So people used to think there was only one standard-issue type of brain, and that everyone's brain operated in the same way and could learn the same things equally well, and a single optimal technique could be developed and taught once to everyone. The Taylorist dream, among others. But left handed people kept stubbornly existing, despite the beatings. And then education discovered that dyslexia and dyspraxia are things. And the not-well-understood category of "non-neurotypical" people currently classified into conditions like autism, Aspergers, ADHD etc. Eventually we're going to learn to fit the technique to the human rather than the other way round. People over processes, and all that.
This may explain why people have strong-but-wildly-different opinions about which programming languages are "intuitive". Maybe some are just ""left-handed"", in a very non-literal sense.
(I'm a left hander from just slightly after the "beating children for being left-handed" era, but I expect there's someone in the audience who remembers it)
