In his controversial book The Demise of Guys: Why Boys Are Struggling And What We Can Do About It, Zimbardo and co-author Nikita Duncan outline why he thinks men are failing in education and personal relationships.

He suggests parents limit or cut off access to computers and video games to get their sons on the right track.

Some highlights from the book:

-Females currently outperform males at every level, from grade school to graduate school. Boys are 30 percent more likely than girls to drop out of high school and college, according to the National Center of Education Statistics.

-In 2011, young men's SAT scores were the worst they had been in 40 years.

-Even Hollywood has caught on: films like Failure to Launch, Knocked Up and Jackass mock the ineptitude of this generation.

-Boys account for 70 percent of D's and F's given at school.

-Research shows guys aren't interested in being husbands, fathers or the head of the household.

-Boys are four to five times more likely than girls to have Attention Deficit Hyperactivity Disorder, according to the National Center for Education Statistics. Two-thirds of students in special education programs are guys.

-The average boy spends 13 hours a week playing video games. The average girl spends 5. The average young American will spend 10,000 hours playing video games by age 21. That's twice the time it takes to earn a bachelor's degree.

-The average high school boy spends two hours watching porn every week. Men can't escape porn: 13,500 full-length commercial porn films were released in 2011, compared with 600 Hollywood films.

-Researchers claim that internet pornography is hurting young boys' ability to form meaningful romantic relationships because they objectify their partner.
