Further Googling of Martin Voracek would have turned up this gem: National intelligence and suicide rate: an ecological study of 85 countries.
Now here's an article that has it all in terms of statistical fallacies. He attempts to argue that intelligence is a causal factor for suicidality using the following methodology: Each country in the world is assigned an IQ and this national IQ is correlated with national reported suicide rates. It's really amazing - he's managed to incorporate the ecological fallacy, reporting bias, selection bias, profound confusion about the definition of IQ (a measure of intelligence relative to a typical individual), unmeasured confounders, terrible measurement methodology and just a generally goofy scientific approach, all in one bogus study! There should be an award for this.
