Despite its importance, many studies fail reproducibility tests, leading to what is known as the replication crisis in fields like psychology, medicine, and social sciences. Some key challenges include: Insufficient Data Sharing – Many researchers do not make raw data, code, or methodology openly available, making replication difficult.
