This is how I read it. I think the problem is that the percentage of men in the study who neither own guns nor feel inadequate is smaller than expected. They are obviously there—I’m married to one. But perhaps a lot of men who don’t want to own guns still feel insecure about their genitals, and that’s what we’re seeing. Men who are more likely to own guns are probably just better at self delusion. But obviously there are still plenty of men on the other side—those who own guns and still feel inadequate.
I’m too lazy to get into the weeds on this study. I’m not a scientist after all. But I would be very surprised if it’s actually 1:1 guns make you feel better about your penis.
