Brain hacking

In “The Mind’s Biology,” Amy Ellis Nutt reports that some doctors are reaching past the symptoms of mental illness to identify and fix the brain circuits underlie the problems. One of those doctors is Hasan Asif. “Asif says that a person’s mental makeup is a kind of hierarchy, with personality on top, which is created by brain states that arise from circuits firing in a certain pattern below. With psychotherapy, you tweak the brain from the top down, dealing first with a patient’s personality and temperament. But with neurofeedback, combined with qEEG, he said, he tweaks his patients from the bottom up, identifying the brain areas involved and then retraining those circuits to fire differently, resulting in changed moods or mental outlooks.”

Free will and neuroscience

Which happens first … a conscious decision to do something or the brain activity associated with doing it? Thanks to experiments Benjamin Libet conducted in the 1980s, it seemed that “the timing of … conscious decisions was consistently preceded by several hundred milliseconds of background preparatory brain activity.” It seemed, that is, that our brains had already acted to carry out what we only later consciously decided to do.  But in “Neuroscience and Free Will Are Rethinking Their Divorce,” Christian Jarrett says that may be changing. As researcher Dr. John-Dylan Haynes puts it, neuroscience may actually show that “a person’s decisions are not at the mercy of unconscious and early brain waves.”

App addiction

Is it your fault you’re addicted to Facebook, Candy Crush Saga, or whatever? Or are the web and all those apps scientifically designed to break your will? If so, shouldn’t they be regulated? These are questions Michael Schulson addresses in “User Behaviour”: “‘Much as a user might need to exercise willpower, responsibility and self-control, and that’s great, we also have to acknowledge the other side of the street,’ said Tristan Harris, an ethical design proponent who works at Google. (He spoke outside his role at the search giant.) Major tech companies, Harris told me, ‘have 100 of the smartest statisticians and computer scientists, who went to top schools, whose job it is to break your willpower.’”

Choose gratitude

Arthur Brooks explains in “Choose To Be Grateful. It Will Make You Happier.” that it’s up to you whether to be thankful and that you’ll be better off if you choose to do so. “… we are more than slaves to our feelings, circumstances and genes. Evidence suggests that we can actively choose to practice gratitude — and that doing so raises our happiness.”

I watch therefore I am

Seven philosophers discuss seven movies that address some of philosophy’s big questions: How can we do the right thing? What makes a life worth living? Can anything really be justified? Is there more to us than biology? Are the things that we imagine real? What is the enduring self? Is the quest for good a road to evil?
