This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions problems in science focus on systematic biases. We broaden lens to emphasize idiosyncrasy conscious and unconscious decisions that researchers make during data analysis. coordinated 161 73 research teams observed their as they used same independently test prominent social hypothesis: greater immigration reduces support for policies among public. In this typical case...
This study investigates researcher variability in computational reproduction, an activity for which it is least expected. Eighty-five independent teams attempted numerical replication of results from original policy preferences and immigration. Reproduction were randomly grouped into a ‘transparent group’ receiving code or ‘opaque only method description no code. The transparent group mostly verified (95.7% same sign p -value cutoff), while the opaque had less success (89.3%). Second-decimal...
Authoritarian regimes frequently employ fragmentation to safeguard themselves against coups and reduce the power of military apparatus. This article investigates impact structural coup-proofing in setting a nonviolent popular uprising that threatens regime its survival. It is argued such settings can have unintentional consequences with respect question whether army fulfills orders repression or defects. If security apparatus highly divided, some armed organizations will seize opportunity...
In this article, we study the political use of denial-of-service (DoS) attacks, a particular form cyberattack that disables web services by flooding them with high levels data traffic. We argue websites in nondemocratic regimes should be especially prone to type attack, particularly around focal points such as elections. This is due two mechanisms: governments employ DoS attacks censor regime-threatening information, while at same time, activists tool publicly undermine government’s...
In authoritarian regimes, governments regularly use overt and heavy-handed visual propaganda to effectively signal regime strength deter protests. Can democratic leaders also this so-called hard project strength, or does kind of authoritarian-style messaging potentially backfire because societal norms for leaders’ behavior? Focusing on a rare instance in which outright was used setting, we study how US citizens perceived its by the Trump administration during 2020 Black Lives Matter...

Propaganda plays a key role in maintaining power authoritarian regimes. Previous research finds that overt, crude, and heavy-handed messaging, so-called hard propaganda, can be used to effectively convey government strength deter citizens from joining anti-regime protests relatively stable autocratic regimes like China. Yet, it is unclear if this also true more contested unstable contexts. In these settings, are likely question such messaging prior beliefs of vary widely. We explore the...
The Varieties of Indoctrination (V-Indoc) dataset contains indices and indicators indoctrinationin education media around the world. It is constructed based on an expert survey fielded incollaboration with V-Dem led by ERC-funded project "Democracy under Threat: HowEducation can Save it" (DEMED). that measureindoctrination efforts in across 160 countries from 1945 to 2021. Theindices capture broad dimensions indoctrination such as potential andindoctrination content, while cover topics...
Russia’s invasion of Ukraine is an attack on democracy, human rights, and the international order. While European democracies have supported their war-torn partner, Russia has sought to undermine public support by stopping its gas supply imposing economic costs citizens. In consequence, Europeans find themselves caught between self-interest principles. We present a theoretical argument test how corresponding arguments for against continued backing affect citizens’ using experimental...
Abstract Most authoritarian countries censor the press. As a response, many opposition and independent news outlets have found refuge on Internet. Despite global character of Internet, are vulnerable to censorship in cyberspace. This study investigates Denial-of-Service (DoS) attacks websites Venezuela details how reporting is related DoS an attempt content. For this empirical test, I monitored 19 Venezuelan from November 2017 until June 2018 continuously retrieved their content status codes...
Following the 2011 Arab Spring, autocrats have sought to limit citizens' ability publicize offline protests over social media. In this article, we explore how users adjust these restrictions. To do so, analyse 33 million tweets sent from Egypt during "Day of Anger" in September 2020. We find evidence online tactical evasion a highly repressive context. Compared neutral users, regime opponents are more likely issue calls for using new or dedicated accounts that contain no personal...
Abstract To what degree are news websites in autocracies resilient to online censorship? I explore this question Egypt, which has begun heavily censor recent years, alongside several other autocracies. Relying on a sample of 145 outlets, systematically how blocking affects traffic outlets and their current statuses. Statistical tests show that blocked Egyptian lost average 54–55 per cent global more likely halt activity. Heterogeneity analyses reveal the loss was particularly strong for...
We introduce a global dataset on education policies and systems across modern history (EPSM), which includes measures compulsory education, ideological guidance content of governmental intervention level centralization, teacher training. EPSM covers 157 countries with populations exceeding 1 million people, time series extend from 1789 to the present. The new opens up for studying several questions concerning political control politicized nature systems. In addition describing measures, we...

This paper reports findings from a crowdsourced replication.

In an era of mass migration, social scientists, populist parties and movements raise concerns over the future immigration-destination societies. What impacts does this have on policy solidarity? Comparative cross-national research, relying mostly secondary data, has findings in different directions. There is a threat selective model reporting lack replicability. The heterogeneity countries obscures attempts to clearly define data-generating models. P-hacking HARKing lurk among standard...

Previous research conducted in closed autocracies indicates that government propaganda can deter opposition, shift political attitudes, and influence emotions. Yet the specific mechanisms contextual factors influencing how when it works remain unclear. We theorize power-projecting differently for supporters opponents polarized electoral authoritarian regimes, focusing on emotional reactions downstream effects contentious action. Through two pre-registered surveys Turkey (N=6,286), we find...
Abstract Conventional wisdom expects to see a rise in cyber activities around aggressive foreign policy events. In this article, I test claim by investigating whether sanctions lead an increase denial-of-service (DoS) attacks using new data on DoS measured from Internet traffic. Exploring the development of imposed against Russia 2014 indeed shows several sanction sender states. Extending case study systematic analysis, including all threats and impositions made United States European Union...
