ArsTechnica:

Granted, it was a small sample size, but those results were encouraging enough to convince Jordan to conduct a more ambitious study over the last four years. His team worked with local farmers in the Okavango delta region, painting the cattle in 14 herds (a total of 2,061 animals). They used acrylic paint (black and white or yellow), applied with foam stencils in the shapes of the inner and outer "eye." The colors were chosen "because of their highly contrasting and aposematic* features, common in natural anti-predator signaling settings," the authors wrote.

Roughly one-third of the cattle in each herd got the eye patterns, one-third got simple cross-marks, and one-third weren't painted at all. The results confirmed Jordan's preliminary findings. Cattle with the painted eyes on their rumps were significantly more likely to survive than those cattle that had crosses painted on their butts and those that weren't painted at all. But the authors were surprised to find that even the painted crosses offered some survival advantage over the unpainted cattle. Over the course of the four-year study, 15 (out of 835) unpainted and four (out of 543) cross-painted cattle were killed by lions; none of the 683 cattle with painted eyes were killed.

The tactic will likely fail to deter the cattle's main predator...

[* Aposematic: conspicuous coloration or markings of an animal serving to warn off predators.]

      Weak correction. RTFA next time before frostpissing

      There are a couple of caveats. First, Jordan acknowledged that there were always unmarked cattle in the herd for their experiments as controls—what he termed "proverbial sacrificial lambs." It's not clear whether applying painted eyes to cow butts would be as effective if all the cows in the herd were painted. He suggests that farmers apply the marks to the most valuable cattle in the herd as the best approach until future research can be done. Second, there is the question of habituation: whether predators will eventually become accustomed to the painted eyes and learn to ignore it as a deterrent.

        Examples of natural eyespots - http://www.bbc.com/earth/story/20141112-six-ways-animals-use-fake-eyes [bbc.com]

        The examples are all due to evolution. If it works well enough most of the time in nature, then it should work well enough most of the time when we use the concept. Of course, nothing is foolproof. SOMETHING kills and consumes all the critters with eyespots!

          Also keep in mind that eyespots work on small birds which aren't as smart as a lion.

        Bullshit.

        The day after they paint on all the cow butts, is the day the wolves ignore the cow butts.

        The fact they left 50% non-painted butts in the same field is the ONLY reason the trick worked.

    Om, nom, nom.

    Just in case any of you were wondering, the Burger Basket in Bells, TN is the best burger by far I've managed to find in the past five and a half years here. And I've been putting significant effort into the search because the burgers around here suck ALL OF THE ASS compared to out in cattle country.

    Most cows with eyes on their butts were identified by local law enforcement face recognition systems as wanted criminals, so they spent most of the evaluation period incarcerated.

    They should actually have experienced a similar level of risk, but the facilities in question had an oddly underrepresented predator population during the study period.

    First, Jordan acknowledged that there were. . .

    Jordan? Jordan Peterson? Canadian of the all Beefeater diet, alone with his insane offspring [theguardian.com]? Now this submission makes sense. Sense about why it was submitted, and why it was accepted, but still nonsense. We could have had a perfectly cromulent aristarchus submission on QAnon, or Oleandrin, or Navy SEAL Breaking Right. But no, we get eyes on cow butts.

    You know, Ancient Greeks, and Phonecians and others, used to paint eyes on the prows of their ships, so the ships could see dangers in advance. And of course, the best example of this in in Milagro Beanfield War [wikipedia.org], where the Sheriff drives out of town, over the painted lines cattle guard, and thinks, "How stupid can cows be!" But then, immediately, he thinks, "What kind of things like this am I falling for?"

    This is a level of self-awareness unavailable to the likes of Runaway, and khallow, and TMB, since they like the Trumpster, and totally wound up in self-interest, and not adequately so. Locus Classicus, however, is a few millennia earlier, in the wisdom of Chuangzi:

    Zhuangzi was wandering in Diaoling fields when he glimpsed a weird magpie-like-thing flying in from the south. It had a wingspan of over seven-feet and passed so close his forehead, he could feel it. Then it gathered its wings and settled in a chestnut grove. Zhuangzi thought “what bird is that? Massive wings of such power and eyes so large it couldn’t see me.” He hiked up his robe and hurriedly tiptoed closer holding his cross-bow at the ready. Then he spotted a cicada settling in the shaded shelter without a worry for itself, but a preying mantis opened its pincers about to grab it, also focused on its gain and ignoring its own bodily danger. The strange magpie burst out and harvested them both—similarly unaware of the natural dangers he faced.

    But Zhuangzi was suddenly seized with this thought, “We natural kinds are all interconnected! We two different species are mutually seeing things in our own ways.” He dismantled his crossbow and fled, himself now himself pursued by the game warden shouting out his crimes.

    From Stanford Encyclopedia of Philosophy [stanford.edu]

    So, be careful, out there, so intent upon your prey, that you do not see that after the Fall of Trump, many will be criminally charged, either for collaboration, conspiracy, or culpable negligence. Many are already coming forward [go.com], to protect themselves. Cockroaches, cockroaches of the God-Imperator!
