Self-determination theory
A theory that people have three basic psychological needs (autonomy, competence and relatedness) and that motivation ranges from controlled (pressure, reward, guilt) to autonomous (valued or enjoyed for itself), with autonomous motivation producing better persistence, performance and wellbeing.
What drives it
It explains why the same task drains one person and energises another, and why carrots and sticks often backfire. For identification, it tells you which need is being frustrated when someone goes flat or rebellious.
How it shows
Work
Autonomy frustration: 'Just tell me what you want then', compliance without ownership, energy returning when given a say. Competence frustration: avoiding stretch assignments, overpreparing. Relatedness frustration: high performer who quietly disengages after being left out of the inner circle. Controlled motivation sounds like 'I have to', 'they expect', 'I'd feel bad if I didn't'.
Relationships
A partner who is cared for but controlled ('I'm only saying this for your own good') becomes either compliant and resentful or oppositional. Children of controlling parents often perform well and feel nothing about it.
Self
Notice the grammar in your head: 'I have to' and 'I should' mark introjected or external regulation; 'I want to' or 'this matters to me' mark autonomous regulation. The tell is whether the activity collapses when nobody is watching or checking.
What tells it apart
Maslow's hierarchy of needs: SDT needs run in parallel and trade off in real time; you will see someone give up pay for autonomy, which a ladder model does not predict.
Intrinsic and extrinsic motivation: Intrinsic versus extrinsic is the two-ended version; SDT adds the middle ground where an externally set goal has been genuinely adopted, so someone doing a dull task willingly because they endorse its purpose counts as autonomous.
Psychological reactance: Reactance is a burst of pushback against a specific restriction and fades when the threat goes; chronic autonomy frustration shows as long-term flatness or compliance without ownership.
A test
Change one thing at a time (give choice, give a winnable stretch, include them) and see which change brings the energy back.
Questions to carry
- When someone came back to life at work, what had changed: more choice, a winnable stretch, or being included?
- In the task that drains me most, which is missing: my say in it, my skill, or the people?
How strong the research is
moderate. A large cross-cultural literature supports the three needs and the autonomous versus controlled distinction; much of it is correlational and self-report, and intervention effects are smaller than the theory's reach suggests.
