When your brain's ability to predict what comes next goes awry, you may start to see or hear things that aren't there. A new study from Yale University suggests that making music in a group can help retrain these faulty prediction systems, reducing paranoia and reconnecting people with reality.
The Research
Published in the journal Psychosis on April 9, 2026, the study was led by Philip Corlett, PhD, an associate professor of psychiatry at Yale School of Medicine. The team recruited 20 participants aged 18 to 65 with schizophrenia or distressing auditory hallucinations. Over six weeks, these individuals took part in weekly two-hour group songwriting sessions guided by music facilitator Adam Christoferson.
Before and after the program, participants completed psychometric questionnaires measuring paranoia and hallucinations. The results were striking: those with less severe symptoms reported a measurable drop in paranoia. In addition, linguistic analysis showed a shift from using first-person pronouns like “I” and “me” to plural pronouns like “we” and “us,” indicating a return to social connection. “People with psychosis often use first-person pronouns due to distress and isolation,” Corlett notes. The music therapy had no negative side effects—unlike antipsychotic drugs, which can cause lethargy and brain fog.
Corlett's theory is rooted in predictive coding: our brains constantly generate expectations based on past experiences. In psychosis, these predictions become too strong, leading to hallucinations. Music, which relies on rhythmic and melodic expectations, provides a safe way to challenge those predictions. “Like a roller coaster, music is a safe way of having our expectations violated,” Corlett says.
Why It Matters
This study offers a non-pharmacological way to improve quality of life for people with psychosis. While it doesn't cure hallucinations, it reduces paranoia and fosters social bonds. The findings also highlight the brain's plasticity—consistent music-making may permanently rewire dysfunctional prediction circuits. For anyone interested in cognitive health, this research underscores how structured sensory experiences can shape brain function.
What You Can Do
You don't need to have psychosis to benefit from music's predictive power. Try learning a new instrument, singing in a choir, or even tapping along to a rhythm. Engaging with music challenges your brain to make and update predictions, which can improve your cognitive flexibility. For a more structured approach, explore brain training exercises that involve pattern recognition and timing.
