If we, as users, are unaware that our brains respond to variable rewards with a sure-fire release of happy hormones, then we are, of course, no match for the cybertech industry with its accumulated insights. As Harris explains, “With variable rewards, I’m pulling a lever and sometimes I get a juicy reward (ooh, exciting!) and other times I don't.” Let’s have a look at just one example of how our most primitive brain functions can be used against us. When checking our virtual inbox every few minutes, swiping up or down to refresh, what we’re always hoping for is a “reward.” Can you honestly call this a conscious use of communications technology? And are we really deciding for ourselves how we spend our time? If you ask Tristan Harris and many other researchers, the answer is a resounding no.
“Video streaming services, networking apps and news portals are all competing for our attention,” says Harris. This is the crux of the problem. After all, technology does not develop at random. Each innovation is one competitor’s response to another’s innovation. The rapid spread of fake news is one of the unfortunate side effects of this vicious cycle. “Anger boosts screentime far more effectively than contentment,” says Harris. We share the things that upset us with more friends, research them on more channels and go on consuming them obsessively. The relevant algorithms pick up on this. And keep feeding us more distressing content. While it need not always be fake news, one thing is for sure: It’s not the accuracy of the content that determines what appears on our pinboards and timelines. “Remember that a personalized newsfeed is not generated by people, but by algorithms,” adds Harris. “And they are not programmed to deliver what’s right or healthy for us, but instead what holds our attention for longer.”
