A study by researchers at Saint Louis University indicates what many of us had already assumed – that the events of September 11th, 2001, changed the way Americans look at the world. The University’s Professor Frederic Wolinsky says we now feel less in control of our own destinies. Wolinsky says this is the first comprehensive “before and after” study conducted on the effect of the terrorist attacks. He says prior to the attacks, his team had already begun an investigation of how patients with illnesses felt about their lives. The tragic events allowed the team to conduct “before and after” research.
