Report Potter's Nod - What is it? in Aesthetic Approaches and Philosophy Posted April 1, 2019 I have noticed a couple professors that have the nod. In their cases it's definitely a nod slight movement side to side but pretty dramatic movement of the head up and down. Neither of them realized that they did it when I asked about it. I sometimes move my mouth when I'm feeding the babies. It seems to be a similar relationship where an action invokes a subconscious behavior. Most of the nodders I know don't realize that they are doing it. I am as of yet not a nodder. Once I realized that for them it was subconscious I began taking note and recording myself throwing and asking whether or not I did it lol.
