That is a finding of world authority on dyslexia John Stein, professor at Magdalen College. Oxford.
Although dyslexics have poor short-term memory that causes them to get linear strings of letters and words out of sequence, they can make strong long-range connections and are good at seeing unusual associations.
This is particularly useful for some aspects of computing. For example, a key ingredient of clever programming is mastering the power of recursion - functions that can call themselves ad infinitum. Dyslexics are particularly good at perceiving a complete pattern of interaction in a program.
Stein says dyslexia affects 20% of men and 5% of women. Although it stems from a mildly impaired development of certain nerves, he believes the condition enables the clever, long-range connections that we admire in good entrepreneurs, artists and high level computer people.
To ensure successful projects and a balanced IT department it would appear that every IT director should take steps to employ a sprinkle of dyslexics.
