Maybe the difference in what you two are is that psychological is often internal to one person whereas cultural can be internal to many people. For example, me working on the fear that I have to open up publicly because my house was robbed when I lived overseas and was a semi-celebrity can be my personal psychological journey. The collective "don't share too much about your private life online" could a collective cultural belief stemming from many different experiences that impacted individuals to have such beliefs and fears. I've been thinking a lot about whether to change culture (group) or change psychology (individual) and my latest belief on this is that I want to get better at loving myself and loving others and then train the handful of people who also want to do that, with the idea being that if a few of us start, it may spread to others, this going from the individual to group, maybe psychological to cultural. I don't necessarily like the psych/cultural distinction, as I think both often influence how I'm feeling. Scared to post because I might get robbed again, also scared to post because people may resond with "you shouldn't post things like that online." So I think maybe it's both. However I still like the idea of starting with me and maybe a few others who really really want to get better at it and maybe influence by osmosis.
