# Magoroh Maruyama Magoroh Maruyama (1929–2019) was a Japanese-American systems scientist best known for a 1963 paper, "The Second Cybernetics," that split the field's idea of feedback into two families. "First cybernetics" was morphostatic — deviation-counteracting, dominated by the goal-seeking [[Negative_feedback|negative feedback]] that Norbert Wiener's original cybernetics had emphasized. ## Microsim — queued <p class="wt-pending"><strong>Microsim/diagram layer in the draft queue.</strong> Troy is building the interactive station for this concept by hand; the sourced overview below is complete and citable now.</p> ## Overview "Second cybernetics" was morphogenetic — deviation-amplifying, driven by the [[Positive_feedback|positive feedback]] that builds structure, growth, and differentiation rather than damping them out. That distinction gave [[Systems_theory|systems theorists]] a vocabulary for the pattern-forming, self-organizing side of feedback that a purely equilibrium-seeking model could not capture, and it remains a standard reference point for reading a [[Causal_loop_diagram|causal loop diagram]]'s reinforcing loops as something other than a defect to be damped. **On the spine:** [[Positive_feedback]] · [[Negative_feedback]] · [[Systems_theory]] · [[Causal_loop_diagram]]. ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Magoroh_Maruyama) : [Wikitube](https://en.wikitube.io/wiki/Magoroh_Maruyama) ## Previous hub tags Hubs: `Systems`.
