I could google but lets have a discussion instead. What is psycho-geography?
Well, I'm glad that you asked because... hmm not really glad, I'm clearly not fully grasping the thing myself ;-), hence the desire to read a certain book on it, which I didn't name because it is in French.
The quote that come the most often when you google this domain is one by the intellectual Guy Debor : "the study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behavior of individuals."
Oversimplifying it, because I'm NOT the man to talk to to fully understand the thing, it would be the study of how some urban environments affect our feelings. And as I said, while at first I dismissed this as 'oh god not interested' and 'a little too masturbatory', the concept crept with me and I'm feeling more and more interested in it and other social / urban studies.
