Social identity correlates of social media engagement before and after the 2022 Russian invasion of Ukraine.

Despite the global presence of social media platforms, the reasons why people like and share content are still poorly understood. We investigate how group identity mentions and expressions of ingroup solidarity and outgroup hostility in posts correlate with engagement on Ukrainian social media (i.e., shares, likes, and other reactions) before and after the 2022 Russian invasion of Ukraine. We use a dataset of 1.6 million posts from Ukrainian news source pages on Facebook and Twitter (currently X) and a geolocated sample of 149 thousand Ukrainian tweets. Before the 2022 Russian invasion, we observe that outgroup mentions in posts from news source pages are generally more strongly associated with engagement than negative, positive, and moral-emotional language. After the invasion, social identity mentions become less strongly associated with engagement. Moreover, post-invasion ingroup solidarity posts are strongly related to engagement, whereas posts expressing outgroup hostility show smaller associations. This is the case for both news and non-news social media data. Our correlational results suggest that signaling solidarity with one's ingroup online is associated with more engagement than negativity about outgroups during intense periods of intergroup conflicts, at least in the context of the Russian-Ukrainian war.

Addressing climate change with behavioral science: A global intervention tournament in 63 countries.

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

The International Climate Psychology Collaboration: Climate change-related data collected from 63 countries.

Climate change is currently one of humanity's greatest threats. To help scholars understand the psychology of climate change, we conducted an online quasi-experimental survey on 59,508 participants from 63 countries (collected between July 2022 and July 2023). In a between-subjects design, we tested 11 interventions designed to promote climate change mitigation across four outcomes: climate change belief, support for climate policies, willingness to share information on social media, and performance on an effortful pro-environmental behavioural task. Participants also reported their demographic information (e.g., age, gender) and several other independent variables (e.g., political orientation, perceptions about the scientific consensus). In the no-intervention control group, we also measured important additional variables, such as environmentalist identity and trust in climate science. We report the collaboration procedure, study design, raw and cleaned data, all survey materials, relevant analysis scripts, and data visualisations. This dataset can be used to further the understanding of psychological, demographic, and national-level factors related to individual-level climate action and how these differ across countries.

Gender Gap in Urban Job Market During the Pandemic: The Case of Ukraine.

Remarkable resistance of Ukraine has become in the world focus starting from the dawn of February 24th, 2022. While policymakers draft plans to address the consequences of the war, it is crucial to understand the pre-war labor market context, risks of joblessness, inequalities, and sources of resilience. In this paper, we study inequality in job market outcomes in 2020-2021 during another global disaster-the COVID-19 epidemic. While there is a growing literature on worsening gender gap for developed countries, not much is known about the situation in transition countries. We fill in this gap in the literature by using novel panel data from Ukraine, which enacted strict quarantine policies early on. Our pooled and random effects models consistently indicate no gender gap in the probability of not working, fearing to lose job or having savings for less than one month. This interesting result of non-deteriorating gender gap can potentially be explained by higher chances of urban Ukrainian women to switch to telecommuting compared to men. Although our findings are limited to urban households only, they provide important early evidence on the effects of gender on job market outcomes, expectations, and financial security.

Differentiable characteristics of Telegram mediums during protests in Belarus 2020.

Online activism has been pivotal for anti-government protests all around the world. A lot of existing research studies how people use social media to mobilize and coordinate protests. However, some platforms offer more than one kind of medium for communication, in particular, Telegram. We found that a lot of research literature focuses on either one or another medium or sometimes merges them together. In this research, we performed a comparative analysis of three communication mediums in this platform: channels, groups, and local chats during protests in Belarus in 2020. We first collected a dataset which follows six months of protest, which allows us to study the temporal variation of online activism. We find that in Telegram, these three modes of communication are not equally important. Furthermore, they are responsible for different types of communication. For example, in groups, people discuss significant protests that occurred nationwide. In comparison, people discuss local and small demonstrations and protests in chats. Finally, Telegram channels are very distinct from local chats and channels in terms of content. Our finding suggests that future research should consider these modes of the communication independently rather than blending them.

The globalizability of temporal discounting.

Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these reflect true differences in choice patterns between income groups. We tested temporal discounting and five intertemporal choice anomalies using local currencies and value standards in 61 countries (N = 13,629). Across a diverse sample, we found consistent, robust rates of choice anomalies. Lower-income groups were not significantly different, but economic inequality and broader financial circumstances were clearly correlated with population choice patterns.
