Thus, our findings suggest that the recent pluralization of institutional arrangements of global governance is, in principle, in line with citizens’ appreciation of nonstate actors as providers of critical resources for more effective, accountable, and democratic global governance.

Strikingly, the strength of this effect depends on the degree to which citizens expect #nonstateactors to provide expertise, representation, public interest orientation, transparency, or operational capacity.

We present survey-experimental evidence that citizens in BR, DE, US, and ZA ascribe more #legitimacy to #globalgovernance institutions if learning that #nonstateactors – such as civil society organizations, scientists, business, or citizens directly – have a say in important decisions.

The case study: Twitter communication on the Global Compact #ForMigration. The analysis of engagement patterns suggests that tweets sent by UN Global Communication handles (e.g. @UN) have mostly fueled ideological fragmentation through advocative retweeting, mentioning and (hash)tagging.

The general argument: Advocative IO communication on social media increases resonance among like-minded users, but undermines the credibility of IO communication as a source of trustworthy information across polarized "echo chambers."

Großartige Rede heute; gab der ganzen Veranstaltung die nötige Tiefenschärfe - herzlichen Dank dafür!

Using survey and experimental data from Brazil, Germany, Indonesia & US, we show that: 1. people perceive major IOs as ideological. 2. people think IOs are more legitimate if they perceive these organizations as ideologically more congruent with own orientations.

We develop a new understanding of the conditions under which political ideology affects beliefs in the legitimacy of such IOs. We argue that ideology and legitimacy are linked depending on how IOs are perceived as ideological actors.

Past research expected ideology (such as left-right) to matter for how people think about major international organizations (e.g., @UN, @EU_Commission, @_AfricanUnion, @WHO, @IMF), but provided only mixed evidence – at best.

In a new publication in @IOJournal w/ lisadellmuth.bsky.social jonastallberg.bsky.social we show that political ideology is a more powerful driver of legitimacy in global governance than previously understood.
