  In the preceding section, we saw how the rapid spread of Fake News online raises one kind of trust-related concern for SECs: the accuracy of the information on some sites to which search engine users are directed. We next briefly examine the concept of trust in more general terms, before considering whether and how it might be possible for users to enter into trust relationships with SECs. As in the case of other key ethical issues affecting SECs, it is not possible to discuss here the many aspects of trust in the detail that they would otherwise warrant. For an excellent overview of trust (in general), see McLeod (2015). We limit our analysis to some current trust-related issues involving SECs, and suggest that the way SECs respond to these issues could affect the sense of trust that users will have in the future for major SECs such as Google and Bing.
