Short 🧵 re: WP w/ @ryan_brutger @jkertzer @dustintingley @jrenshon:

TLDR: we design & test a framework to guide experimenters design choices around 3 elements of abstraction in vignettes:
🔸Hypotheticality
🔸Actor Identity
🔸Contextual Detail
Link: rb.gy/tru8uo Bottom Line:
Most design choices around abstraction in experimental vignettes are less consequential than social scientists often expect. However, adding context into vignettes can attenuate ATEs, and invoking salient real world actor can amplify ATEs.

Short 🧵 on my new working paper:

▪️Main Point: Information about minority representation in healthcare institutions reduces prejudice & promotes preferences for political inclusion (Evidence from 🇮🇱 &🇺🇸)

▪️Link: preprints.apsanet.org/engage/apsa/ar…

Abstract Attached Image ▪️Context: In the 1st wave of #COVIDー19 many discussed the role of Arab docs in 🇮🇱 healthcare (e.g. this 🔥 campaign rb.gy/vsohnn, h/t @shirnosa)
▪️Building on my wp on *contact* w docs (rb.gy/udbpuk) I set out to test how *info* abt Arab docs fx prejudice

I’ve been wanting to write sth abt @PeterBeinart piece re:🇮🇱/🇵🇸

I think that the 1/2 state debate overemphasizes broad pol arrangements over ppl, their immediate enviornments, and behaviors.

Regardless of 1/2 state, Jews and Palstinins will continue living sidebyside 1/n In this @POMEPS piece I try to provide an intuition abt how we can make the reality of sidebyside living more peaceful. To do so, I discuss social science research on segregation, integration, and intergroup relations. 2/n

🚨New WP with the amazing Lotem Bassan-Nygate🚨

Focusing on Israel we demonstrate that electoral competition ↗️ affective polarization, while cross-party cooperation ↘️ polarization.

Short 🧵: Image *Framework*

Competitive elex are a crucial component of democracy. However, building on SIT we expect them to ↗️ affective polarization. Therefore, we consider an institutional remedy for election driven polarization: cross-party cooperation in the form of unity government.

Headed to #APSA2019 and Interested in conflict, prejudice reduction, and field-experiments in MENA? Join us on Thursday, 2:00pm at Hilton (Jefferson West). @aasiegel @salma_mousa_ @David_Romney and I will present our papers, @zeitzoff will discuss, and Donald Green will chair. Image I enjoyed reading the other papers on my panel a lot, and I learnt so much from their creative takes on conflict, prejudice reduction and experimental design. So here are very brief summaries of the paper on the panel:
