Inspired by the , and past decade, I’ve become obsessed by the implications of neuroscience for the fields of executive coaching, leadership development and experiential learning.
Once you have speech, you don’t
have to wait for natural selection! If you want more strength, you
build a stealth bomber; if you don’t like bacteria, you invent
penicillin; if you want to communicate faster, you invent the Internet.
Once speech evolved, all of human life changed.
And perhaps the most important change is that we’re no longer merely the expression of our genetic heritage; our speech-sodden brains are far more plastic and malleable than our hard-wired genes would ever allow us to be. Advances in genetics in recent decades ultimately suggested that humans lacked free will–our fate was written in our genes. But Wolfe sees things differently–more from his Chronicle interview:
I’m willing to say OK, we may
have no free will, but speech creates so many variables that it doesn’t
really matter. No machines will ever truly fully figure the brain out,
because the brain’s performance is constantly altered or else
constrained by this inanimate, rogue artifact you can’t control,
namely, speech. Laws you obey, scientific findings you assume to be
correct, creeds you believe in, existing plans you go by, history as
you understand it - these artifacts, once accepted, will affect your
thoughts and behavior and use you more than you use them. Culture is just too big a variable to explain away with genetics…
And just as Lieberman, et al’s research on provides a scientific explanation for a practice that I’ve used in my own work countless times, Wolfe’s theories and the neuroscience on which they’re based suggest that many of the practices we employ in coaching, leadership development and experiential education are effective because they’re consistent with–and take advantage of–the way our brains function. (And at the same time, neuroscience also has the potential to tell us which practices and techniques are ineffective and need to be updated or scrapped.)
As noted above, I’m mindful of the limits of neuroscience, and I’d hate to see the genetic determinism of recent years replaced by a "neuro-determinism" that simply substituted brain scans for gene maps. But we’re clearly at a point where humanistic professionals–executive coaches, OD consultants, experiential educators–need to incorporate neuroscience into their practices.
* Wolfe actually suggests that we rename ourselves Homo loquax–"Talkative man"–a proposal that may have been inspired by Walter Miller’s , in which Miller called us Homo loquax nonnumquam sapiens–"Talkative, and sometimes wise, man."
