Facebook Hearings

Facebook has been under scrutiny after a whistle blower confirmed to congress that the social media platform is more concerned with profits than with the privacy or safety of its users. Critics of the platform claim that these revelations will push people to drop facebook as their social media platform. To test this claim we recorded people's willingness to stop using facebook. After that we showed people a summary of the whistle blower's testimony given to congress. The respondent's willingness was recorded once again. Please test the claim using the [facebook] dataset.

The War In Ukraine

The war in Ukraine has left the Western world on edge. Many are in favor of sending troops to Ukraine to help them against the Russian invasion. Others believe we should send troops

to observe the fight and ensure it impact our NATO allies. A third narrative is that this is not our war and not our problem so we should not get involved at all. War specialists have argued that liberals are in favor of sending troops while conservatives are in favor of not getting involved. Furthermore, they have argued that moderates are in favor of sending observing troops. Using the Ukraine data set, tells us what sense you can make of the claim linking support for deployment to political positions.

San Francisco Shooting

In a mass shooting in San Francisco, a man walked into a church and opened fire on the crowd, once again sparking an outcry for gun control. Psychologists argue that surviving a mass shooting event is one of the few powerful enough experiences to change one's opinion about gun control. To test that claim, we measured the support level for gun control of several San francisco residents, none of which ever experience a mass shooting. We also measured support levels for all survivors of the shooting. Use the data on the San Francisco Shootings tab to test this claim.

Bank Bailouts

Two California banks closely related to the Silicon Valley collapsed overnight, prompting a wave of fear that the economy is in bad shape. To avoid a panic, president Biden quickly put together a bailout package to stabilize these two banks. Conversations of bailouts are polarizing: some believe that bailouts are important because they keep the economy stable, while others are against it because it uses tax money to stabilize companies that should simply go under. Economists argue that if people were aware of the benefits of bailouts, they would support it. To test the claim that understanding the benefits of a bailout is enough to make people support it, we sampled a group of respondents, measuring their levels of support for bailouts. Respondents were then given a thorough explanation of the economic benefits of a bailout. We then measured their support levels once more. Using the data provided [Bailout tab], please test the claim.

Marijuana Legalization

Marijuana legalization is on the ballet again in several states. It has been argued that support for Marijuana is strong among young people, while older voters are against it. We collected data on support levels and age for a large sample of respondents. Please use the Marijuana tab to test this claim.

Infrastructure Bill

President Biden's infrastructure agenda has yet to reach enough support to pass congress. Supporters of the bill point out that those people who are aware of the precarious state of the American infrastructure are in favor of the bill, while those who are not aware do not support it. To test whether this claim is correct we recorded the levels of support for the infrastructure bill for several respondents. Some respondents were given a briefing on the current status of infrastructure, while others [who were not aware of it] were not briefed. Does awareness of the state of US infrastructure impact people's support of the bill. Use the infrastructure data to test the claim.\
