At last, good news for the beta male.

From the wild to Wall Street, as everyone knows, the alpha male runs the show, enjoying power over other males and, as a field biologist might put it, the best access to mating opportunities.

The beta is No. 2 in the wolf pack or the baboon troop, not such a bad position. But conversationally, the term has become an almost derisive label for the nice guy, the good boy all grown up, the husband women look for after the fling with Russell Crowe.

It may now be time to take a step back from alpha worship. Field biologists, the people who gave the culture the alpha/beta trope in the first place, have found there can be a big downside to being No. 1.

Laurence R. Gesquiere, a research associate in the department of ecology and evolutionary biology at Princeton, and colleagues report in the journal Science that in five troops of wild baboons in Kenya studied over nine years, alpha males showed very high stress levels, as high as those of the lowest-ranking males.
