Show moreBitcoin was invented to serve as a digital currency that demands no trust in financial institutions, such as commercial and central banks. This paper discusses metaphysical aspects of bitcoin, in particular the view that bitcoin is socially constructed, non-concrete, and genuinely exists. If bitcoin is socially constructed, then one may worry that this reintroduces trust in the communities responsible for the social construction. Although we may have to rely on certain communities, I argue that social construction doesn’t imply a demand for trust because the relevant communities don’t take on any relevant commitments. Bitcoin is indeed trust-free. Show less

Show moreIn this article, we inquire to what extent different manifestations of trust are associated with public support for evidence informed policy making (EIPM). We present the results of a cross-sectional survey conducted in the peak of the second COVID-19 wave in six Western democracies: Australia, Belgium, Canada, France, Switzerland, and the United States (N = 8749). Our findings show that public trust in scientific experts is generally related to positive attitudes toward evidence-informed policy making, while the opposite is the case for trust in governments and fellow citizens. Interestingly, citizens' assessment of government responses to COVID-19 moderates the relationship between trust and attitudes toward EIPM. Respondents who do rather not trust their governments or their fellow citizens are more in favor of EIPM if they evaluate government responses negatively. These findings suggest that attitudes toward EIPM are not only related to trust, but also strongly depend on perceived government performance. Show less

Show moreObjectives: Tailoring medical information to cancer patients' needs is recommended, but there is little guidance on how to tailor, and limited research exists about its effects. Tailoring to the amount of preferred information may be easily implementable in clinic and is tested here.Methods: A video-vignette experiment was used to systematically vary video patients' information preferences (limited/extensive) and amount of provided information (additional/no additional). N= 253 cancer patients/survivors evaluated these video-recorded consultations, serving as analogue patients (APs), and completed outcome measures.Results: Tailoring information to video patients' preferences had no effect on APs' evaluation of the consultation (satisfaction, trust). Yet, there was a main effect of APs' own information preferences: Those preferring extensive information recalled (M Delta = 5.8%) and recognized (M Delta = 3.5%) more information than those preferring limited information. Moreover, information provision mattered among APs who preferred limited information: They recognized even less if provided with extensive information.Conclusions: Tailoring to the amount of video patient's information preferences did not affect APs' evaluation of the consultation (satisfaction, trust), while APs' personal information preferences determined their recall and recognition of medical information.Practice implications: Information preferences should be assessed and tailored to in clinical practice. Overwhelming patients/survivors, who prefer limited information, should be prevented. (C) 2019 Elsevier B.V. All rights reserved. Show less

Show moreIndividuals suffering from depression often have difficulty trusting others. Previous research has shown a relationship between trust formation and pupil mimicry - the synchronization of pupil sizes between individuals. The current study therefore examined whether pupil mimicry is weaker in depressed individuals and an underlying factor of their low levels of trust. Forty-two patients with major depressive disorder (MDD) and 40 healthy control subjects played trust games with virtual partners. Images of these partners' eye regions were presented to participants before they had to make a monetary investment decision. Partners' pupils either dilated, constricted, or remained static over the course of 4-s interactions. During the task, participants' pupil sizes were recorded with eye-tracking equipment to assess mimicry. The results confirm that patients with MDD were somewhat less trusting than controls and used another's pupillary cues differently when deciding to trust. Specifically, whereas healthy controls trusted partners with dilating pupils more than partners with constricting pupils, patients with MDD particularly trusted partners whose pupils changed in size less, regardless of whether partners' pupils were dilating or constricting. This difference in investment behavior was unrelated to differences in pupil mimicry, which was equally apparent in both groups and fostered trust to the same extent. Whereas lower levels of trust observed in patients with MDD could not be explained by differences in pupil mimicry, our data show that pupil dilation mimicry might help people to trust. These findings provide further evidence for the important role of pupil size and pupil mimicry in interpersonal trust formation and shed light on the pathophysiology of clinically low trust in patients with MDD.

Show moreWhen do recipients of an apology (“trustors”) base their decision to trust a perpetrator (a “trustee”) on the attributional information embedded in an apology? Attributions provide a detailed account of the trustee's causal involvement in committing a transgression. We therefore argue that trustors in a low construal level mindset use this information in their trusting decision. However, trustors in a high construal level mindset likely consider all apologies as simple statements of regret, regardless of the attributional information they contain. We find support for this argument in four laboratory experiments. This research nuances the idea that to restore trust by means of an apology, the trustee must only use an effective attribution for a negative outcome. We also present a more realistic understanding of the process leading from apologies to trust than has been offered in previous work by simultaneously considering the role of the trustor and that of the trustee in the trust restoration process.

Show morePurposeThe original 18-item, four-dimensional Trust in Oncologist Scale assesses cancer patients’ trust in their oncologist. The current aim was to develop and validate a short form version of the scale to enable more efficient assessment of cancer patients’ trust.MethodsExisting validation data of the full-length Trust in Oncologist Scale were used to create a short form of the Trust in Oncologist Scale. The resulting short form was validated in a new sample of cancer patients (n = 92). Socio-demographics, medical characteristics, trust in the oncologist, satisfaction with communication, trust in healthcare, willingness to recommend the oncologist to others and to contact the oncologist in case of questions were assessed. Internal consistency, reliability, convergent and structural validity were tested.ResultsThe five-item Trust in Oncologist Scale Short Form was created by selecting the statistically best performing item from each dimension of the original scale, to ensure content validity. Mean trust in the oncologist was high in the validation sample (response rate 86%, M = 4.30, SD = 0.98). Exploratory factor analyses supported one-dimensionality of the short form. Internal consistency was high, and temporal stability was moderate. Initial convergent validity was suggested by moderate correlations between trust scores with associated constructs.ConclusionsThe Trust in Oncologist Scale Short Form appears to efficiently, reliably and validly measures cancer patients’ trust in their oncologist. It may be used in research and as a quality indicator in clinical practice. More thorough validation of the scale is recommended to confirm this initial evidence of its validity. Show less
