Davison's hypothesis
Davison (1983) recounted a World War II episode in which Japanese forces dropped leaflets on a U.S. unit with many Black soldiers, claiming the war was a white man's war; although the soldiers themselves were not swayed, their white officers withdrew the unit. He argued that people believe persuasive messages affect "them", third persons, more than "me" or "you", and act on that belief. The hypothesis has two parts: the perceptual hypothesis, that people judge the influence on others to be greater than on themselves, and the behavioral hypothesis, that this perception leads to actions such as support for censorship.
Why it occurs
The most cited explanation is self-enhancement: wanting to see oneself as smarter and less gullible than others, people attribute the influence of undesirable messages to others, a pattern linked to the self-serving bias. Gunther (1991) reported that overestimating others' exposure and vulnerability also plays a role. A social distance corollary has been reported, in which the perceived effect grows for groups seen as socially distant, and Duck, Hogg and Terry (1995) showed that political identification led people to see out-group voters as more swayed by campaign ads. Eveland and colleagues (1999) reinterpreted part of this distance effect as stemming from expectations that such groups are more exposed to the message. Conversely, for desirable messages such as public service campaigns, a first-person effect appears in which people see themselves as more influenced (Golan and Day, 2008).
Meta-analyses and behavioral consequences
Reviewing early research, Perloff (1993, 1999) concluded that the perceptual hypothesis is very consistently supported while the behavioral hypothesis is weaker. Meta-analyses by Paul, Salwen and Dupagne (2000) and by Sun, Pan and Shen (2008) likewise found the third-person perception robust and larger for less desirable messages. On the behavioral side, Gunther (1995) showed that the more harm people saw pornography doing to others, the more they supported censorship. Gunther and Storey (2003) broadened this into the influence of presumed influence model, in which the mere assumption that media affect others changes people's behavior. Jang and Kim (2018) reported that people who saw greater fake news effects on others differed in their support for regulation versus interventions such as media literacy education. The concept is studied in media effects research alongside agenda-setting theory, cultivation theory and the spiral of silence.
FAQ
- What is the third-person effect in simple terms?
- It is the tendency to think that ads or fake news will not fool me but will fool other people. This belief can change actual behavior, such as supporting regulation or censorship.
- Does the third-person effect always appear?
- The perception that others are more influenced is consistently confirmed in meta-analyses, but it varies with the type of message. The gap is larger for harmful or undesirable messages, and for desirable messages such as public service campaigns, a first-person effect may appear in which people see themselves as more influenced.
