Editorial spotlight: ↑ the joint agency threshold — where 'we' becomes possible

Concepts

• Tomasello's agency (self-regulating organism) (importance 5): The capacity of an organism to control its own actions in pursuit of goals. The axis for cognitive evolution — not intelligence, but control.. Source: (from training memory of book).
• feedback control agency (importance 5): Most basic form — organism adjusts behavior based on environmental feedback. Ancient animals, simple loops.. Source: (from training memory of book).
• goal-directed agency (importance 5): Second tier — organism represents goals internally and pursues them flexibly. Great apes, tool use, mental simulation.. Source: (from training memory of book).
• intentional agency (importance 5): Third tier — organism makes rational decisions among multiple goals based on reasons. Early humans, normative thinking.. Source: (from training memory of book).
• joint agency (Tomasello's 'we') (importance 5): Fourth tier — organisms coordinate as a plural subject with shared goals and joint commitments. Modern humans, collective intentionality.. Source: (from training memory of book).
• collective agency (importance 5): Fifth tier — cultural groups develop institutional norms and roles that persist beyond individuals. Human culture, institutions.. Source: (from training memory of book).
• shared intentionality (importance 5): The capacity to form joint goals and attend to things together. Humans' unique collaborative foundation.. Source: (from training memory of book).
• Tomasello's collective intentionality (importance 5): Joint attention + joint goals + joint commitments. The cognitive foundation of human culture.. Source: (from training memory of book).
• hierarchical goal structures (importance 4): Goals nested within goals — subgoals serve superordinate goals. Apes plan tool sequences; humans plan life trajectories.. Source: (from training memory of book).
• rational decision-making (importance 4): Choosing among alternative goals based on reasons (expected value, moral considerations). Uniquely human.. Source: (from training memory of book).
• normative self-governance (importance 4): Evaluating one's own reasons and actions against standards. Humans ask 'should I?' not just 'do I want to?'. Source: (from training memory of book).
• second-personal engagement (importance 4): Direct you-me interaction where each recognizes the other as agent. Foundation for joint agency.. Source: (from training memory of book).
• joint commitment (importance 4): Mutual obligation to pursue a shared goal. Creates 'we' as an agent distinct from each 'I'.. Source: (from training memory of book).
• cooperative communication (Tomasello) (importance 4): Informing and requesting based on shared background and mutual helpfulness. Precursor to language.. Source: (from training memory of book).

Claims

• agency-first vs intelligence-first (importance 5): Tomasello's thesis: cognitive evolution is about control (agency), not processing power (intelligence). The real axis.. Source: (from training memory of book).
• Tomasello's cooperation hypothesis (importance 4): Human cognition evolved for collaboration, not just competition. Joint agency drove our unique abilities.. Source: (from training memory of book).
• agency precedes language (importance 4): Joint intentionality emerges before conventional language. Language builds on shared intentionality, not vice versa.. Source: (from training memory of book).
• obligate collaborative foraging (importance 3): Early humans needed to cooperate to survive. This selection pressure drove joint intentionality.. Source: (from training memory of book).
• agency vs mere mindreading (importance 3): Understanding others' minds is necessary but not sufficient. Joint agency requires shared goals, not just mental attribution.. Source: (from training memory of book).
• human self-domestication hypothesis (importance 2): Humans show domestication syndrome (reduced aggression, neoteny). May result from selecting cooperative partners.. Source: (from training memory of book).

Empirical results
