We produced zero good priori forecasts in the differences when considering unmarried and you can partnered men’s face elegance critiques. Finally, to be sure the capability to examine brand new BO and face product reviews off unmarried and you may partnered guys, people ranked the newest stimuli out of three single and you can around three hitched not familiar guys.
