At least 25%
but this is not a flaw in my plan it's a flaw in society, you either have to declare those 25% incompetent and not let them vote or run their own affairs, or just accept that they are adults with the same rights as the rest of us.

Personally I'd have a sliding scare of citizenship based on tests both of knowledge and intelligence. I'd also have compulsory contraception for all from puberty, only reversible after you have proved you can support and care for a child.
