Wired's Clive Thompson's latest column probes the new bioethical conundra of "cognitive liberty" -- the freedom not to have our brains scanned. I first encountered the phrase in relation to mind-altering drugs, where it's also a good fit -- what freedom could be more fundamental than the freedom to choose your state of mind?
We think of our brains as the ultimate private sanctuary, a zone where other people can't intrude without our knowledge or permission. But its boundaries are gradually eroding. Hypersonic sound is just a portent of what's coming, one of a host of emerging technologies aimed at tapping into our heads. These tools raise a fascinating, and queasy, new ethical question: Do we have a right to "mental privacy"?
"We're going to be facing this question more and more, and nobody is really ready for it," says Paul Root Wolpe, a bioethicist and board member of the nonprofit Center for Cognitive Liberty and Ethics. "If the skull is not an absolute domain of privacy, there are no privacy domains left." He argues that the big personal liberty issues of the 21st century will all be in our heads – the "civil rights of the mind," he calls it.
It's true that most of this technology is still gestational. But the early experiments are compelling: Some researchers say that fMRI brain scans can detect surprisingly specific mental acts – like whether you're entertaining racist thoughts, doing arithmetic, reading, or recognizing something. Entrepreneurs are already pushing dubious forms of the tech into the marketplace: You can now hire a firm, No Lie MRI, to conduct a "truth verification" scan if you're trying to prove you're on the level. Give it 10 years, ethicists say, and brain tools will be used regularly – sometimes responsibly, often shoddily.

To demonstrate the Magnus effect, YouTuber PeterSripol grabbed a couple of KFC buckets and tricked out an RC plane. The resulting trial and error is mostly the latter.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
