In a world where a reader must traverse through fake news and differentiate misinformation from truth, credibility becomes critical




Portfolio 4, Q. 1

Fogg (2003a, pp. 148, 149) highlights how the Internet can be a very credible source of information, but on the other hand, it can also entice with erroneous information. Lewandowski (2013, p. 132) suggests that credibility incorporates expertise and trustworthiness. Moreover, credibility relies on perception (Flanagan & Mezger, 2008, p. 8).  If the reader’s trust is broken then concepts like reputation, authority and reliability are severed (Stuart & Hooper, 2009, p. 235; Flanagan & Mezger, 2008, p. 8).  Moreover, Chete and Mbegbu (2012, p. 210) reiterate the negative effects of misinformation from the Internet. Perceptions of low quality control impact negatively on tertiary students (Chete & Mbegbu, 2012, p. 210). But on the other hand, credible sources create trust and consolidate the authority and expertise of the writer. As a student, I will return to those trusted sites that have built their credibility, because my perception of the information has been affirmed.

Shellenbarger (2016, November 21) highlights a Stanford study that found students appear to have trouble evaluating the trustworthiness and accuracy of internet news. Donald (2016, November 22), citing the same Stanford study as Shellenbarger (2016, November 21), highlights how students in the study were more likely to become consumed by the content rather than judge the source. The Stanford study reiterates the need as a student to assess the credibility, both in its trustworthiness and expertise.


Portfolio 4, Q. 2

Lih (2012, p. 331) suggests that Wikipedia is becoming recognized as a credible source, citing several media outlets who have quoted from Wikipedia sources. However, a citation in a newspaper is not evidence of credibility.  An online newspaper may seduce their readers with a perception of believability, but it does not always offer evidence of believability and accuracy (Abdulla et al., 2005, p. 150).

Lewandowski (2013, p. 132) recognizes that expertise is part of credibility. Anderson (2012, p. 146) reiterates that unreliability and authority are to blame for Wikipedia’s reputation for lack of credibility. Chesney (2006) notes that Wikipedia has warned that articles have the potential to fall prey to vandalism and to a writer’s agenda. Weinberger (2007, ch. 7) notes that Wikipedia’s credibility relies on an author’s contribution, but not their credentials.

Schneiderman (2015, p. 36) notes that Wikipedia places a lot of protections, guarding against erroneous news and eliminating threats. He suggests that such protection provide trust and credibility (Schneiderman, 2015, p. 40). However, Harvard University (“Harvard Guide”, 2017) argues that Wikipedia contributors are not filtered. Thus, the protections against writers with no expertise and no authority are weak.

Trustworthiness is one of the keys toward credibility (Fogg, 2003a, p. 124). Fitzgerald (2009, p. 181) highlights the inaccuracies that have sometimes plagued Wikipedia. He suggests that the posts can be unbalanced, sometimes lacking trustworthiness and tainted with bias (Fitzgerald, 2009, p. 181).


Portfolio 4, Q. 3

Fogg (2003b, p. 722) highlights how a consumer’s perception about the online service will determine whether their future use of the website.  But what are some of the issues that will affect the future perceived credibility of a website? Fogg (2003a, p. 154) hints at some of the future issues:

·         Bias perceived in the content

·         Typographical errors

·         Pop-up advertisements

·         Length of time for download

·         Confusion in name or website address creates confusion

·         Content not updated regularly

·         Online security

·         Professionalism of design

·         Customer service issues such as user feedback services and time of reply

·         Subscriptions

·         Links to other websites

·         Referencing untrustworthy sites

Lim (2014, p. 68) highlights how perceptions of credibility are important in shaping user attitude. These future issues are key toward shaping attitudes toward websites, especially customer service and design professionalism. Moreover, Lim (2014, p. 68) suggests that user confidence is formed through credibility. Issues such as security and bias will consolidate confidence.

Fogg (2003, p. 163) identifies four types of Website credibility, including presumed credibility, reputed credibility, surface credibility and earned credibility.

Presumed credibility is based on assumptions according to the reader’s perception. These assumptions steer the reader’s evaluation of the site.  A non-profit organization’s website is one example. It often ends with .org (Fogg, 2003, p. 164). One example of presumed credibility is Greenpeace steers the perceptions and assumptions of their readers with their website.

Reputed credibility rests on the endorsements of a third person (Fogg, 2003, p. 164). The site stands on the credibility of awards they have won and seals of approval. They are often linked to credible sites or companies. One example of reputed credibility is Allianz showcase their awards. They rest on their endorsements.

Surface credibility is based on first impressions. The website looks professional and constantly updated. An example of a website with surface credibility is The AFL constantly updates their website with the latest scores and up-to-date news stories.

Earned credibility ties the previous three together, providing fast customer service and recognizes your online presence. An example of earned credibility is The site remembers the books you have looked at and provides comprehensive customer service options.
