The paper mainly concerns itself with a sample of magicians vs another of the general population (with matching age, sex, etc). The second part compares magicians with artists, actors, comedians, poets, musicians, and a general population. Personally the most suspicious part about this is the O-LIFE questionnaire; it tests for things like "unusual experiences", "cognitive disorganisation", "impulsive nonconformity", "Introvertive anhedonia", and a bunch of other things that are reminiscent of all the non-replicable personality research from a decade ago. O-LIFE was developed in 1995, well before replication crisis questions started popping up, so who knows.
