TV/VG/IC is the escape mechanism, and the escape artist, whether he/she stays in the 4 walls of his/her room or occasionally ventures out, lives in the confines of his/her escape world.
Perhaps we can consider aspects of "Hikikomori" as a uniquely Japanese manifestation of this condition, mingling itself in fascinating fashion with Japanese cultural nuances.
Thought experiments: Would Boo Radley have been a hikikomori if he lived in Kyoto rather than Maycomb, Alabama?
What are the differences and similarities between: (1) a hikikomori living in Kyoto, (2) a person living in inner city Detroit, MI, living from welfare check to welfare check and watching TV 16 hours a day, and (3) a college dropout living with his parents in suburbia and watching TV 16 hours a day?
In what ways is a hikikomori who programs different than the TV/VG/IC escape artist?
Would Boo Radley have saved Jem and Scout Finch in "To Kill a Mockingbird" if he had been playing video games 16 hours a day?
Find two studies whose authors claim watching television: develops a sense of wonder, encourages critical thought, benefits interpersonal relationship skills, solidifies familial bonds, promotes physical well-being, reduces the objectivization of persons, cures depression, increases patience and self-control, reduces sense of entitlement, grows positive self-worth, and decreases worry, sense of isolation, and self-pity. Next, find studies coming to the opposite conclusion.
