On manipulating memories, we're not as far behind Hollywood as you might think

Deep brain stimulation is racing ahead, and the ethical issues associated with it are starting to be debated.

Remember Total Recall? When the film came out in 1990, its premise, in which people take virtual holidays using memory manipulation, seemed farfetched. But on 20 August President Obama’s commission on bioethics debated what we ought to do about memory manipulation. That’s because it is just one of many invasive actions we are beginning to perform on the brain.
 
This month, the first trials of a new technique for controlling Parkinson’s disease began. A German sufferer has had a “deep brain stimulation” device, essentially a pair of electrodes, implanted in his brain. It will monitor the brain’s activity to deliver electrical currents designed to combat tremors and muscle rigidity. A similar technique has been shown, in a few cases, to reverse the shrinkage of brain tissues associated with Alzheimer’s disease. This reversal was not only about the neural tissue’s physical appearance: it led to improved brain functioning. No one knows how it works; the best guess is that it stimulates the growth of neurons.
 
Deep brain stimulation is also a treatment option if you have obsessive compulsive disorder. OCD appears to arise when electrical circuits conveying signals between the emotional and the decision-making parts of the brain become stuck in feedback loops. That leads to people compulsively repeating actions because the anxieties associated with not having done the task don’t get erased. A jolt of electricity seems to clear the brain jam, however. Similar treatments seem to be a cure for depression in some people.
 
And, true to Hollywood, we are now manipulating memories. We’re not yet at the virtual holiday stage, but mice are starting to have some strange experiences. Last month it was reported that electricity delivered to a mouse’s hippocampus gave it a memory of receiving a shock to the foot.
 
Hence the need for ethical review: it is easy to see how this could eventually be used to create a tool for controlling errant prisoners, say, or mental-health patients. Perhaps you remember the electroconvulsive “therapy” punishment in One Flew Over the Cuckoo’s Nest? It’s still seen as a treatment option for depression but some think it’s too blunt an instrument. Deep brain stimulation is far less blunt – yet who decides just how blunt is acceptable?
 
There are many other issues to face. As we begin our assault on the brain, we will begin to gather information that might turn out to be problematic. Brain experiments are already suggesting that some people have naturally poor control over impulsive actions, and are more prone to criminal or antisocial behaviour. It is important that such information should not get thrown casually into the public sphere.
 
For all the appropriate caution, let’s acknowledge that some of the things we’re learning to do to the brain are really rather exciting. Having a virtual holiday might sound like a bore, but what about having razor-sharp focus at the flick of a switch? The US military is piloting a scheme that is mind-bendingly futuristic: a DC electrical current applied to the brain that in effect puts you into a high-concentration zone. With “transcranial direct current stimulation”, learning is accelerated and performance in tasks that require mental focus is significantly enhanced.
 
The Americans are using it to improve sniper training but that won’t be the only application. One day soon you might unplug yourself and utter the immortal words: “I know kung fu.” Hollywood races ahead, but we’re not as far behind as you might think.

Fark.com’s censorship story is a striking insight into Google’s unchecked power

The founder of the community-driven website claims its advertising revenue was cut off for five weeks.

When Microsoft launched its new search engine Bing in 2009, it wasted no time in trying to get the word out. By striking a deal with the producers of the American teen drama Gossip Girl, it made a range of beautiful characters utter the words “Bing it!” in a way that fell clumsily on the audience’s ears. By the early Noughties, “search it” had already been universally replaced by the words “Google it”, a phrase that had become so ubiquitous that anything else sounded odd.

Like Hoover and Tupperware before it, Google’s brand name has now become a generic term.

Yet only recently have concerns about Google’s pervasiveness received mainstream attention. Last month, The Observer ran a story about Google’s auto-fill pulling up the suggested question of “Are Jews evil?” and giving hate speech prominence in the first page of search results. Within a day, Google had altered the autocomplete results.

Though the company’s response may seem promising, it is important to remember that Google isn’t just a search engine (Google’s parent company, Alphabet, has too many subdivisions to mention). Google AdSense is an online advertising service that allows many websites to profit from hosting advertisements on its pages, including the New Statesman itself. Yesterday, Drew Curtis, the founder of the internet news aggregator Fark.com, shared a story about his experiences with the service.

Under the headline “Google farked us over”, Curtis wrote:

“This past October we suffered a huge financial hit because Google mistakenly identified an image that was posted in our comments section over half a decade ago as an underage adult image – which is a felony by the way. Our ads were turned off for almost five weeks – completely and totally their mistake – and they refuse to make it right.”

The image was of a fully-clothed actress who was an adult at the time, yet Curtis claims Google flagged it because of “a small pedo bear logo” – a meme used to mock paedophiles online. More troubling than Google’s decision, however, is the difficulty that Curtis had contacting the company and resolving the issue, a process which he claims took five weeks. He wrote:

“During this five week period where our ads were shut off, every single interaction with Google Policy took between one to five days. One example: Google Policy told us they shut our ads off due to an image. Without telling us where it was. When I immediately responded and asked them where it was, the response took three more days.”

Curtis claims that other sites have had these issues but are too afraid of Google to speak out publicly. A Google spokesperson says: "We constantly review publishers for compliance with our AdSense policies and take action in the event of violations. If publishers want to appeal or learn more about actions taken with respect to their account, they can find information at the help centre here.”

Fark.com has lost revenue because of Google’s decision, according to Curtis, who sent out a plea for new subscribers to help it “get back on track”. It is easy to see how a smaller website could have been ruined in a similar scenario.

Google’s decision was not sinister, and it is obviously important that it tackles things that violate its policies. The lack of transparency around such decisions, and the difficulty getting in touch with Google, are troubling, however, as much of the media relies on the AdSense service to exist.

Even if Google doesn’t actively abuse this power, it is disturbing that it has the means by which to strangle any online publication, and worrying that smaller organisations can have problems getting in contact with it to solve any issues. In light of the recent news about Google's search results, the picture painted becomes more even troubling.

Update, 13/01/17:

Another Google spokesperson got in touch to provide the following statement: “We have an existing set of publisher policies that govern where Google ads may be placed in order to protect users from harmful, misleading or inappropriate content.  We enforce these policies vigorously, and taking action may include suspending ads on their site. Publishers can appeal these actions.”
