Blue eyes: the allure and the science

Do blue-eyed men truly prefer blue-eyed women? And do brown-eyed men really have no preference? As you might expect, this alleged inclination has to do with securing visible proof of paternity: it's rare for two blue-eyed parents to produce a child with a phenotype of brown eyes (though it can happen). A study published in Norway in 2006 says men with blue-eyes do indeed unconsciously seek out women whose irises are lacking melanin, and explains:

A group of 443 young adults of both sexes and different eye colors were asked to report the eye color of their romantic partners. Blue-eyed men were the group with the largest proportion of partners of the same eye color.

According to Bruno Laeng and colleagues, "It is remarkable that blue-eyed men showed such a clear preference for women with the same eye color, given that the present experiment did not request participants to choose prospective sexual mates, but only to provide their aesthetic or attractiveness responses"¦based on face close-up photographs." Blue-eyed men may have unconsciously learned to value a physical trait that can facilitate recognition of own kin.

Makes enough sense. But what of people with aniridia, or people with heterochromia (like Kate Bosworth, David Bowie, and Christopher Walken)? Might have to resort to Level 4 background checks and straight-up pedigree...In the meantime, here's a fun eye color calculator.

Netflix's Most-Binged Shows of 2017, Ranked

Netflix might know your TV habits better than you do. Recently, the entertainment company's normally tight-lipped number-crunchers looked at user data collected between November 1, 2016 and November 1, 2017 to see which series people were powering through and which ones they were digesting more slowly. By analyzing members’ average daily viewing habits, they were able to determine which programs were more likely to be “binged” (or watched for more than two hours per day) and which were more often “savored” (or watched for less than two hours per day) by viewers.

They found that the highest number of Netflix bingers glutted themselves on the true crime parody American Vandal, followed by the Brazilian sci-fi series 3%, and the drama-mystery 13 Reasons Why. Other shows that had viewers glued to the couch in 2017 included Anne with an E, the Canadian series based on L. M. Montgomery's 1908 novel Anne of Green Gables, and the live-action Archie comics-inspired Riverdale.

In contrast, TV shows that viewers enjoyed more slowly included the Emmy-winning drama The Crown, followed by Big Mouth, Neo Yokio, A Series of Unfortunate Events, GLOW, Friends from College, and Ozark.

There's a dark side to this data, though: While the company isn't around to judge your sweatpants and the chip crumbs stuck to your couch, Netflix is privy to even your most embarrassing viewing habits. The company recently used this info to publicly call out a small group of users who turned their binges into full-fledged benders:

Oh, and if you're the one person in Antarctica binging Shameless, the streaming giant just outed you, too.

Netflix broke down their full findings in the infographic below and, Big Brother vibes aside, the data is pretty fascinating. It even includes survey data on which shows prompted viewers to “Netflix cheat” on their significant others and which shows were enjoyed by the entire family.
