"Bystanders are actually the answer to the problem," she said. "If we could train bystanders to report, or to train them to act as a group to intervene, hazing might be reduced."
A 2008 study showed that 55 percent of college students in clubs, sports or other organizations experienced hazing.
"I believe that hazing is becoming more prevalent, more violent, and more sexualized," Lipkins said. "One reason is that with each hazing the perpetrators want to leave their own mark so they usually increase the violence, the humiliation, the sexuality, etc."
But experts have differing opinions on whether hazing is getting better or worse.
"We have seen lots of organizations ban it and in most states (44) it is against the law," Power said. "I do see it becoming less violent when it does occur."
By walking out of the situation, Martin helped shed light on bullying and hazing in the NFL by sparking a conversation, Lebowitz said.
For example, an unscientific survey of NFL players by ESPN conducted last week showed that most of the 72 players surveyed -- 57 percent -- would not want Incognito as a teammate. And 43 percent said they had been victims of hazing while playing in the NFL.
