Message credibility is a commonly used term to indicate how well the recipients approve the message. Source credibility, on the other hand is a “communicator's positive characteristics that affect the receiver's acceptance of a message” (Ohanian, 1990, pp 41). It has been stated that an effect is apparent between the two, therefore the purpose of this study is to describe the effect of source credibility characteristics; trustworthiness, expertise and attractiveness on message credibility. The study utilized a quantitative research approach in order to describe the effect between the concepts. The researchers used a Likert-scale online questionnaire as the data collection method. The findings of this research suggest that all of the characteristics within the source credibility model are proven to have a significant and positive effect on the message credibility.

Yes / In expert knowledge elicitation (EKE) for forecasting, the perceived credibility of an expert is likely to affect the weighting attached to their advice. Four experiments have investigated the extent to which the implicit weighting depends on the advisor’s experienced (reflecting the accuracy of their past forecasts), or presumed (based on their status) credibility. Compared to a control group, advice from a source with a high experienced credibility received a greater weighting, but having a low level of experienced credibility did not reduce the weighting. In contrast, a high presumed credibility did not increase the weighting relative to a control group, while a low presumed credibility decreased it. When there were opportunities for the two types of credibility to interact, a high experienced credibility tended to eclipse the presumed credibility if the advisees were non-experts. However, when the advisees were professionals, both the presumed and experienced credibility of the advisor were influential in determining the weight attached to the advice.

This experimental study examined the source-message congruence effect on source credibility by manipulating the congruence of the reviewer’s profile information (travel interest, geographical location) with no changes in the review content. the congruence effect was found to influence perceptions of the reviewer’s expertise in a travel interest. This finding suggests that revealing the reviewer’s travel interest can assist the credibility assessment of travel reviewers-particularly in terms of expertise-within the category of a travel interest. the refined classification of travel reviewers based on their travel interests can improve their usefulness as information sources for prospective travelers’ information searches. These attributes can further be employed as search cues if embedded in the reviewer’s profile.

In this thesis, information completeness and credibility in web auction environment is the mainly question to find out. By using focus group research method, three discussions were held. In the first discussion, there were six interviewers joined, and the discussing purpose was to understand the concept of information completeness and credibility in e-commerce. In the second discussion, two sellers were invited to demonstrate and to explain how to sell in online auction. In the third discussion, eight buyers were asked to introducing themselves, and discussing themselves cases about online shopping. Finally using oral analysis skills, the research framework was constructed. The research suggests that information completeness and credibility includes all about product information, retailers¡¦ information, transaction information, information representation and third parties information. Each has its different degree of credibility, and buyers usually retrieve information they need to reduce their perceived risk.

In broad terms — including a thief's use of existing credit card, bank, or other accounts — the number of identity fraud victims in the United States ranges 9-10 million per year, or roughly 4% of the US adult population. The average annual theft per stolen identity was estimated at $6,383 in 2006, up approximately 22% from $5,248 in 2003; an increase in estimated total theft from $53.2 billion in 2003 to $56.6 billion in 2006. About three million Americans each year fall victim to the worst kind of identity fraud: new account fraud. Names, Social Security numbers, dates of birth, and other data are acquired fraudulently from the issuing organization, or from the victim then these data are used to create fraudulent identity documents. In turn, these are presented to other organizations as evidence of identity, used to open new lines of credit, secure loans, “flip” property, or otherwise turn a profit in a victim's name. This is much more time consuming — and typically more costly — to repair than fraudulent use of existing accounts. This research borrows from well-established theoretical backgrounds, in an effort to answer the question – what is it that makes identity documents credible? Most importantly, identification of the components of credibility draws upon personal construct psychology, the underpinning for the repertory grid technique, a form of structured interviewing that arrives at a description of the interviewee’s constructs on a given topic, such as credibility of identity documents. This represents substantial contribution to theory, being the first research to use the repertory grid technique to elicit from experts, their mental constructs used to evaluate credibility of different types of identity documents reviewed in the course of opening new accounts. The research identified twenty-one characteristics, different ones of which are present on different types of identity documents. Expert evaluations of these documents in different scenarios suggest that visual characteristics are most important for a physical document, while authenticated personal data are most important for a digital document.

Along with the Internet and the increased flow of information that follows, it’s now a fact thateveryone have the ability to publish information that could theoretically reach hundreds ofthousands of people. Several studies point to similar problems and believe that Internet usersgenerally lack the knowledge required to assess the credibility of various web content. Thismeans that the need for a tool to help users with web credibility assessment have never beengreater. With this report we try to study the effects this kind of tool would have on the usersand to what extend they are affected by it. We have performed a quantitative survey study inwhich the majority of the questions concerning which one of two news articles therespondents considered to be the most reliable. This was done in between two groups thatwould act as control groups for one another. They were also unaware of each other’sexistence and the respondents were recruited voluntarily through Facebook. The study showsthat visual representation of articles web credibility has little to no effect on the subjectsresponses apart from two major genres. Future studies should examine these specific genresand their impact on web credibility assessment.
