Dyslexia is real. There’s no denying that. However, there is a small group of literacy professors who think dyslexia is a myth. The article below is from way back in 2019. At the time, I released audio from a prominent literacy professor making outrageous claims about dyslexia and a newly passed dyslexia law in Tennessee.
Richard Allington is a huge name in literacy. Think about how many teachers and professors he trained to think that dyslexia wasn’t real. Around the same time I went to a national literacy conference where I heard professors talk about how dyslexia was a myth.
It. Was. Wild.
I was taught in my PhD program that there were people like this, but it was mind blowing to see it in happening in front of my eyes.
It’s people like that who have kept the field of literacy from moving forward. We can have debates about specific teaching practices, but you can’t have collaborate conversations with someone who does not believe in learning disabilities.
Dyslexia is real, and we need to identify students and provide intensive intervention.
Dyslexia exists. What is inflated is the scale.
A large share of children given the label are not dyslexic. They shut down when early instruction confuses them, then get classified and routed into assessments, therapy, and special education. That pipeline is a multi-million-dollar business, and it has a strong incentive to keep the numbers high.
The condition is real. The industry built around over-identifying it is the problem.
In my post from December 2019 (Zack Barnes and Dyslexia), I argued that the real issue is not whether dyslexia exists but how wrong teaching practices create confusion that masquerades as disability. Children are taught extraneous sounds for letters (b → buh, m → muh) and then blamed when they fail to blend. Logical children disengage when reading is made illogical, and many are wrongly labeled “dyslexic.”
Key points from my blog:
Wrong teaching practices: Teaching distorted sounds leads to confusion, not disability.
Dolch word memorization: Rote learning of high-frequency words builds fluency and confidence, yet is neglected.
Multiple sounds per letter: Children must be told early that letters often represent more than one sound.
Mislabeling bright children: Many intelligent, logical children disengage when instruction is illogical, then get swept into the dyslexia industry.
The tragedy is that these children are not dyslexic in the neurological sense. They are victims of poor instruction. The industry profits from assessments and therapies, while the root cause—wrong teaching—is ignored.
Barnes is right: dyslexia is real. But the numbers are inflated because confusion is mislabeled as disability. If we want to move literacy forward, we must stop blaming children and start fixing instruction.
