Science & Principles
Goaliath uses a clear theory order: Perceptual Control Theory first, then Goal-Setting Theory, then Self-Determination Theory.
How to use this page
Use this as a practical map for why features exist and how to adjust behavior when progress stalls.
Theory order used in product decisions
- Perceptual Control Theory: identify the controlled variable, target level, and current error.
- Goal-Setting Theory: check capability, opportunity, and motivation constraints that block correction.
- Self-Determination Theory: tune autonomy, competence, and relatedness so effort is sustainable.
What good looks like
- Goals have clear references and visible error-correction loops.
- Plans address real capability or opportunity constraints.
- Motivation support preserves agency and avoids pressure framing.
Common issues and fixes
- Progress stalls: inspect control conflict before adding workload.
- High effort, low output: reduce reference level or tighten feedback.
- Motivation swings: increase autonomy and shorten execution cycles.
