Catalyst in the Chain of Causality?

Taking the analogy from the discussion of Catalyst and Reverse-Catalyst in chemical reactions to Psychology, we could suppose there exists a kind of personality which help catalysis certain effect in the chain of causality and other personality which help to reduce certain effect in the chain of causality. Applying the analogy, tension is generated and absorbed by these personalities to increase/decrease the rate of certain type of interactions between other personalities. That actually is a Buddhist idea.
