It doesn’t take much genetics experience to understand that recessive genes are more likely to be passed along and expressed by people falling from the same family tree. But that won’t stop John Stossell from making the following remarks:

“I’d always thought marrying a blood relative as close as a cousin was immoral, and certainly risky if you plan to have kids. Conventional wisdom says only primitive people who live in isolated places marry cousins. It leads to stupid children. But that’s a myth. It’s the sort of myth that leads to stupid laws. Half the states in America have banned cousin marriage, but there’s no good reason for it. You can marry your cousin and have perfectly intelligent kids.” — Townhall.com contributor and ABC News commentator John Stossel, confronting one of the most divisive cultural issues of our time
So whether you want to make a scientific argument, or a values argument, Stossel is wrong on this one.
