This post continues the discussion of the Scottish Community Engagement Trial (ScotCET). In four posts (you can find them here, here, here, and here) I discussed the apparent failure of implementation over the summer. I concluded that despite the unexpected direction of the findings (i.e., those who received the procedurally just treatment had more negative opinion of the police), the treatment effect appeared to be consistent, was not heterogeneous, and thus it could be actually attributed to the research design.

This is just a quick announcement: with other quant people at Department of Methodology at LSE, we have just started the Quantitative Methods Reading Group. This will be a fortnightly group for PhD students where we can discuss papers on/using advanced quantitative methods from different disciplines in the social sciences. Further details and up-to-date information on the upcoming meetings can be found on the Reading Group’s website.
Should you be interested, please do not hesitate to get in touch, I am happy to add you to the Reading Group’s newsletter.
Being on holiday meant that I have had more time to read the press in the last couple of days. I came across a Guardian/ICM poll which found a shift in public opinion regarding the Brexit bill: compared to April people seem to find a higher EU exit bill more acceptable.

Teaching the ‘Survey Research Methods: From Design to Analysis’ course at LSE’s Summer School – and my bike being stolen – meant that I’ve been commuting a lot by bus, and had plenty of time to read. In the last couple of days I have been reading “Go Home?”, this short and captivating book. Continue reading “Go Home? – Some thoughts”
This final post finishes the discussion of the previous three (you can find them here, here, and here) by looking at treatment effect heterogeneity and design heterogeneity.

This post continues two earlier ones (this one and this one) and assesses the effect consistency across the matched pairs in the ScotCET dataset. Part of the redacted dataset can be downloaded at the bottom of this page which will allow you to carry out the same analysis presented below.

How can one evaluate the veracity of the claim made by MacQueen and Bradford (2017), that the treatment effect emerging from the ScotCET RCT is, in fact, attributable to the experimental design, despite the apparent failure of implementation? For this assessment, one needs to discuss some design features of ScotCET. Continue reading “ScotCET and implementation failure 2. – The design features of ScotCET”
As outlined in my earlier post, one of the key propositions in the procedural justice literature is that – at least in most Western countries – procedural justice has an outsized importance in shaping views regarding the police. Yet, there have been only a few studies that established a causal relationship between police practices and the perception of procedural justice (e.g., Lowrey et al., 2016; Sahin et al., 2016), and none, that has explored its mediating role (although see Mazerolle et al. (2013) who used a path analysis approach – more on this in another post). Thus, in my first paper, I decided to “pry open” the black box of causality, and investigate procedural justice’s causally mediating role.

The papers in my PhD have been inspired by the theory of procedural justice policing. There is a lively debate on how this theory should be formulated which should be discussed in its own post sometime in the future. For now, let’s state that by-and-large my perspective is aligned with how Tom Tyler and Jonathan Jackson have been postulating the theory (e.g. Jackson and Gau 2015; Tyler and Jackson 2013, 2014).
