The evolution of economic and political inequality: minding the gap.

The extent of economic and political inequality, their change over time, and the forces shaping them have profound implications for the sustainability of a society and the well-being of its members. Here we review the evolution of economic and political inequality broadly, though with particular attention to Europe and the USA. We describe legal/institutional, technological and social forces that have shaped this evolution.

Risk of disease and willingness to vaccinate in the United States: A population-based survey.

Background: Vaccination complacency occurs when perceived risks of vaccine-preventable diseases are sufficiently low so that vaccination is no longer perceived as a necessary precaution. Disease outbreaks can once again increase perceptions of risk, thereby decrease vaccine complacency, and in turn decrease vaccine hesitancy. It is not well understood, however, how change in perceived risk translates into change in vaccine hesitancy.

The effect of trust and proximity on vaccine propensity.

The main goal of this paper is to study the effects of (1) trust in government medical experts and (2) proximity to a recent disease outbreak on vaccine propensity. More specifically, we explore how these variables affect attitudes with regards to measles. Using original survey data, collected in January/February 2017, we obtain three main empirical findings.

The influence of political ideology and trust on willingness to vaccinate.

In light of the increasing refusal of some parents to vaccinate children, public health strategies have focused on increasing knowledge and awareness based on a "knowledge-deficit" approach. However, decisions about vaccination are based on more than mere knowledge of risks, costs, and benefits. Individual decision making about vaccinating involves many other factors including those related to emotion, culture, religion, and socio-political context.

Social media echo chambers and satisfaction with democracy among Democrats and Republicans in the aftermath of the 2016 US elections.

There is widespread evidence that individuals select information that supports their convictions and worldviews. This behavior yields the formation of echo chambers - environments in which an individual's own political beliefs are repeated and amplified and dissenting opinions are screened out. Recent research demonstrates that social networking sites (SNS) such as Facebook or Twitter can facilitate this selection into homogenous networks.

The public's trust in scientific claims regarding offshore oil drilling.

Our study examines how individuals decide which scientific claims and experts to believe when faced with competing claims regarding a policy issue. Using an experiment in a public opinion survey, we test the source content and credibility hypotheses to assess how much confidence people have in reports about scientific studies of the safety of offshore oil drilling along the California coast. The results show that message content has a substantial impact.
