In 1999, University of California psychologist Nicholas Christenfeld and his colleagues reviewed thousands of state death certificates and found that males with negative initials (D.I.E., P.I.G., R.A.T.) had died 2.80 years younger than matched controls. Males with positive initials (H.U.G., W.I.N., V.I.P.) had lived 4.48 years longer.

Why? “At present, the best available explanation for these findings is that they are due to the symbolic power of one’s name. It seems unlikely that a person with initials like A.S.S. or J.O.Y. could fail to notice the negative or positive connotations.” Suicide and accidents showed the strongest differences between the positive and negative groups.

But a later study by Pomona College economist Gary Smith found no such pattern.
