Report: Too many men breeds violence

RIYADH, Saudi Arabia, July 20 (UPI) -- U.S. intelligence officials are showing heightened interest in scientific theories that male-heavy populations are more prone to terrorism, ABC News reported.

Noting that in the terror attacks of Sept. 11, 2001, six of the aircraft hijackers came from the small Saudi town of Abha, where males far outnumber females, political scientists Valerie Hudson and Andrea den Boer predict the world is becoming more dangerous because of gender distortion.

In their book, "Bare Branches: Security Implications of Asia's Surplus Male Population," the pair discuss the alarming global security implications of a surplus of males in the world's most populated countries such as India and China.

For security experts, the implications of the study are immense. At a recent security conference, Hudson says CIA analysts approached the authors after they presented their paper on gender ratio and global violence.

"They asked about our work and wanted our opinions about U.S. policy options for governments affected by abnormal sex ratios," says Hudson, a professor of political science at Brigham Young University.
