Watch out for Swedish men whose names end with -y.
Because Erik Segerborg and Mikael Söderström of the Stockholm School of Economics have shown that “y-name syndrome” — a widely accepted idea in Sweden that links men whose names end with -y (e.g. Ronny, Conny, Benny) to crime and poverty — has basis in fact.
We find that the y-name syndrome is empirically grounded; men with y-names are more likely to live in municipalities characterized by indicators of low socioeconomic status and are over-represented among criminals.
