Brain Boosting Machine Works. But Is it Ethical?

A simple and cheap device that stimulates the brain with a mild electric current appears to improve our capacity to learn skills like mathematics or a foreign language. Should we use it?

What's the Latest Development?


A small machine developed at Oxford University could help improve your language and maths abilities, memory, attention and even movement. The device, called a transcranial direct current stimulation, uses electrodes placed outside the head to run a mild electric current through the brain for about 20 minutes. Experimental psychologist Dr. Roi Cohen Kadosh says: "I can see a time when people plug a simple device into an iPad so that their brain is stimulated when they are doing their homework, learning French or taking up the piano." 

What's the Big Idea?

The Oxford psychologists were also concerned with the ethics of their brain boosting machine. By all accounts, they say, if the machine is proven safe, it should be distributed widely to augment basic human capabilities. "This technology overcomes some standard objections to enhancement: It is not a set of cheat notes," says Professor Julian Savulescu. "You require effort and hard work to learn. It is just that you get more out of your effort. And because it is cheap, low tech, easily affordable, it could be widely available."

Politics & Current Affairs

For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
