The 9/11 terrorist attacks had a profound impact on the American public, with shock and grief felt across the nation. The attacks were a reminder of the vulnerability of the country and the need for increased security measures. A review of public opinion polls conducted immediately following the attacks showed that Americans were bonded by sadness and patriotism. Many people mourned the loss of loved ones, and the country came together in solidarity to support those affected by the tragedy. However, the attacks also had a lasting impact on mental health, with increased incidence of anxiety disorders, phobias, and alcohol disorders observed in later adult age groups.

In the aftermath of the attacks, there was widespread approval for the government response and military action taken against those responsible. A survey conducted in early 2002 found that 83% of Americans approved of the U.S.-led military action. A Washington Post/ABC News poll released two days after the attacks found that 93% of Americans backed taking military action against those responsible. However, opinions on the war in Iraq, which was seen by some as an extension of the war on terror, were more divided.

The attacks also led to an increased sense of national unity and patriotism. A year after the attacks, a majority of Americans reported feeling patriotic as a result of the attacks. The attacks resulted in immediate, visibly evident increases in expressions of national identification and unity throughout the USA. Trust in government also increased in the aftermath of the attacks, with a jump from 30% to 64% shortly after the attacks. However, as time passed, the sense of unity and trust in government began to fade.

Polls on the Impact of 9/11 in the Years Following

Polls conducted in the years following the 9/11 attacks have shown that there were significant impacts on travel and tourism. According to a recent poll, significant minorities of individuals are less willing to take flights, attend mass events, or travel overseas than they were before 9/11. A study by Chen in 2004 found that the effects of the attacks on the travel and tourism industry were significant, with decreased demand for air travel and increased security measures leading to longer wait times and higher costs. Despite efforts to increase security and restore confidence in air travel, the industry has continued to face challenges, including a recent increase in sightings of unmanned aerial systems near airports. The impact of 9/11 on travel and tourism has been far-reaching and continues to be felt today.

The 9/11 attacks also led to significant changes in security and surveillance measures. Six weeks after the attacks, Congress passed the USA Patriot Act, which expanded the government's ability to conduct surveillance and share intelligence information. While these measures were designed to enhance national security, they also raised concerns about civil liberties and government transparency. Polls have shown that Americans increasingly balk at intrusive government surveillance and express concerns over the erosion of civil liberties. Since 9/11, Americans have generally valued protection from terrorism over civil liberties, but there has also been growing concern about the potential for abuses of power. The impact of 9/11 on security and surveillance measures has been significant and continues to be a topic of debate and concern.

The 9/11 attacks also had an impact on civil liberties and government transparency. Polls have shown that there has been a shift in public opinion since 9/11, with a greater emphasis on national security over civil liberties. However, there have also been concerns about the potential erosion of civil liberties and the need to balance security measures with the protection of individual rights. The USA Patriot Act included provisions that modified authorities relating to privacy and civil liberties oversight. While the Department of Justice has emphasized the need to prevent future terrorist attacks, there is ongoing debate about the balance between security measures and civil liberties. The impact of 9/11 on civil liberties and government transparency has been significant and continues to be a topic of discussion and debate.

Polls on Public Perception of 9/11 Conspiracy Theories

Since the September 11 attacks, there has been a proliferation of conspiracy theories surrounding the events of that day. These theories challenge the mainstream account of the attacks and have gained significant attention and support from the public. The emergence of these theories was almost immediate, with some anti-Bush protesters carrying signs questioning the official narrative as early as late 2001. The reasons behind the emergence of these theories are complex and multifaceted, ranging from political motivations to personal experiences of trauma and disillusionment.

For now we have only one poll about 911 subject. Its for theme - Do you think, that 911 was a inside job? By that poll we see, that people divides by opinion by 50/50.

Despite the popularity of these theories, many experts and officials have worked to debunk them. In a 2008 article, Knight describes the various ways in which conspiracy theories are often discredited, including through the use of scientific evidence and logical reasoning. However, despite these efforts, public skepticism and belief in alternative explanations for the events of 9/11 persist. A 2019 survey found that 33% of Americans believe that the government was involved in the attacks. Research suggests that conspiracy beliefs result from a range of psychological, political, and social factors.

The events of 9/11 continue to hold a powerful hold on the public's collective consciousness, with the twentieth anniversary of the attacks approaching. As such, it is important to understand the reasons behind the persistence of conspiracy theories surrounding these events. Research into the psychology of conspiracy theory beliefs is ongoing, with some studies suggesting that there are stable individual differences in the tendency to believe in conspiracies. As we approach this significant anniversary, it is important to engage with sources that provide a nuanced understanding of the events of that day and the complex factors that have contributed to the emergence and persistence of conspiracy theories.
