Three levels of trust as a social psychological construct are delineated: trust in a specific person (relational trust), trust in people in general (generalised trust) and trust in abstract systems. Whereas much research is available on relational trust and generalized trust, much less is known about trust in systems. From theory and research several assumptions are derived which are related to the development of trust in the Internet. For example, the reliability of information technology is assumed to be directly related (...) to the development of trust in the Internet. In addition, it is assumed that in situations in which it is hard to verify the justification for trust, people construct subjective beliefs which represent a transformation of relational trust into system trust. Applications of these assumptions for strengthening the trustworthiness of the Internet are discussed. (shrink)

The hypothesis that experiencing extreme weather events can affect environmental concerns have long been discussed, yet rarely investigated. In a unique before and after design, 122 residents in Florida USA answered survey questions before and after experiencing hurricane Irma in September, 2017. After experiencing Irma, Floridians reported higher levels of negative emotions when thinking about climate change, a strengthened belief that Irma was caused by global warming, and they expressed greater willingness to sacrifice (e.g., pay higher taxes for the sake (...) of the environment). In addition, a mediation analysis found that for extreme weather experiences to result in pro-environmental actions, people need to feel that this experience was negative and think that they ought to do something about climate change.
