If the sight of Swiss cheese makes you melt or the thought of a honeycomb gets you buzzing, you may suffer from trypophobia, the most common phobia that you've probably never heard of. Trypophobia is the fear of holes. People with the phobia experience panic attacks, increased heart rate and hot sweats when they see clusters of holes.
 
A visual scientist who suffers from trypophobia decided to investigate the phenomenon with his colleague. They performed spectral analysis on images that induce trypophobia and found that the fear-inducing images all had similar characteristics related to luminescence, contrast and light wavelengths. But they didn’t know why these features caused such an adverse reaction.
 
A study participant mentioned that certain animals also induced his phobia. So the researchers analyzed pictures of poisonous animals.
 
They discovered that the trypophobia-inducing images and those of poisonous animals shared the same visual features, suggesting the fear may be an evolutionary survival response. The study is in the journal Psychological Science. [Geoff G Cole and Arnold J Wilkins, Fear of holes
 
So if an english muffin induces a panic attack, your brain may just be saying better safe than sorry.

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
