Psychological studies on close relationships have often overlooked cultural diversity, dynamic processes, and potentially universal principles that shape intimate partnerships. To address the limited generalizability of previous research and advance our understanding of romantic love experiences, mate preferences, and physical attractiveness, we conducted a large-scale cross-cultural survey study on these topics. A total of 404 researchers collected data in 45 languages from April to August 2021, involving 117,293 participants from 175 countries. Aside from standard demographic questions, the survey included valuable information on variables relevant to romantic relationships: intimate, passionate, and committed love within romantic relationships, physical-attractiveness enhancing behaviors, gender equality endorsement, collectivistic attitudes, personal history of pathogenic diseases, relationship quality, jealousy, personal involvement in sexual and/or emotional infidelity, relational mobility, mate preferences, and acceptance of sugar relationships. The resulting dataset provides a rich resource for investigating patterns within, and associations across, a broad range of variables relevant to romantic relationships, with extensive opportunities to analyze individual experiences worldwide.
Judgment and Decision Making (JDM), an interdisciplinary field integrating psychology, economics, management, and cognitive science, has provided substantial insights into human decision-making processes over the past 70 years. Despite its rich history, the field’s credibility relies on replication to validate findings across diverse contexts and enhance methodological rigor. This chapter examines the replication landscape within JDM, highlighting key milestones such as the "replication crisis" and major collaborative replication projects. We assess current replication efforts of JDM effects using comprehensive sources, including academic databases and collaborative networks. Our review of over 100 studies (osf.io/j58t2) reveals a 44% success rate in replications, with an additional 25% showing partial replication. Successfully replicated effects often involve well-established paradigms like economic games and numerous heuristics and biases. However, challenges persist in replicating priming effects and other subtle manipulations, such as incidental anchors and research on the unconscious thought advantage. The chapter underscores the importance of transparency practices and collaborative efforts in addressing replication challenges, ultimately aiming to strengthen the integrity of JDM research.

Research on financial well-being (FWB) is experiencing rapid growth despite a lack of internationally validated measures. Most of the literature relies on unidimensional FWB scores calculated as the sum of responses to statements in cross-sectional data from individual countries. We conducted the first Europe-wide longitudinal assessment of two dimensions of FWB and evaluated their measurement invariance. The data were collected in turbulent times (at the time of the COVID-19 pandemic, the beginning of the economic downturn, and the war in Europe) in 12 European countries. Our analysis confirms the FWB’s multidimensionality and its measures’ longitudinal invariance, allowing for cross-wave comparison, while the evidence for cross-country invariance is mixed. We also find that a sense of control and subjective financial knowledge are notable correlates of FWB. However, subjective knowledge is more strongly related to expected future financial security, while the sense of control is related to both dimensions of FWB to different degrees. Our results emphasize the need to distinguish between the components of FWB in appropriate analyses and interventions and to take into account the potentially different structures of FWB in different countries.
