Experimental method

 

Experimental method refers to whether the experiment was conducted in a research laboratory, online, or in the field.

Occasionally, distinctions between the field and the scientific laboratory as a study or intervention are unclear. Paluck and Green (2009) offer this guidance for classification: "In an experimental design, units of observation (e.g., individuals, classrooms) are assigned at random to a treatment and to placebo or no-treatment conditions. Field experiments are randomized experiments that test the effects of real-world interventions in naturalistic settings, but the distinction between field and lab is often unclear. The laboratory can be the site of very realistic interventions, and conversely, artificial interventions may be tested in a nonlaboratory setting. When assessing the degree to which experiments qualify as field experiments, one must consider four aspects of the study: (a) participants, (b) the intervention and its target, (c) the obtrusiveness of intervention delivery, and (d ) the assessed response to the intervention."

Individual-level discrimination is often attributed to deep-seated prejudice that is difficult to change. But at the societal level, we sometimes observe rapid reductions in discriminatory preferences, suggesting that social interactions and the communication they entail might drive such shifts.

Stress has been implicated in causing people to be more reliant on the use of stereotypes. Mindfulness has been shown to reduce stress, in addition to its promise as a method to reduce negative judgments of members from historically disadvantaged groups.

U.S. police departments have attempted to address racial inequities in policing with diversity training. However, little research has evaluated whether these trainings are effective at changing officers' beliefs, motivations, and actions. To examine their efficacy, we tested a day-long implicit-bias-oriented diversity training designed to…

Numerous empirical findings have shown biased judgments of (future) teachers depending on students’ ethnic and social background. Furthermore, research has indicated that (future) teachers’ stereotypes and attitudes differ depending on students’ backgrounds and appear to influence (future) teachers’ judgments. Based on theories of stereotype…

We study whether and to what extent social media information can reduce (ethnic) discrimination in a two-sided market characterized by asymmetric information. We analyze whether information that breaks with prevailing ethnic stereotypes might induce the uninformed side of the market to update its probabilistic beliefs on a desired, but hidden…

Research on persuasion has shown that for attitudes to change people need to take into consideration not only the thoughts message recipients generate in response to proposals but also how people think about their own thoughts (metacognition). In the present research, we introduce a new perspective for improving outgroup attitudes focused on…
