Tossing a Coin
The discussion about the fair allocation of scarce medical resources through triage decisions gained momentum during the COVID-19 pandemic. Ethical experts proposed to maximize the overall treatment benefits by prioritizing patients with the highest estimated post-treatment length of life, and apply a random lottery if the estimated post-treatment length of life for two patients is equal. However, implementing expert ethics requires the procedure…
Social Desirability Bias in Measures of Norm Violations and Compliance during the Covid-19 Pandemic
Social desirability bias is a problem in surveys collecting data on norm violations and compliance. If confronted with sensitive questions, respondents systematically underreport norm violations and overreport norm compliance. This leads to biased survey estimates and poor data quality. To improve the measurement of norm violations and compliance, the item count technique (ICT) has been developed. The ICT anonymizes the question-and-answer proces…
Fair allocation of resources in the moral dilemma of triage
Against the background of the COVID-19 pandemic that has shaken societies around the world, the debate about fairness of medical allocation decisions is gaining momentum. Studying a sample of a broad international public ( N = 1,998), we investigate citizens' ethical preferences in the moral dilemma of triage decisions. First, we address the key problem of which of several contradictory ethical criteria and normative principles should be used to …
Social class and moral judgment
Do social classes differ in moral judgment? Previous research showed that upper-class actors have a greater inclination toward utilitarian judgments than lower-class actors and that this relationship is mediated by empathic concern. In this paper, we take a closer look at class-based differences in moral judgment and use the psychometric technique of process dissociation to measure utilitarian and deontological decision inclinations as independen…
Triage in Times of Covid-19
We present evidence from choice experiments on hypothetical triage decisions in a pandemic. Respondents have to decide who out of two patients gets ventilation. Patients are described in terms of attributes such as short-term survival chance, long-term life expectancy, and their current ventilation status. Attributes are derived from the ethical discourse among experts regarding triage guidelines during the COVID-19 pandemic and differ in the ext…

Sensitive Questions and Trust
The randomized response technique (RRT) is an indirect question method that uses stochastic noise to increase anonymity in surveys containing sensitive items. Former studies often implicitly assumed that the respondents trust and comply with the RRT procedure and, therefore, are motivated to give truthful responses. However, validation studies demonstrated that RRT may not always be successful in eliciting truthful answering—even when compared wi…

Der vorliegende Beitrag geht der Frage nach, wie das Ausmaß von Schwarzarbeit in Deutschland im Rahmen von Befragungen der allgemeinen Bevölkerung mçglichst valide geschätzt werden kann. In einem experimentellen Design wird die konventionelle direkte Befragungstechnik mit zwei Spezialtechniken, der Randomized-Response- Technik (RRT) und der Item-Count-Technik (ICT), verglichen. Die RRTund die ICT wurden für die Messung besonders heikler Verhalten…
Estimating the prevalence of xenophobia and anti-Semitism in Germany
Asking Sensitive Questions Using the Crosswise Model
Yu, Tian, and Tang (2008) proposed two new techniques for asking questions on sensitive topics in population surveys: the triangular model (TM) and the crosswise model (CM). The two models can be used as alternatives to the well-known randomized response technique (RRT) and are meant to overcome some of the drawbacks of the RRT. Although Yu, Tian, and Tang provide a promising theoretical analysis of the proposed models, they did not test them. We…
Entstehungsbedingungen sozial erwünschten Antwortverhaltens
Aber es gibt keine Antisemiten mehr“
Die öffentliche Sanktionierung des Antisemitismus nach 1945 hat dazu geführt, dass antisemitische Einstellungen in der bundesdeutschen Öffentlichkeit selten offen geäußert werden, teilweise jedoch im privaten Raum überdauern. Diese Entwicklung wurde von der Antisemitismusforschung zwar theoretisch mit dem Konzept der „Kommunikationslatenz“ aufgearbeitet, methodisch blieben diese Überlegungen jedoch weitgehend folgenlos. Aufgrund des heiklen Chara…
Die Durchsetzung sozialer Normen in Low-Cost und High-Cost Situationen / Enforcement of Social Norms in Low-Cost and High-Cost Situations
In Feldstudien konnte häufig mittels der Low-Cost Hypothese gezeigt werden, dass normkonformes Verhalten von den dafür aufzuwendenden Kosten abhängt. Doch die Gültigkeit der Low-Cost Hypothese ist bei der Durchsetzung sozialer Normen bislang wenig erforscht. In unserer Studie werden diese kollektiven Güter zweiter Ordnung anhand nachbarschaftlicher Kontrollen analysiert. Es werden Daten einer postalischen Befragung von 631 Personen in Leipzig aus…
