Understanding Public Views on Immigration"},"content":{"rendered":"

You might think that most people have misperceptions about immigration. Yet many false beliefs are merely low-confidence guesses, rather than firmly held views. New Swiss survey evidence shows that this distinction has important implications for understanding public opinion and for the quality of democratic debate.\u00a0<\/strong><\/p>\n

Public debate is quick to conclude that many people harbor entrenched false beliefs about immigration. From inflated estimates of immigrant numbers to exaggerated ideas about crime or welfare use, we tend to treat misperceptions as common\u00a0and\u00a0consequential. This is not entirely unfounded. But our latest research, published in\u00a0Political Science Research and Methods<\/strong><\/a>, suggests a different and considerably more\u00a0mundane explanation: many of these\u00a0supposed misperceptions are,\u00a0first and foremost, just the product of bad guessing.<\/p>\n

This distinction matters. A confidently held false belief has\u00a0a very different political life from a tentative, low-confidence estimate given by someone who has never thought much about the issue. But most survey approaches to measuring\u00a0perceptions\u00a0fail to\u00a0make this distinction. They tend to treat both response categories as identical, with severe consequences. For when we do not distinguish misperceptions from uninformedness, we risk overstating the scale of the problem while also misunderstanding its causes and consequences.<\/p>\n

And there\u00a0is a second, more issue-specific problem. Scholars have long relied on a single question to gauge perceptions\u00a0of immigration: asking respondents to estimate the immigrant share of the local or national population. This, of course, is a sensible starting point, because the number is easy to communicate and politically salient.<\/p>\n

Yet it has also\u00a0come to function as\u00a0a conceptual crutch, given that immigration is a multidimensional phenomenon,\u00a0while\u00a0the measurement of perceptions remains strikingly narrow. It conflates genuine misperceptions with general innumeracy, the difficulty of interpreting numerical information, which may distort our understanding of what the public\u00a0actually believes.<\/p>\n

A Broader Battery and a Simple Question\u00a0<\/strong><\/p>\n

To address both problems, we developed a new module, administered in a Swiss population survey, that broadens not only which questions we ask but also how we capture perceptions.<\/p>\n

First, we move beyond the standard item on the population share of immigrants by including six perception\u00a0questions across three different dimensions: culture, economy,\u00a0and security. All three capture issues that surface routinely in public debate, from the immigrant unemployment rate to the share of immigrants holding university degrees. In this way, we gain a more comprehensive picture of how citizens form their views on immigration.<\/p>\n

Our survey module separates actual false beliefs from uninformed guesses, helping to close the gap between the conceptualization of misperceptions and their empirical measurement.<\/p>\n

Second, we paired each\u00a0perception\u00a0item with a confidence scale. After giving their estimate, we asked respondents a follow-up:\u00a0How confident are you that this estimate is correct?<\/p>\n

This allows us to construct two distinct measures, namely genuine misperceptions (inaccurate answers given with high confidence) and bad guesses (inaccurate answers given with low confidence). In other words, we can separate actual false beliefs from uninformed guesses and thereby help close the gap between the conceptualization of misperceptions and their empirical measurement.<\/p>\n

Guessing Dominates\u00a0<\/strong><\/p>\n

Across all items, respondents offer estimates that vary widely, at times overshooting and at times underestimating the official figures.\u00a0At first glance, this\u00a0variation\u00a0appears to confirm\u00a0the familiar story of widespread misperceptions. Yet once we factor in confidence, a different pattern\u00a0emerges. For most items, a substantial number of respondents express little to no confidence in their answers. Indeed, confidence levels are\u00a0generally low, so that inaccurate responses fall predominantly into\u00a0the area of guesses rather than genuine misperceptions.<\/p>\n

Crucially, misperceptions and guesses are also structured differently at the attitudinal level: people with more negative views of immigration tend to exhibit higher misperception scores, consistent with established theories of motivated reasoning. Guessing, by contrast, shows no such pattern. It is essentially a random error. This underscores that only misperceptions \u2014 not guesses \u2014 bear the imprint of political predispositions.<\/p>\n

Even when surveys register a wildly inaccurate estimate, this need not signal an ideological stance. More often, it reflects limited knowledge, indifference to such knowledge, or\u00a0simply\u00a0a respondent\u2019s difficulty in handling numerical information. Such inaccuracies frequently\u00a0stem from the improvised nature of on-the-spot responding. People provide their best estimate simply because the survey demands a reply.<\/p>\n

Average Misperception and Guessing by Item<\/p><\/div>\n

Rethinking the Narrative of a\u202fMisperceiving Public\u00a0<\/strong><\/p>\n

This changes how we should interpret the magnitude and character of misperceptions about immigration. To begin with, the problem may be mischaracterized. If only a small minority of inaccurate responses arise from high-confidence beliefs, then the popular claim that people are deeply and chronically misinformed warrants some reconsideration. In many instances, respondents are not rejecting empirical reality but navigating it with only a partial sense of the relevant figures.<\/p>\n

That said, knowledge may likewise be overstated:\u00a0some people gave correct answers with low confidence too. This suggests that accuracy may equally result from lucky\u00a0guessing rather than informed beliefs. The well-informed citizen, once central to democratic theory, appears as elusive as ever these days, and such blurring of accuracy and uncertainty only complicates how we infer competence from survey responses. Providing citizens with straightforward information may be more effective than commonly thought, especially when targeted at the unsure.<\/p>\n

This distinction carries significant implications for policy and political communication. Were all false answers misperceptions, any attempt to correct them would have to contend with motivated reasoning and identity-driven beliefs. But if many arise from uncertainty instead, straightforward information provision may be more effective than commonly thought, especially when targeted at the unsure rather than the already certain.<\/p>\n

In the end, our evidence points to the conclusion that many errors commonly attributed to misinformation and ideology rest on shaky\u00a0foundations. Rather than\u00a0representing\u00a0entrenched worldviews, many of these inaccuracies turn out to be houses of sand: they collapse once we\u00a0take into account\u00a0how limited respondents\u2019 confidence often is. If we\u00a0fail to\u00a0separate beliefs from guesses, we risk battling ghosts and misconstruing\u00a0uncertainty or confusion as political commitment.<\/p>\n
