Last Friday, President Trump issued an executive order temporarily barring entry of refugees, visitors, and immigrants—including those with green cards—from Syria, Iraq, Iran, Libya, Somalia, Sudan, and Yemen. During this delay, the government is tasked with making its screening process more extensive. The order indefinitely bans refugees from Syria.
As Henry Enten notes, we’ll have to wait until we have more polling data to ascertain how the public will judge the action, but polling over the past year gives us some clues.
Slim but Shy Support Most polls throughout 2015-2016 found about 56% of Americans opposed Trump’s call to temporarily ban Muslim immigrants from entering the United States. However, these polls tended to be conducted by live telephone interviewers. In contrast, polls conducted online by reputable firms like YouGov and Morning consult, find a plurality of Americans in support.
Aggregating over 40 telephone and online polls conducted over the past two years finds Americans opposed to the ban 56% to 39% in surveys conducted by phone, but a plurality in support 49% to 39% in surveys conducted online. This suggests that people taking surveys by phone feel uncomfortable sharing their true feelings and thus fib to the live interviewers. But, privately taking a survey online encourages people to share what they really think. In the polling world, this is called “social desirability bias” evoked by social pressure to not appear prejudiced to the live interviewer.
Of course, the difference cannot be entirely attributed to survey mode since the questions weren’t worded the exact same way. Nonetheless, it’s suggestive that there is a “shy immigration restrictionist” effect going on. (Remember the shy Trump voter?)
Americans Don’t Support an Outright Ban on Refugees Existing data suggest Americans do not support a permanent ban on refugees. Most telephone and online surveys found that Americans oppose not taking any refugees at all and a plurality (46%) say the “US should open our borders to refugees of foreign conflicts” according to an Ipsos/Reuters Jan 2017 online survey. At the same time, Americans tend to support taking fewer refugees rather than more, when given the option. For instance, both an Ipsos/Reuters Jan 2017 online survey and a Marist Apr 2016 telephone survey found 53% of Americans want the US to take in fewer refugees.
Wording Impacts Support Strength As you can imagine, survey question wording impacts responses. Support for immigration restriction increases when refugees and immigrants are described as coming from “terror prone regions” or when respondents are told that government needs time to enhance security measures. For instance, Rasmussen, measures the highest degree of support (57%) when it asked if respondents support or oppose a “temporary ban on refugees from Syria, Iraq, Iran, Libya, Somalia, Sudan, and Yemen until the federal government improves its ability to screen out potential terrorists from coming here.” This question presupposes the government screening system is already poor and the new administration could meaningfully improve it. If these are the assumptions going in, support will be higher. When national security concerns are invoked and at the top of people’s minds they are more supportive of immigration restrictions.
Support for immigration restriction decreases, however, when the described policy implies a religious test. Surveys register lower support (48%) if the policy is described as a “temporary ban on all Muslims traveling to the United States” (from Morning Consult).
