Social media is turning us into thoughtless political extremists

Your Facebook feed is a virtual echo chamber. It serves the same purpose as Fox News or MSNBC.

Big Think Managing Editor Jason Gots recently penned a keen piece on political radicals on Facebook that got me thinking about the ways social media has altered our political rhetoric. At the risk of sounding too much like I'm sucking up to the boss, much of Jason's piece articulated the exact trepidations I feel about my own social media pals:


"There's this disconnect between your Facebook voice (always out for blood) and your in-person voice on those rare occasions when we meet (warm, funny, kind). I'm not saying this is a good thing — the not-talking-explicitly. I just don't like ugly arguments and ad hominem attacks, which I fear (with good reason) is what would happen if I responded to your Facebook posts, which, honestly, have gotten on my nerves to the point where I've hidden them from my News Feed."

Fulfilling the title of his blog — "Overthinking Everything" — Jason delves deeply into the topic. He rallies against the frustrating elements of extremism while questioning how the Facebook radicals of the world would behave should they ever achieve the power they seek. It's an interesting take that's really worth a read. What's that? There's something brown on my nose? I don't know what you're talking about.

The following isn't so much a response to Jason's piece as it is a minor digression or corollary. It began, fittingly, as a Facebook comment in which I attempted to explain why social media (like almost all contemporary media) is bad for political conversation. I should note that I feel the same about irritating conservatives on social media as I do about irritating liberals, though with the caveat that on most issues I lean toward the latter.

Two reasons why social media is bad for us, politically:

1. The echo chamber: I think a huge part of why we've become so divided as a society stems from the binaries mentioned in Jason's piece. Just as conservatives reinforce their anti-liberal sentiments by watching Fox News (and vice-versa with liberals and MSNBC), folks on Facebook curate their audience to form an echo chamber. It's basically self-structured propaganda, which is inherently anti-liberal by the classical definition. Flashier, more inflammatory ideas rise to the top of the conversation thus fueling the sorts of radical biases and heuristics that subconsciously radicalize people. The middle ground shrinks as rhetorical forces seek to push people farther left or farther right. I don't think that's healthy for a society, especially when radicalization comes attached to a sense of mean-spiritedness against the other side.

2. Tactics and tone: The whole public-shaming culture bugs me because it portrays conflicting opinions as, at best, the stupid ramblings of uninformed idiots; at worst, straight-up evil. People act differently online than they do in person, often for the worse, because we see other people online as characters in a larger digital drama rather than real human beings. It engenders a sense of enmity against our peers that ought not have any place in a respectful and democratic society. It also kills me to see people shun, demean, or shame the ignorant, because ignorance is not always the result of volition. Demonization is lazy. It alienates people who might otherwise have come around to your beliefs had they not been made to feel bad. Social media and the SJW mindset (as much as I hate that term) both promote a shouting-down of the opposition rather than a thoughtful attempt to sway opinion. It, by design, divides rather than unites.

3. Memes are the lowest form of political discourse: I mean seriously, come on...



How are we supposed to have deep political discussions when so much of our rhetoric is splashing around in the kiddie pool? This is probably our current era's most chronic ill. Our collective attention spans are so short that most of us only crave shareable, single-serving doses that reflect our own worldview rather than pursue a thorough understanding of how the political world works. And those in the traditional media (who are ostensibly responsible for keeping the public informed) feed those cravings all the way to the bank. Social media isn't necessarily responsible for this (we are), but it's sure not helping things.

Yale scientists restore brain function to 32 clinically dead pigs

Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.

Still from John Stephenson's 1999 rendition of Animal Farm.
Surprising Science
  • Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
  • They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
  • The research raises many ethical questions and puts to the test our current understanding of death.

The image of an undead brain coming back to live again is the stuff of science fiction. Not just any science fiction, specifically B-grade sci fi. What instantly springs to mind is the black-and-white horrors of films like Fiend Without a Face. Bad acting. Plastic monstrosities. Visible strings. And a spinal cord that, for some reason, is also a tentacle?

But like any good science fiction, it's only a matter of time before some manner of it seeps into our reality. This week's Nature published the findings of researchers who managed to restore function to pigs' brains that were clinically dead. At least, what we once thought of as dead.

What's dead may never die, it seems

The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called BrainEx. BrainEx is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.

BrainEx pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs.

The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if BrainEx can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.

As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal.

The researchers hope the technology can enhance our ability to study the brain and its cellular functions. One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions.

"This is an extraordinary and very promising breakthrough for neuroscience. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told National Geographic.

An ethical gray matter

Before anyone gets an Island of Dr. Moreau vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness.

The BrainEx solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness.

Even so, the research signals a massive debate to come regarding medical ethics and our definition of death.

Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?

"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told the New York Times. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."

One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person. They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain.

The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, told Nature that if BrainEx were to become widely available, it could shrink the pool of eligible donors.

"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.

It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.

Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain? The distress of a partially alive brain?

The dilemma is unprecedented.

Setting new boundaries

Another science fiction story that comes to mind when discussing this story is, of course, Frankenstein. As Farahany told National Geographic: "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have Frankenstein, you need some degree of consciousness, some 'there' there. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. But we are one step closer to that possibility."

She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it. The ethical questions, however, remain as unsettling as the stories they remind us of.
