Why Online Comments are So Polarized

In this five-minute video, Ze Frank posits a theory about why online comments are so overwhelmingly positive or negative. Ze is a guy who has done tons of work online (primarily video, but also interactive group projects), and is currently posting videos several times a week, many of which receive lots of feedback...and most of that feedback is hyper-polarized, loving or hating, to the point that one commenter recently suggested he'd like to punch Ze in the face because Ze's voice is so annoying. As a fellow guy who makes internet things and posts them every day, I can relate to this issue -- though I don't recall the comments ever getting super nasty here on Mental Floss (y'all are great; it's the YouTube commenters who scare me). So, if you have five minutes to think about why online comments are what they are, and what we should and should not do about it, here's Ze Frank's "Face Punch":

Sample quote: "A lot of people have violent thoughts, and as long as those thoughts stay thoughts, and they don't become obsessive, it's actually pretty normal. ... I think of those punch-you-in-the-face comments as somewhere in between thinking a thing and saying it in public."

Can You Figure Out This Newly Discovered Optical Illusion?
Kohske Takahashi, i-Perception (2017)
Kohske Takahashi, i-Perception (2017)

Ready to have your mind boggled? Take a look at the image above. What shape are the lines? Do they look like curves, or zigzags?

The image, spotted by Digg, is a new type of optical illusion published in the aptly named journal i-Perception. Discovered by Japanese psychologist Kohske Takahashi, it’s called the “curvature blindness illusion,” because—spoiler—the contrast of the lines against the gray background makes our eye see some of the lines as zigzags when, in fact, they’re all smooth curves.

The illusion relies on a few different factors, according to the three experiments Takahashi conducted. For it to work, the lines have to change contrast just at or after the peak of the curve, reversing the contrast against the background. You’ll notice that the zigzags only appear against the gray section of the background, and even against that gray background, not every line looks angled. The lines that look curvy change contrast midway between the peaks and the valleys of the line, whereas the lines that look like they contain sharp angles change contrast right at the peak and valley. The curve has to be relatively gentle, too.

Go ahead, stare at it for a while.

Vivid Imagery Makes Poetry More Pleasurable, According to Psychologists

Contrary to what English teachers led us to believe, most readers don’t judge poetry based on factors like alliteration and rhyme. In fact, a new study published in the journal Psychology of Aesthetics, Creativity, and the Arts suggests that vivid imagery (i.e. sense-evoking description) is what makes a poem compelling, according to Smithsonian.

To determine why some poetic works are aesthetically pleasing while others are less so, researchers from New York University and the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany, had more than 400 online volunteers read and rate 111 haikus and 16 sonnets. Participants answered questions about each one, including how vivid its imagery was, whether it was relaxing or stimulating, how aesthetically pleasing they found it, and whether its content was positive or negative.

Not surprisingly, taste varied among subjects. But researchers did find, overall, that poems containing colorful imagery were typically perceived as more pleasurable. (For example, one favorite work among subjects described flowers as blooming and spreading like fire.) Emotional valence—a poem's emotional impact—also played a smaller role, with readers ranking positive poems as more appealing than negative ones. Poems that received low rankings were typically negative, and lacked vivid imagery.

Researchers think that vivid poems might also be more interesting ones, which could explain their popularity in this particular study. In the future, they hope to use similar methodology to investigate factors that might influence our enjoyment of music, literature, and movies.
