Abstract
A central puzzle for the behavioural sciences and for human-facing artificial intelligence is the persistence of within-person variability. The same individual, presented with the same observable input, produces different outcomes on different occasions, and different individuals produce divergent outcomes that no observable covariate fully predicts. The authors argue that this variability belongs in the dynamic latent state of the person, and that human outcomes are controllable in a precise and operational sense through interventions that target the state and its weighting at the moment a decision is being formed.
Key Ideas
- State as a weighting vector: A state is defined as the time-indexed weighting vector over the dimensions that govern how an individual's biology, physiology, and neuropsychology process the next event into a decision and an outcome.
- Causal, not correlational: The relationship between state, decision, and outcome is causal rather than correlational.
- Dynamic timescale: The weighting vector changes dynamically on intra-day (within-day) timescales.
- Attention bottleneck: The conscious channel of reportable outcomes is a narrow attention bottleneck, and the contents of that channel are themselves state-dependent.
Conclusion
Combining these claims, the paper concludes that the outcome of a given event is controllable, conditioned on the state trajectory at the moment of intervention targeting decision formation.
