A new study by Szabolcs Keri and colleagues at Semmelweis University in Budapest, Hungary, says that the creativity of a person is influenced by mutations in the gene linked to schizophrenia.
The researchers were examining a gene called neuregulin , which has been linked to the development of the personality disorder in previous studies.
Researchers genotyped 200 adults who answered their ads for creative volunteers. These volunteers were given a series of creative tests, after which researchers found that the people who had two copies of neuregulin 1 mutation tended to be more creative than other volunteers with one or no copy of the mutation.
"My clinical experience is that high-IQ people with psychosis have more intellectual capacity to deal with psychotic experiences. It's not enough to experience those feelings, you have to communicate them," New Scientist quoted Keri as saying.
The details of the study appear in the journal Psychological Science.
