Open science practices in the false memory literature.

In response to the replication crisis in psychology, the scientific community has advocated open science practices to promote transparency and reproducibility. Although existing reviews indicate inconsistent and generally low adoption of open science in psychology, a current-day, detailed analysis is lacking. Recognising the significant impact of false memory research in legal contexts, we conducted a preregistered systematic review to assess the integration of open science practices within this field, analysing 388 publications from 2015 to 2023 (including 15 replications and 3 meta-analyses). Our findings indicated a significant yet varied adoption of open science practices. Most studies (86.86%) adhered to at least one measure, with publication accessibility being the most consistently adopted practice at 73.97%. While data sharing demonstrated the most substantial growth, reaching about 75% by 2023, preregistration and analysis script sharing lagged, with 20-25% adoption in 2023. This review highlights a promising trend towards enhanced research quality, transparency, and reproducibility in false memory research. However, the inconsistent implementation of open science practices may still challenge the verification, replication, and interpretation of research findings. Our study underscores the need for a comprehensive adoption of open science to improve research reliability and validity substantially, fostering trust and credibility in psychology.
