The human being does not wish to make the same mistake twice, it wishes to learn from mistakes, mainly in order to not suffer so much.

This is why processes, instructions, norms are created. They should be drafted by people who have been in that given situation and have learned from it. Instructions and norms tend to turn into structures, which are almos always hierarchical.

They are primarily defence mechanisms to face a situacion that has given negative results in the past. They are not opression mechanisms as such.
