I had already been working on an article exploring reasons people in the Western world are leaving the Christian church in significant numbers when I learned about the fascinating case of “split-brain” surgeries – something that totally blew my mind (no pun intended).
In the 1960s Roger Sperry, Joseph Bogen and colleagues performed an experimental surgery, officially known as corpus callosotomy, on multiple patients who suffered from epileptic seizures. The procedure involved severing the corpus callosum which connects the left and right hemispheres of the brain.
Though the procedure is no longer performed today it turned out to be highly successful and, for the most part, patients were able to go on to live normal, healthy lives. But it wasn’t long, however, before split-brain patients noticed some peculiar and fascinating side effects.
One patient reported reaching into the closet with the right hand to pick out an outfit, only to have the left hand pick something different and refuse to put it back. A man found himself going to embrace his wife with one arm while his other arm simultaneously pushed her away.
On a more dangerous level, a female patient relayed that when she was driving her left hand would snatch the steering wheel from the right. She also reported her left hand: unfolding sheets her other hand had folded, closing doors the other had opened, and snatching money back that her right hand offered to a cashier.
In short, because each side of the body is controlled by the two different halves of the brain (the left side by the right hemisphere, the right side by the left hemisphere) these side effects seemed to indicate that the two hemispheres of the brain have two completely separate, and sometimes competing, wills.
So what does this have to do with people leaving the church?
One half of the person’s brain had faith and the other half was an atheist.
Here’s where things get even more interesting. Split-brain patients naturally became the subjects of further brain experiments. Able to selectively control input to each hemisphere, neuroscientists used the opportunity to direct various questions (via input to the left versus right eye or ear, for example) in order to determine how each half separately handles various functions or attitudes.
In one experiment, V.S. Ramachandran reportedly asked a patient, “Do you believe in God?” The response from one hemisphere was “Yes” and the other hemisphere was “No.”
In other words, one half of the person’s brain had faith and the other half was an atheist.
What does this mean? Is our faith biologically controlled and entirely dependent upon whether we are “left brained” or “right brained?”
My answer is that it’s a bit more complicated than that. But what I hope to demonstrate throughout the rest of this article is what I have come to believe is the root cause of the mass exodus from the church in Western society – we are all operating out of a “split-brain” mode, largely dominated by left-brained only thinking.
Such thinking has infiltrated the Christian church itself for years, creating an unsustainable belief system largely removed from the type of lived-out faith that Christ intended. The consequences are that the jig is up, the dominoes are now starting to fall and people no longer see the God who has been presented as something that is real. Continue reading
