"World Trade Center Building 7 is the 47-story skyscraper that was not hit by any planes during the September 11th attacks, but still totally collapsed later the same day. This collapse was not investigated by the 9/11 Commission. Are you aware of this skyscraper’s collapse, and if so do you believe that the Commission should have also investigated it ? Or do you believe that the Commission was right to only investigate the collapse of the buildings which were directly hit by airplanes ?"

• Responses : 43% Not Aware / 38% Aware - should have investigated it / 14% Aware - right not to investigate it / 5% Not Sure

"Some people say that so many unanswered questions about 9/11 remain that Congress or an International Tribunal should re-investigate the attacks, including whether any US government officials consciously allowed or helped facilitate their success. Other people say the 9/11 attacks were thoroughly investigated and that any speculation about US government involvement is nonsense. Who are you more likely to agree with ?"

• Responses : 47% Attacks were thoroughly investigated / 45% Reinvestigate the attacks / 8% Not Sure

The third major Zogby poll regarding 9/11 was conducted in August of 2007. It was a telephone interview with a target of 1,000 interviews with randomly-selected adults from across the United States, consisting of 71 questions, with a 3.1 percent margin of error.[3]

The first 9/11 poll carried out by the New York Times and CBS News was conducted in May 2002. The same questions were asked again in October 2006. This poll was conducted by telephone on 983 randomly-selected citizens of the United States, with a 4% margin of error.[5] One of the questions was the following :

"When it comes to what they knew prior to September 11th, 2001, about possible terrorist attacks against the United States, do you think members of the Bush Administration are telling the truth, are mostly telling the truth but hiding something, or are they mostly lying ?"

• May 2002 responses : 65% said they are hiding something, 8% said they are mostly lying, 21% said telling the truth, 6% not sure.
• October 2006 responses : 53% said they are hiding something, 28% said they are mostly lying, 16% said telling the truth, 3% not sure.

A poll from July 2006, sponsored by Scripps Howard and conducted by Ohio University, surveyed 1,010 randomly-selected citizens of the United States, with a margin of error of 4 percent.[7] It made some statements relating to some of the 9/11 conspiracy theories and asked respondents to say whether they thought that the statements were likely to be true.

"Federal officials either participated in the attacks on the World Trade Center and the Pentagon or took no action to stop them".

• 59% "not likely"
• 20% "somewhat likely"
• 16% "very likely"[8]

"The collapse of the twin towers in New York was aided by explosives secretly planted in the two buildings".

• 77% "unlikely"
• 10% "somewhat likely"
• 6% "very likely"[9]

"The Pentagon was struck by a military cruise missile in 2001 rather than by an airliner captured by terrorists".

• 80% "not likely"
• 6% "somewhat likely"
• 6% "very likely"[10]

The organization in November 2007 surveying 811 Americans about their beliefs in several conspiracy theories asked this question[11]

How about that some people in the federal government had specific warnings of the 9/11 attacks in New York and Washington, but chose to ignore those warnings. Is this very likely, somewhat likely or unlikely ?

• 32% "Very Likely"
• 30% "Somewhat Likely
• 30% "Unlikely"
• 8% "Don’t Know/Other"
