Brain Porn

This article by Sally Satel really hit the nail on the head for me by articulating some fMRI feelings I’ve had more eloquently than I could do myself. Brain scans are undoubtedly pretty:

And the idea that we might be able to understand what’s going on when we have certain thoughts and emotions and even to induce them is really seductive.

But it leaves out context, the most crucial ingredient in understanding the mind. fMRI scans are necessarily done in a lab, specifically in a really noisy, claustrophobic machine. Personally, most of the thoughts and feelings I have in life don’t occur in that environment. They occur in real-life situations, with other people, and in situations in which I’m not aware that I’m being scrutinized. Without a doubt, fMRI data teach us a lot about the human brain and some correlates of thoughts and emotions, but it’s not the single explanation for all that goes on in our minds, as many people wish and expect it to be. Satel writes that “mechanism is not meaning. The brain creates the mind through the actions of neurons and circuits, yes, but it cannot reveal its nuanced contents.”

If we want to truly understand the thoughts and feelings that make us human, we have to look beyond the pervasive pretty rainbow pictures of “brain porn” that may at first seem enticing, but in the long run won’t bring the satisfaction we’re looking for.
