CONCEPT
Performance = Potential − Interference
Gallwey's algebraic expression of the inner game principle — that human performance is determined not by adding more instruction but by reducing the interference of Self 1 with Self 2's natural capacity to learn and execute.
The equation P = p − i compresses Gallwey's forty-year career into three variables. P (Performance) is the observable outcome — the quality of the tennis stroke, the fluency of the musical phrase, the elegance of the code, the clarity of the strategic decision. p (potential) is the vast, latent capability that every person possesses through years of experience, practice, and embodied learning — what Self 2 knows. i (interference) is the noise generated by Self 1's anxious supervision — the internal dialogue of instruction, evaluation, worry, and self-doubt that occupies attentional bandwidth and disrupts Self 2's fluent execution. The equation's radical claim is that performance improvement does not primarily come from increasing p (adding more knowledge or skill) but from decreasing i (quieting the analytical mind's interference). Most coaching, most training, most professional development focuses on the wrong variable. The highest-leverage intervention is not teaching people more but helping them get out of their own way.
