Theoretical roots and early debates
According to Festinger's (1957) cognitive dissonance theory, people feel discomfort when they hold inconsistent cognitions and try to reduce it. They therefore seek information consistent with decisions already made or beliefs already held and avoid information that would increase discomfort. Reviewing the experimental evidence of the time, however, Sears and Freedman (1967) argued that people do not necessarily avoid opposing information and that other factors, such as the usefulness of information or education, may matter more. Research declined for a while after this critique, but Frey (1986) concluded that selective exposure appears clearly under particular conditions, such as when decisions are irreversible or when people are strongly committed to their positions.
Evidence and partisan media
In a meta-analysis of 91 studies with some 8,000 participants, Hart and colleagues (2009) reported that people are nearly twice as likely to select information congenial to their views as uncongenial information. This tendency was stronger when people were more committed to the topic and weaker when opposing information was genuinely useful. In politics, Stroud (2008) showed that conservatives use more conservative-leaning media and liberals more liberal-leaning media. Iyengar and Hahn (2009) reported experimental evidence that respondents' choices among identical stories varied sharply with their partisanship depending on whether the stories were labeled as coming from Fox News, CNN or other outlets.
The echo chamber debate
As the internet and social media spread, concern grew that people would be trapped in echo chambers, hearing only like-minded opinions, or in filter bubbles in which algorithms show only personalized information. Garrett (2009), however, reported that online news users seek out opinion-reinforcing information more but do not actively avoid opinion-challenging information; seeking support and avoiding challenge are distinct phenomena. Selective exposure is closely related to confirmation bias and has underpinned the argument that media effects often reinforce rather than change existing attitudes. Researchers now see individual choice and platform design as jointly shaping exposure in an increasingly diverse information environment.
FAQ
- What is selective exposure in simple terms?
- It is the tendency to look for news and information that fit what we already think and to avoid information that does not, which makes existing views more likely to harden.
- How does selective exposure differ from confirmation bias?
- Selective exposure concerns which information we seek and encounter, while confirmation bias is a broader tendency to favor existing beliefs throughout searching, interpreting and remembering information. Selective exposure can be seen as one form of confirmation bias.
