Alex O’Connor: #1 Shift That Stops Endless Overthinking (FINALLY Get Unstuck)
"You can flash an instruction to the right hemisphere of the brain, get up and walk over to the window. The patient stands up and they walk over to the window. Then the instructor says, why did you just do that? They make something up and they believe it. It's called confabulation."
O'Connor describes split-brain patient experiments demonstrating that the left hemisphere acts as an interpreter, retroactively rationalizing decisions made by the right hemisphere. He argues this phenomenon likely occurs in healthy brains constantly, suggesting much of our philosophizing and decision-making explanations are post-hoc rationalizations rather than true causes.
