Why Do People Feel Phantom Cellphone Vibrations?

Jason's Phone

Let’s picture a typical moment in my day: I’m minding my own business, with my iPhone in my back pocket. Suddenly, my left cheek is shaking as the phone vibrates and does the bzzt, bzzt, bzzt-ing dance of its people on my backside. I check the phone, and there’s nothing. No call. No text. No email. No one has moved in Words With Friends or liked my pictures on Instagram. Nothing that would have made the phone vibrate, but I swear I felt it.

I don’t suffer these mysterious vibrations alone. In one study into the phenomenon - variously dubbed “phantom ringing,” “phantom vibration syndrome” and vibranxiety - phantom phone vibrations were experienced by 68% of the people surveyed, with 87% of those feeling them weekly, and 13% daily.

What is it that plagues our pockets?

The phantom vibrations have only recently gotten the attention of scientists, and while they’ve offered up opinions and hypotheses, peer-reviewed research on the ghostly buzzes is scarce.

Alex Blaszczynski, chairman of the School of Psychology at the University of Sydney, thinks the vibrating sensation is triggered by electrical activity. "I expect it's related to some of the electrical signals coming through in a transmission, touching on the surrounding nerves, giving a feeling of a vibration,” he told the Sydney Morning Herald, with the caveat that he hasn’t conducted any studies on the vibrations. If he’s right, it would mean vibes are not phantom, but a real sensation - a physical stimulation similar to what happens when your phone is near a speaker and you hear that weird buzzing sound as it does a "hand shake" with a cell tower and gives off some electromagnetic interference.

Anticipation

Larry Rosen, a professor of psychology at California State University offers a different idea in his book, iDisorder. He says that since we’re almost always anticipating some sort of technological interaction, especially with our smartphones, we inevitably interpret some unrelated stimuli, like our pants rubbing against our leg or a chair dragging against the floor, as a phone call.

The only published study on phantom vibrations that we were able to find focused on gauging vibranxiety’s prevalence, and didn’t examine the cause. But the researchers offered an educated guess similar to Rosen’s. Michael Rothberg, a clinician investigator at Baystate Medical Center in Springfield, Massachusetts, who conducted the survey mentioned earlier, says that vibranxiety might be caused by the misinterpretation of sensory signals in our brain.

“In order to deal with an overwhelming amount of sensory input,” Rothberg and his team say in their study, “the brain applies filters or schema based on what it expects to find, a process known as hypothesis guided search.” With the phantom vibrations, the brain sometimes misinterprets sensory input according to the preconceived hypothesis that a vibrating sensation will be coming from the phone. In other words, it seems smartphone users are just so primed for, and attentive to, the sensation of their phone going off that they simply experience the occasional false alarm.

Make It Stop!

Phantom vibrations don’t appear to cause any harm, but if the mild annoyance is too much for you, they can be stopped. Thirty-nine percent of the people in Rothberg’s survey - all medical staff who had a phone or pager on them all day - were able to stop the vibrations either by taking the device off vibrate mode and using the audible ringer, changing the location of the device on their person, or using a different device (success rates were 75%, 63% and 50%, respectively).

Big Questions
Why Don't We Eat Turkey Tails?

Turkey sandwiches. Turkey soup. Roasted turkey. This year, Americans will consume roughly 245 million birds, with 46 million being prepared and presented on Thanksgiving. What we don’t eat will be repurposed into leftovers.

But there’s one part of the turkey that virtually no family will have on their table: the tail.

Despite our country’s obsession with fattening, dissecting, and searing turkeys, we almost inevitably pass up the fat-infused rear portion. According to Michael Carolan, professor of sociology and associate dean for research at the College for Liberal Arts at Colorado State University, that may have something to do with how Americans have traditionally perceived turkeys. Consumption was rare prior to World War II. When the birds were readily available, there was no demand for the tail because it had never been offered in the first place.

"Tails did and do not fit into what has become our culinary fascination with white meat," Carolan tells Mental Floss. "But also from a marketing [and] processor standpoint, if the consumer was just going to throw the tail away, or will not miss it if it was omitted, [suppliers] saw an opportunity to make additional money."

Indeed, the fact that Americans didn't have a taste for tail didn't prevent the poultry industry from moving on. Tails were being routed to Pacific Island consumers in the 1950s. Rich in protein and fat—a turkey tail is really a gland that produces oil used for grooming—suppliers were able to make use of the unwanted portion. And once consumers were exposed to it, they couldn't get enough.

“By 2007,” according to Carolan, “the average Samoan was consuming more than 44 pounds of turkey tails every year.” Perhaps not coincidentally, Samoans also have alarmingly high obesity rates of 75 percent. In an effort to stave off contributing factors, importing tails to the Islands was banned from 2007 until 2013, when it was argued that doing so violated World Trade Organization rules.

With tradition going hand-in-hand with commerce, poultry suppliers don’t really have a reason to try and change domestic consumer appetites for the tails. In preparing his research into the missing treat, Carolan says he had to search high and low before finally finding a source of tails at a Whole Foods that was about to discard them. "[You] can't expect the food to be accepted if people can't even find the piece!"

Unless the meat industry mounts a major campaign to shift American tastes, Thanksgiving will once again be filled with turkeys missing one of their juicier body parts.

Why Do We Dive With Sharks But Not Crocodiles?

Why do we dive with sharks but not crocodiles?

Eli Rosenberg:

The issue is the assumption that sharks' instincts are stronger and more basic.

There are a couple of reasons swimming with sharks is safer:

1. Most sharks do not like the way people taste. They expect their prey to taste a certain way, like fish/seal, and we do not taste like that. Sharks also do not like the sensation of eating people. Bigger sharks like great whites enjoy prey with a high fat-bone ratio like seals. Smaller sharks enjoy eating fish, which they can gobble in one bite. So, while they might bite us, they pretty quickly decide “That’s not for me” and swim away. There is only one shark that doesn’t really care about humans tasting icky: that shark is our good friend the tiger shark. He is one of the most dangerous species because of his nondiscriminatory taste (he’s called the garbage can of the sea)!

2. Sharks are not animals that enjoy a fight. Our big friend the great white enjoys ambushing seals. This sneak attack is why it sometimes mistakes people for seals or sea turtles. Sharks do not need to fight for food. The vast majority of sharks species are not territorial (some are, like the blacktip and bull). The ones that are territorial tend to be the more aggressive species that are more dangerous to dive with.

3. Sharks attacked about 81 people in 2016, according to the University of Florida. Only four were fatal. Most were surfers.

4. Meanwhile, this is the saltwater crocodile. The saltwater crocodile is not a big, fishy friend, like the shark. He is an opportunistic, aggressive, giant beast.


5. Crocodiles attack hundreds to thousands of people every single year. Depending on the species, one-third to one-half are fatal. You have a better chance of survival if you played Russian roulette.

6. The Death Roll. When a crocodile wants to kill something big, the crocodile grabs it and rolls. This drowns and disorients the victim (you). Here is a PG video of the death roll. (There is also a video on YouTube in which a man stuck his arm into an alligator’s mouth and he death rolled. You don’t want to see what happened.)

7. Remember how the shark doesn’t want to eat you or fight you? This primordial beast will eat you and enjoy it. There is a crocodile dubbed Gustave, who has allegedly killed around 300 people. (I personally believe 300 is a hyped number and the true number might be around 100, but yikes, that’s a lot). Gustave has reportedly killed people for funsies. He’s killed them and gone back to his business. So maybe they won’t even eat you.


8. Sharks are mostly predictable. Crocodiles are completely unpredictable.

9. Are you in the water or by the edge of the water? You are fair game to a crocodile.

10. Crocodiles have been known to hang out together. The friend group that murders together eats together. Basks of crocodiles have even murdered hippopotamuses, the murder river horse. Do you think you don't look like an appetizer?

11. Wow, look at this. This blacktip swims among the beautiful coral, surrounded by crystal clear waters and staggering biodiversity. I want to swim there!

Oh wow, such mud. I can’t say I feel the urge to take a dip. (Thanks to all who pointed this out!)

12. This is not swimming with the crocodiles. More like a 3D aquarium.
