Speculative Genetics

I recently hear someone interviewed on the radio claim to have been born with 'journalist DNA'

I don't believe that the individual in question actually thought they had made a remarkable discovery in genetics, and doubt if he or she actually knows what DNA is. I suspect that 'DNA' is a term perceived to be used by clever people, so people who want to be thought clever like to use it too, without bothering to find our what it means.

'DNA' is often misused in that way.
