> 1% of people stutter Honestly I've always had huge doubts about this 1%. I wonder what the methodology for deducing this was. If these figures were self-reported, then I'd speculate that it's probably inflated a lot by counting in otherwise fluent people who have occasional stumbles in their speech - which doesn't necessarily amount to actual stuttering. I know a handful of people like this, but the difference is if they focus and simply practice, they can actually get themselves to be fluent, because there's nothing neurological that impedes the flow of their speech. Whereas "trying" and "focusing" just aren't things that work for us. Remember that even fluent people sometimes stammer. That's why suggestions like "just slow down" and "think about what you want to say" are commonplace - because these actually work for people that are momentarily tongue-tied but otherwise don't actually have anything affecting their fluency. People don't intuitively grasp how ridiculously huge 1 in 100 really is. Also factoring in the ~4:1 gender ratio, what this would mean is something closer to 1 in 50 males has a stutter, which is an even bigger number still. That would mean in every ~2 classrooms, there'd be a boy that stuttered.
