The self-fulfilling prophecy in sport occurs when an expectation about an athlete changes behaviour toward that athlete, causing the athlete to respond in a way that confirms the original expectation. It can produce positive or negative effects on confidence, motivation and performance.
How the process works
The prophecy operates as a cycle rather than through the expectation alone:
| Stage | Sporting example |
|---|---|
| 1. An expectation is formed | A coach believes one athlete has greater potential than another. |
| 2. Behaviour changes | The coach gives the favoured athlete more encouragement, detailed instruction, challenging practice and opportunities to compete. |
| 3. The athlete responds | Greater attention increases the athlete's self-confidence, effort, persistence and skill development. The other athlete may become less motivated. |
| 4. The expectation is confirmed | The favoured athlete performs better, appearing to prove that the coach's original judgment was correct. |
This links to mental toughness because expectations can influence an athlete's confidence, motivation and ability to persist under pressure. A positive expectation may strengthen commitment and perceived control, while a negative expectation may reduce effort and increase fear of failure.
For example, a tennis coach labels a player as mentally strong and repeatedly selects them for deciding matches. The player gains experience in high-pressure situations, becomes more confident and performs increasingly well under pressure. The coach's expectation therefore contributes to the behaviour that confirms it.
A common misconception is that a self-fulfilling prophecy means simply “believing something makes it happen.” The effect is not automatic or mystical: the expectation must influence interactions, opportunities, feedback or the athlete's own behaviour.
Exam technique
For an IB SEHS question asking you to explain the self-fulfilling prophecy, identify the expectation, show how it changes behaviour, and connect the athlete's response to the confirmation of that expectation. Use a specific sporting example and explain the full causal chain; merely defining positive thinking will not earn full marks.
