s research showed that identical twins were more likely to share political beliefs than fraternal twins, regardless of how they were raised. But DNA does not “hardwire” the belief itself, it merely affects how a person responds to a given situation. A control-happy neat-freak is far more likely to be a conservative because he or she prefers order and the comfort of the familiar in their life, whereas a touchy-feely, globe-trotting artist is more likely to be a liberal because he or she enjoys new experiences.

But the environment is just a strong a factor as genes, especially when personal security is threatened. Thirty-eight percent World Trade Center survivors, said they grew more conservative after 9/11; only 13 percent said they were more liberal.

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
