Forget left/right brain tests - they are a nonsense

October 15, 2007

Like many others my RSS feed has been full of the spinning silhouette optical illusion. It has been used as a left/right brain test. You know the theory: left brained people are logical, right brained people are emotional. It is another variation on the absurd but all to common desire for simplistic categorisation models on which I have commented previously. The whole idea is, and always has been an arrant nonsense and you have to be very naive or poorly read to take it seriously (if that offends some people hard luck). I had made a note to myself to put together a post on this, but fortunately Nerophilosophy has done the job for me with an excellent post which I highly commend: The left brain/ right brain myth. A good quote to wet your interest: So the notion that someone is “left-brained” or “right-brained” is absolute nonsense. All complex behaviours and cognitive functions require the integrated actions of multiple brain regions in both hemispheres of the brain

Why oh why, do people want to put other people (and themselves) into neat and tidy boxes; it is so limiting.
