Psychogeography is an exploration of urban environments that emphasizes playfulness and "drifting". It was defined in 1955 by Guy Debord as:
"The study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behavior of individuals."
"A total dissolution of boundaries between art and life."
"A whole toy box full of playful, inventive strategies for exploring cities...just about anything that takes pedestrians off their predictable paths and jolts them into a new awareness of the urban landscape."
What has emerged here is that although survivorship bias probably does contribute to that to some extent, it is not the main explanation: premodern buildings may on average have been a bit less beautiful than those that have survived, but they still seem to have been ugly far less often than recent buildings are.
The survivorship theory sought to explain the apparent rise of ugliness in terms of a bias in the sample of buildings we are observing. There is another kind of bias theory, which seeks to explain it in terms of a bias in the observer, saying for instance that every generation is disposed to find recent buildings uglier than older ones, and that this is why recent buildings seem so to us. This is a complex and interesting idea, which I am not going to assess on this occasion. Suppose, though, that our eyes are to be trusted. If this is so, strange and eerie truths rise before us: that ugly buildings were once rare, that the ‘uglification of the world’ is real and that it is happening all around us.
