“Neuro” hype and 21st Century Phrenology

Is the brain the hottest organ in the body? That’s the argument made in a recent Slate story “The End of Neuro-Nonsense” that argues that brain hype reached its peak in 2008 and is now on the decline for a variety of reasons. Quoting from the new book Brainwashed that details the perils of brain-centrism: “Naïve media, slick neuroentrepreneurs, and even an occasional overzealous neuroscientist exaggerate the capacity of scans to reveal the contents of our minds, exalt brain physiology as inherently the most valuable level of explanation for understanding behavior, and rush to apply underdeveloped, if dazzling, science for commercial and forensic use.”

Maybe so.

But I’d argue that we’ve been living a “neurocentric,” to quote the term used in the article for our brain obsession, world for nearly 200 years. We just had a different name for it in the past: phrenology.

Phrenologists posited that the brain was made up of individual organs with specific functions and attributes. The size and shape of these organs, as read on the skull, revealed our character. Many argued that these organs – and thus our personalities – were changeable, improvable. With a little exercise, we could make ourselves better by strengthening positive traits and weakening others. With phrenology, doctors could easily determine not only how but why someone thought, felt, and coped with life in a particular way. It provided comfort and insight into our seemingly unknowable depths, a way to understand behavior and personality with seemingly scientific precision. Who wouldn’t like that?

Like the 19th century, many of us hope today, as the phrenologists did, that mapping the brain will reveal the secrets of our natures. And once known, this information will allow us to manipulate and transform ourselves into something better. We just call it “neuro” this and “neuro” that now, from neuromarketing to neuroeconomics, a transmutation of language strikingly similar to what occurred in the 19th century as phrenological terms (high brow, low brow, shrink, well rounded) passed from the lab to daily conversation. Colorful fMRI images of the brain on TV encourage us to think of almost everything through its effect on the brain, the modern equivalent of the phrenological charts that adorned the walls of pharmacies and general stores and were featured in the pages of magazines and books. Just as in the past, popular neuroscience suggests that the way to make us smarter, happier, and even more beautiful is through concentrated efforts to improve the brain regardless of how little we actually know about how the brain works. It seems to me that popular brain science is the phrenology of the 21st century, and we’re just as ravenous for that knowledge today as they were in the 19th century.

So maybe 2008 marks the most recent crest of a brain obsession with more than two centuries of history behind it that seems bound and determined to rise again.
