Changing attitudes towards religion in the U.S.: 2006 v. 2011

"PALS is a six-year national study tracking religion, morality, politics and other social issues in the U.S. The study included a scientifically gathered random sample of approximately 1,300 adult Americans in 2006 and 2012, interviewing the exact same people in both years.

When asked about mutual respect for all religions, one-third of PALS participants in 2006 said they respected all religions equally. By 2012, 58 percent said they did."

2006: 5 years after 9-11
2012: 11 years after 9-11

Are these indicators of the effect of the media on religion?
