Most cats do seem to target the most reserved or the one who doesn't like cats. My siamese is like that, her human in this house even though she was supposed to be my cat, is my husband, who is very reserved and didn't want to own another cat.
My Maine Coon on the other hand (he always behaves more like a dog, so maybe he's not really cat, but a dog that purrs?) tends to go to the person who has their hands out for petting him and is calling to him.
