Perhaps if women are sitting in a lab judging pictures of smiling and non-smiling guys, this might be true. However, when it comes to meeting someone in the real world, their state is more important than their particular look. A guy that is on a downer isn't going to get girls because, firstly, he is going to be held back by negative beliefs and, secondly, this state is going to be transferred to the girl to some extent, then she will be on a downer.
