Here’s the moment of truth: Anybody in this audience have dyslexia? Show of hands. Thank you.
Thank you. Thank you. Some more. Thank you. That’s almost a fair assessment.
We’ve got about 20% of the general population has dyslexia. That’s 1 in 5 people. And I think that dyslexia is most commonly understood as this reading issue, you know, we have a tendency of flipping our b’s and d’s and our q’s and g’s, and that’s, you know, I think that’s a fair assessment, at least in the symptomatic department.
But I want to take this opportunity to speak a little bit more in depth about the neuroscience of dyslexia.
So, we have this outer layer of our brain called the cortex. And we all know that we have — or maybe we don’t know – but we have these little things called minicolumns, okay? And these minicolumns serve as the telephone poles, if you will.
What strings together on these minicolumns are axons. Okay? Now, people with autism, for example, have axons that are extremely closely located in proximity to each other, and as a result, their axon lengths are very, very finite and short, and as a result they are able to do these incredibly detailed, highly specific patterns and behaviors and skills, right?
Well, dyslexics are on the other side of that spectrum; we have our minicolumns that are spaced very, very far apart. As a result, our axon lengths are significantly longer. And this actually lends to some significant cognitive advantages.
We have an ability to look at a situation and identify seemingly disparate pieces of information and blend those into a narrative, or a tapestry, that makes sense to us that most people can’t see.
So this translates into an exceptional level of success in four major vocational paths. That’s entrepreneurship, engineering, architecture and the arts. I just want you to please remember that, as it comes up later in this discussion.
Dyslexia comes with a cost though, okay? We have an incredibly difficult time doing what’s called phonetic decoding. Okay, that’s the most complex word I’m going to use, and I hope you’re impressed by it.
Phonetic decoding is essentially our ability to identify these squiggly lines, translate those lines into a sound in our mind and then string those sounds together to compose a word. For dyslexics, that takes five time more energy than a normal brain.
So, to give you a little bit of a historical context on dyslexia, I’ll go back and start off with the first nine-tenths of human existence. Societies were largely based on apprentice models, right? From hunter and gatherers down to the trades in more recent times, people learned by observing and then doing kinesthetic learning.
Now, this happens to be the wheelhouse for dyslexics; this is our prime opportunity to learn. Then there was this little twist in history, okay? It was called the Industrial Revolution.
And what happened during the Industrial Revolution is the society said, “Okay, we’ve got this new form of economy. What we need to do is educate the masses to become effective worker bees in these factories.” Now, this dovetailed historically with the importation of the printing press from Europe.
And so everyone was incredibly excited that they had this newfound technology that would enable us to embed knowledge into a format that could then be scaled and distributed on a national level.
