Social psychological factors of post-mortem organ donation: a theoretical review of determinants and promotion strategies

A recurrent observation in the field of organ donation is that organ demand exceeds supply. Organ donation promotion is therefore required in order to diminish this gap. In this article, we focus on post-mortem organ donation and review psychosocial literature contributing to identify firstly, the determinants of donation, and secondly, the factors likely to increase the efficiency of donation promotion campaigns. Finally, we discuss the theoretical implications of our review and advance promising avenues for future research.

Democracy as Justification for Waging War: The Role of Public Support

Democracy is positively valued. This positive evaluation extends to a democracy’s actions, even if it is to wage war. The authors investigated whether the perceived legitimacy of military interventions depends on the political structure (democratic vs. nondemocratic) of the countries involved and on the aggressor country’s popular support for the government’s aggressive policy. Participants learned that an alleged country planned to attack another. The political structure of both countries was manipulated in the two experiments. The support of the aggressor’s population toward military intervention was measured in Experiment 1 and manipulated in Experiment 2. Both experiments confirmed that military intervention was perceived as being less illegitimate when the population supported their democratic government’s policy to attack a nondemocratic country.

Do all lives have the same value? Support for international military interventions as a function of political system and public opinion of target states

This research examined the support for international military interventions as a function of the political system and the public opinion of the target country. In two experiments, we informed participants about a possible military intervention by the international community towards a sovereign country whose government planned to use military force against a secessionist region. They were then asked whether they would support this intervention whilst being reminded that it would cause civilian deaths. The democratic or nondemocratic political system of the target country was experimentally manipulated, and the population support for its belligerent government policy was either assessed (Experiment 1) or manipulated (Experiment 2). Results showed greater support for the intervention when the target country was nondemocratic, as compared to the democratic and the control conditions, but only when its population supported the belligerent government policy. Support for the external intervention was low when the target country was democratic, irrespective of national public opinion. These findings provide support for the democracy-as-value hypothesis applied to international military interventions, and suggest that civilian deaths (collateral damage) are more acceptable when nondemocratic populations support their government’s belligerent policy.

The Partisan Brain: An Identity-Based Model of Political Belief

Democracies assume accurate knowledge by the populace, but the human attraction to fake and untrustworthy news poses a serious problem for healthy democratic functioning. We articulate why and how identification with political parties - known as partisanship - can bias information processing in the human brain. There is extensive evidence that people engage in motivated political reasoning, but recent research suggests that partisanship can alter memory, implicit evaluation, and even perceptual judgments. We propose an identity-based model of belief for understanding the influence of partisanship on these cognitive processes. This framework helps to explain why people place party loyalty over policy, and even over truth. Finally, we discuss strategies for de-biasing information processing to help to create a shared reality across partisan divides.

Collective Apologies Moderate the Effects of Justice Concerns on Support for Collective Punishment

Following an offense, various justice concerns arise, and people might support the punishment of the offender’s entire group to restore a sense of justice (even if the other group members are innocent). We hypothesized that support for collective punishment might increase along one’s justice concerns, and that such effect can be hindered by the group’s collective apologies. In three studies, third-party observers were presented with various cases of aggression and we measured (Study 1) or manipulated (Studies 2 and 3) their justice concerns. In all studies, the presence (vs. absence) of collective apologies was additionally manipulated. The results confirmed our hypothesis thereby increasing our knowledge of both the determinants of collective punishment and the potential effects of collective apologies.
