"A Boolean switching rule (such as) at least one input has a value that can by itself determine the activity of the regulated element" (St. KAUFFMAN, 1991, p.69).
"The OR function is a typical canalizing function" (Ibid). According to KAUFFMAN: "Like low connectivity or biases in the Boolean rules, an abundance of canalizing functions in a network can create an extensive frozen core. Increasing the proportion of canalizing functions used in a network can therefore drive the system toward a phase transition between chaos and order" (Ibid).
Here chaos should possibly be understood as primeval chaos, when a system starts its self organization process. In complex systems, deterministic chaos and order seem to be the two faces of the same global behavior.
