People Who Understand Evolution Are More Likely to Accept It

Even among the religious and conservative, knowledge of the theory influenced belief

Science denialism can seem intractable, and studies on the topic are seldom encouraging. For example, research out of Yale Law School suggests that when people form their opinions on contentious topics such as climate change or evolution, political or religious values trump knowledge of the concept.

A study published in March in BioScience begs to differ, at least when it comes to evolution. Researchers at the University of Pennsylvania and their colleagues measured participants' knowledge of evolutionary theory, as well as their acceptance of evolution as fact. They found a significant link between understanding the fine points of the theory and believing in it, regardless of religious or political identity.

Unlike earlier research that involved only high school or college students, the demographics of the 1,100 subjects in the new study better approximated those of the overall U.S. population. The researchers also used more nuanced language in their questions to distinguish between subjects' intellectual grasp of evolution and their personal feelings toward it. It remains unclear whether science education leads directly to increased acceptance of evolution, but the Penn study supports this possibility.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
