Goaliath is built on robust behavioral science. This page summarizes the key theories that inform each feature so you know not only how to use the app, but why it works.
SDT shows that sustained motivation thrives when three needs are met: autonomy (you choose), competence (you can), and relatedness (you belong). We foster:
Behavior = Capability × Opportunity × Motivation. Goaliath strengthens all three: capability (skills & knowledge from Lessons/Mental Models), opportunity (calendar scheduling and reminders), and motivation (analytics, nudges, and meaning from your North Star).
Specific, challenging goals with feedback outperform vague intentions. The Goal Planner guides you to clarify outcomes, timeframes, and objective checkpoints, then Today’s Actions provides daily feedback.
The “If situation X, then I will do Y” plan dramatically increases the likelihood of follow-through. Our Implementation Intentions tool helps you encode if–then plans directly into your daily script and calendar.
Contrast your desired future with present obstacles to focus effort on what matters. Mental Contrasting and related tools help surface obstacles early and pair them with concrete responses.
Repetition in stable contexts builds automaticity. Use habit stacking, cues, and small wins to stabilize routines. The Habits, Calendar, and daily email snapshot create consistent prompts and rewards.
Long-term retention requires scheduled reviews. Our Ultra-Learning and Lessons integrate spaced repetition (tested by our FSRS review suite) so critical knowledge resurfaces at optimal times.
