Perception of Experts & Non-experts and Impacts on Attitude
Jae-Min Jung* and Ho-Yeon Kim** Abstract: The third-person effect was tested by examining whether people perceive a greater influence of
unidentified information recommending stocks in the Internet on others than on themselves. Findings
confirm the third-person effect but also show subjects with stock market experience perceive a greater
influence on others than did subjects with no stock market experience. Additionally, subjects
demonstrated a larger third-person effect when "others" are specified as novice investors who have little
knowledge or experience in stock trading than when "others" are identified as experienced traders. After
controlling for SES and interest and experience in stock trading, the third-person perception remained.

Pfizer's stock has climbed 20%."Of course, the people touting a stock may be company insiders or In his seminal study, Davison (1983) introduced paid promoters who stand to profit at consumers' an interesting example about the third person effect: expense. Thus, when people see an offer on the "Fluctuations in the stock market are not infrequently Internet, they have to determine its legitimacy accounted for by reference to rumors or news reports. through their own independent research.

Based on the third-person effect theory, the perceptual discrepancies. perceptions of general individuals and that of experts First, perceptions rely on the desirability of the who work at stock trading companies will be message. Self-enhancement theorists assert that compared. In other words, we will compare if people are loathe to admit that they are influenced by individuals who do not have much knowledge and messages when such admission reflects negatively on information and the experts whose daily job is the self. Third-person effects should be particularly analyzing stock market perceive information pronounced when the message is perceived as differently. This study also analyzes whether the undesirable (Perloff, 2009). For example, when the perception about the influence on people's buying messages are undesirable such as television violence, decision leads to behavioral aspects – whether pornography, negative political advertising or anti individuals support warnings or regulations about social rap music, the perceived effects on others are greater (Cohen et al., 1988; Eveland & McLeod, Data utilized here come from survey responses of 1999; Gunther & Mundy, 1993; Hoffner, et al., 1999; 335 professional stock market traders, adults and Lee & Tamborini, 2005; Perloff, 1999). The opposite side to these finding is also possible. According to a self-enhancement view, if the third- person effect is driven by a desire to preserve self- LITERATURE REVIEW

According to the fundamental no effort to break down into smaller parts. However, attribution error, observers generally underestimate the magnitude of the third-person effect hinges on the other people's awareness of situational factors such particular others that observers have in mind when as the persuasive intent of media content and, thus, they estimate media effects (Perloff, 2009). For overestimate other's susceptibility to this content. But example, the third-person effect increases as others in judging themselves, observers are quite aware of become increasingly general (e.g., others in this the persuasive intent and are less susceptible to these classroom, others in this university, others in this message effects. Observers may also engage in self- town, others in this state) and hence more socially positivity bias or egotistical differential attributions distant (Cohen, Mutz, Price, & Gunther, 1988; Jensen (Miller, 1976; Stephan & Gollwitzeer, 1981).

That is, according to the Huh & Langteau, 2007; Lasorsa, 1989). perceived knowledge, expertise, or degree of involvement for each topic, people perceive the effects on others differently.

In other words, people are smarter and The first set of hypotheses tested here examine less vulnerable to media influence than are others whether the third-person effect can be applied to the (Eveland, 2002). Applying this notion, individuals use of advice in Internet content devoted to the stock with special knowledge concerning a topic and market. Thus, considering Davison's initial notion, awareness of a message creator's intent are likely to this study tests the third-person effect in a new think that their knowledge protects them from media domain: the stock market, or whether people perceive influence whereas others who are less knowledgeable greater impacts of unidentified information are more susceptible to media influence and easily recommending stocks in the Internet on others than on themselves. Pacific Science Review, vol. 15, B, no 4, 2013, pp.48 58 H1a: Respondents are more likely to believe that According to the previous literature, the greater the unidentified information recommending stocks in perceived effect of media content, the more people the Internet has more influence on others than on support censorship for the content. Thus, we predict a similar outcome here. When measuring the perception of third person, H2a: The greater the perceived effect of unidentified "other" was broken down into the specified groups as information recommending stocks in the Internet "novice investors," and "experienced investors."

Thus, the first three hypotheses were supported. Support for Censorship
