The replication suggested that economic background, rather than willpower, explained the other half. [6] [7] The predictive power of the marshmallow test was challenged in a 2020 study.
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.
In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions. It is a crucial step to test the original claim and confirm or reject the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [ 1 ]
