This study presents a bibliometric analysis of behavioral finance and investment decision-making research published between 2015 and 2025. We used VOSviewer and bibliometrix in R to apply science mapping techniques and performance indicators to 3,110 Scopus-indexed articles from Q1 and Q2 journals. The findings indicate that behavioral biases, financial crises, fintech, cryptocurrencies, and sustainable finance are the main areas of research. Strong cooperation between Asia, Europe, and North America is demonstrated by international co-authorship networks. The results demonstrate how traditional behavioral theories have come together as well as how new topics like digital assets, ESG investing, and pandemic-driven financial behavior are becoming more prevalent. This mapping indicates understudied areas for further research and provides an organized summary of the field's development.
