The creator of the 2channel and current owner of 4chan Hiroyuki Nishimura explains it:
>people can only truly discuss something when they don’t know each other.
>If there is a user ID attached to a user, a discussion tends to become a criticizing game. On the other hand, under the anonymous system, even though your opinion/information is criticized, you don’t know with whom to be upset. Also with a user ID, those who participate in the site for a long time tend to have authority, and it becomes difficult for a user to disagree with them.
>Under a perfectly anonymous system, you can say, “it’s boring,” if it is actually boring. All information is treated equally; only an accurate argument will work
