Further evidence for positive correlations of intelligence and suicide rate across Italian regions: Responsum to Felice (2010)
Voracek (2009, Psychol. Rep.) found regional IQ estimates and suicide rates to be positively correlated across 13 (out of 20) Italian regions. Felice (2010, Psychol. Rep.) criticized this group-level (ecologic) finding from geographic analysis on various grounds. These arguments are addressed and rebutted here. Further, replication tests with two new, independent data sources for regional Italian IQ, now including either 19 or all the 20 regions of Italy, show that these are similarly positively correlated with suicide rates. Finally, the group-level finding of Voracek (2009) and its two successful replications are now directly confirmed by recent individual-level (register-based) evidence for higher educational attainment (an IQ proxy) in Italian suicide victims, compared to deaths from all other causes.
