Identifies which nodes in a network have the most influence, reach, or control. Use when asked 'who are the key players', 'who should we target', 'where is the bottleneck', 'who connects everyone', 'who would we lose most if they left', or when mapping influence in an organisation, market, or social network.
Models how things spread through networks — ideas, behaviors, viruses, product adoption, financial contagion, cascading failures. Use when asked 'why did this go viral', 'why isn't this spreading', 'how do we accelerate adoption', 'what's the tipping point', 'could this cascade', or when modeling any spread or diffusion process through a connected system.
Anchors estimates in historical base rates before adjusting for specific factors. Use when asked 'what's the base rate', 'am I being too optimistic', 'outside view', 'reference class', 'how often does this actually happen', or 'historical frequency'.
Applies disciplined observation to a situation — suspending interpretation to see what's actually there before deciding what it means. Triggers: 'observe this carefully', 'structured observation', 'what do you actually see', 'suspend interpretation', 'look more carefully'.
Identifies all reinforcing (+) and balancing (−) feedback loops in a system. Use when asked to 'map the feedback loops', 'why does this keep happening', 'unintended consequences', or 'system keeps oscillating'.
Identifies what recurring cycle a situation is an instance of and where in that cycle you currently are. Use when asked 'what cycle is this', 'where are we in the cycle', 'have we seen this before', 'detect the pattern', 'hype cycle', or 'where in the curve'.
