We conduct an online survey to explore how Chinese people living in Germany perceive and react to group criticism in the context of the debate on the Wuhan Diary, a chronicle about life during the lockdown in Wuhan. We find that the majority rating of the book is a lukewarm "neither like nor dislike." Most participants are open to criticism in principle and do not agree that the book only spreads so-called "negative-energy". However, many participants were skeptical about the objectivity of the book and concerned about its potential use by so-called anti-China forces, even though the degree of blind patriotism is relatively low in our sample. The factors influencing the book's evaluation are intriguing: perceived Western sentiment, media exposure and uncritical patriotism all affect COVID-19-related conspiracy beliefs, which in turn lead to a more negative evaluation of the book. A cluster analysis reveals two groups which differ in terms of properties like blind patriotism, belief in certain conspiracies, and also demographic parameters. Our results shed light on identity politics, motivated beliefs, and collective narcissism.

The worldwide COVID-19 pandemic puts countries and their governments in an unprecedented situation. Strong countermeasures have been implemented in most places, but how much do people trust their governments in handling this crisis? Using data from a worldwide survey, conducted between March 20th and April 22nd, 2020, with more than 100,000 participants, we study people's perceptions of government reactions in 57 countries. We find that media freedom reduces government trust directly as well as indirectly via a more negative assessment of government reactions as either insufficient or too strict. Higher level of education is associated with higher government trust and lower tendency to judge government reactions as too extreme. We also find different predictors of perceived insufficient reactions vs. too-extreme reactions. In particular, number of COVID-19 deaths significantly predicts perceived insufficient reactions but is not related to perceived too-extreme reactions. Further survey evidence suggests that conspiracy theory believers tend to perceive government countermeasures as too strict.

Can television have a mitigating e.ect on xenophobia? To examine this question, we exploit the fact that individuals in some areas of East Germany . due to their geographic location . could not receive West German television until 1989. We conjecture that individuals who received West German television were exposed more frequently to foreigners and thus have developed less xenophobia than people who were not exposed to those programs. Our results show that regions that could receive West German television were less likely to vote for right-wing parties during the national elections from 1998 to 2013. Only recently, the same regions were also more likely to vote for left-wing parties. Moreover, while counties that hosted more foreigners in 1989 were also more likely to vote for right-wing parties in most elections, we find counties that recently hosted more foreign visitors showed less xenophobia, which is in line with intergroup contact theory.
