This study tested whether polygenic risk scores for schizophrenia and bipolar disorder would predict creativity. The authors found that higher scores were associated with artistic society membership or creative profession in both Icelandic and replication cohorts. They concluded that this could not be accounted for by increased relatedness between creative individuals and those with psychoses, indicating that creativity and psychosis share genetic roots.
