New technique brings us one step closer to mind reading
Canadian researchers have successfully reconstructed faces from data in brain scans.
In 1930, Upton Sinclair’s wife, Mary, was experiencing serious depression. The couple became dedicated to the occult during this time; Upton believed Mary to have psychic abilities. His resulting book, Mental Radio, documented the tests he administered to test her mind-reading skills.
Sinclair published many important books across multiple genres, most famously The Jungle, which changed how Americans view the meatpacking industry—today’s vegetarian movement has his investigative journalism to thank. But Mental Radio was not received well. After he initially self-published the book, critics denounced his work as not serious science (there was no control; it was not a double-blind study) and for expressing an uncritical faith in telepathy.
Clairvoyance has never done well in clinical settings, yet that has not stopped an entire contingent of mediums and psychics from claiming to possess such skills. Even Sinclair’s data expresses little more than chance, but considering the circumstances he likely wanted to believe his hypothesis to be true, perhaps as a way of helping his wife deal with her psychological disorder.

Telepathy in the traditionally used sense is suspect—the notion I can “see” inside your brain and pick out thoughts or images. We're so fascinated with telepathy some had faith in an octopus named Paul predicting the winner of World Cup games. This is different from intuition, whose mechanisms are better understood. A hunch has a basis in observation skills and psychology. Outright mind reading, especially across space and time, has never yielded positive results.
Maybe we need to redefine what mind reading entails. At least that’s the consensus from a team of neuroscientists at the University of Toronto Scarborough, which recently reconstructed images based on data gathered from EEG scans. The study, published in eNeuro, could have broad implications in our understanding of how we construct images and remember events, or, in this case, faces.
The recognition of faces is an important social skill that relies upon near-instantaneous visual processing. The researchers wanted to find out if they could reconstruct faces from neural data provided by brain scans. As they conclude in their study, “the present work accounts for the time course of face individuation through appeal to its underlying visual representations while, also, it provides a first demonstration regarding the ability to reconstruct the appearance of stimulus images from electroencephalography data.”
For the study, thirteen healthy adults—six males, seven females, between the ages of 18-27—with normal vision were shown 140 images of seventy individuals. Their brain activity was recorded and used to reconstruct the faces based on the machine’s algorithms. While similar studies have been conducted using fMRI, that method is more expensive and requires more equipment. fMRI also captures images over seconds, while EEG registers information in milliseconds.

As postdoctoral fellow Dan Nemrodov, who developed this technique, says, “When we see something, our brain creates a mental percept, which is essentially a mental impression of that thing. We were able to capture this percept using EEG to get a direct illustration of what’s happening in the brain during this process.”
This could provide an important step forward in our justice system, as law enforcement officials will be able to better construct faces from data collected through scans of victims’ brains. As assistant professor Adrian Nestor, whose lab Nemrodov works in, states,
“What’s really exciting is that we’re not reconstructing squares and triangles but actual images of a person’s face, and that involves a lot of fine-grained visual detail. The fact we can reconstruct what someone experiences visually based on their brain activity opens up a lot of possibilities. It unveils the subjective content of our mind and it provides a way to access, explore and share the content of our perception, memory and imagination.”
Though we might not have discovered the mind palace yet, this fascinating breakthrough brings us one step closer to understanding the mechanisms of consciousness. The applications of this technique will be limited only by our imagination, which we are now also closer to understanding. So the next time you visit a psychic, ask for their EEG machine. That way you might actually get what you pay for.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
