Trust and distrust in contradictory information transmission.

ABSTRACT: We analyse the problem of contradictory information distribution in networks of agents with positive and negative trust. The networks of interest are built by ranked agents with different epistemic attitudes. In this context, positive trust is a property of the communication between agents required when message passing is executed bottom-up in the hierarchy, or as a result of a sceptic agent checking information. These two situations are associated with a confirmation procedure that has an epistemic cost. Negative trust results from refusing verification, either of contradictory information or because of a lazy attitude. We offer first a natural deduction system called SecureNDsim to model these interactions and consider some meta-theoretical properties of its derivations. We then implement it in a NetLogo simulation to test experimentally its formal properties. Our analysis concerns in particular: conditions for consensus-reaching transmissions; epistemic costs induced by confirmation and rejection operations; the influence of ranking of the initially labelled nodes on consensus and costs; complexity results.

Project description:IntroductionRecently, the rates of utilization of alternative tobacco products have increased. Providing health information about tobacco products from trustworthy sources may help decrease the popularity of these products. Using a nationally representative study of adults, we fill the current gap in research on racial and ethnic disparities in utilization of alternative tobacco products as well as in trust of sources of health information about tobacco products.Aims and methodsData came from the Health Information National Trends Survey (N = 3738), which was collected in 2015. Logistic regression models were used to calculate odds of use of seven different tobacco product (eg, hookah, e-cigarettes, etc.), trust in seven different sources of e-cigarette health information (eg, family or friends, health care providers, etc.), and trust in six different sources of tobacco health information, adjusting for control variables.ResultsThere were disparities in utilization of alternative tobacco products and in trust, in tobacco companies across racial and ethnic groups. Blacks and Asians were far more likely than whites to trust tobacco (adjusted odds ratios = 8.67 and 4.34) and e-cigarette companies (adjusted odds ratios = 6.97 and 3.13) with information about the health effects of e-cigarettes than whites.ConclusionsThe popularity of alternative tobacco products appears to be high and may offset recent observed decreases in cigarette use. Blacks and Asians appear to trust tobacco companies as sources of information when compared to whites.ImplicationsHigher levels of trust in tobacco companies among Asians and blacks may translate to greater susceptibility to utilize tobacco products among these groups, thereby increasing disparities. There is a need for social marketing and education efforts focused on increasing awareness of adverse health effects of using alternative tobacco products as well as on the untrustworthiness of tobacco and e-cigarette companies, especially among racial and ethnic minorities.
