"They show that roughly two-thirds of a group of neurotic patients will recover or improve to a marked extent within about two years of the onset of their illness, whether they are treated by means of psychotherapy or not"
About this Quote
The intent is polemical, not merely empirical. Eysenck isn’t just reporting an outcome; he’s challenging psychotherapy’s central narrative of causation. If improvement is common without treatment, then the therapist’s authority becomes statistically fragile. The subtext is an accusation: much of what gets sold as clinical mastery may be a sophisticated form of credit-taking for natural remission. It’s also a warning about the seductive power of anecdotes. A patient gets better after weeks on the couch, and the sequence is mistaken for proof.
Context matters. Postwar Britain and America were awash in psychoanalytic prestige, with “neurosis” serving as a broad, socially legible diagnosis. Eysenck, a behaviorist-minded empiricist, made his name by insisting psychology earn its claims with controls, baselines, and outcome data. His phrasing, “roughly two-thirds,” is doing rhetorical work: modest enough to sound responsible, blunt enough to puncture certainty.
What makes it land is its implication for policy and ethics. If therapy can’t outperform doing nothing, the burden shifts from charisma to evidence, and from comforting stories to measurable benefit.
