Is it proper to study canine pyschology via dogs kept chained all day long? It helps you understand the chained dog, if that is your goal --- but it doesn't teach you the nature of the dog. I'd like to see studies of teenagers raised neurosis free --- not studies of kids who have been dominated and forced to submit all their lives (which is the essence of American moral conditioning), filling them with repressions that finally reveal themselves during adolescence as antisocial behavior.
