(1/2) We need more attention to selection bias in qualitative research. A new study in a top sociology journal examines "how young people experience policing," but it draws only on interviews of youth in an organization devoted to abolishing the police, one that bombards... (2/2) ...its members with abolitionist messages. If you repeatedly expose youth to these messages (a few of the Coalition's social media posts are below), and then ask them how they feel about police, you are going in circles. They're going to tell you what you told them.

(1/6) Because we didn't find racial discrimination, Reviewers thought our findings were wrong and our preregistered hiring experiments were flawed, leading to repeat rejections. Some lessons we learned, as outlined in our Discussion.

(2/6) There is publication bias in the literature of field studies on racial discrimination in hiring, as shown in our Appendix. Discrimination definitely exists. But it seems clear that null and negative findings have been left in the file drawer.

(1/7) How much does this NBER paper by a Harvard economist (@S_Stantcheva) copy Dillman et al. (2014)? Let's look...

(2/7) First, the titles of the sections (and subsections) on designing survey questions are uncomfortably close. Here are some section titles:

(1/7) Whenever I say the evidence for evidence-based crime policies is weaker than we think because of QRPs, someone will say I'm speculating. Here's why I'm not. First, we know that many CJ researchers selectively report experimental outcomes in ways that inflate effect sizes. (2/7) We know that sample size is negatively correlated with effect size in CJ experiments, when it shouldn't be, which is bad news: it suggests that whether studies are being written up depends on results being significant (which requires large effects in small samples).

(1/9) Our new article on police-related fear (with @agrahamphd) shows that Black and White Americans live in different emotional worlds. This thread summarizes our findings.

onlinelibrary.wiley.com/doi/10.1111/17…

Data, code, and preprint available @socarxiv and at: osf.io/tgq9b/ (2/9) Most Black Americans live in fear of the police mistreating them. Few White Americans do so. In fact, the modal responses among Black and White respondents to most of the fear questions are mirror opposites: “very afraid” versus “very unafraid.”

(1/8) Our study on questionable research practices (QRPs) and open science practices (OSPs) is now published in JQC. Data are public, link below is to open access version. This thread summarizes the findings. @socpsychupdate @ceptional @siminevazire

rdcu.be/cvwK5 (2/8) First, we review the evidence on the prevalence of QRPs and OSPs in other disciplines, besides criminology. Unfortunately, QRPs are common in all disciplines where scholars have looked.

(1/5) New preprint examining personal and altruistic fear of the police (with @agrahamphd). Although most Whites are unafraid, most Blacks are more afraid of the police than of crime—58% fear being killed by the police vs. 34% by criminals.

osf.io/preprints/soca… (2/5) Altruistic fear of the police is also much higher among Blacks than Whites. For example, a majority (51%) of Blacks worry “often” or “very often” about their family members being hurt by the police, compared to only 9% of Whites.
