In order to conduct controlled and replicable experiments simulating legal trials, we present ForenPsy, the first standardized and open testimonial database in Spanish. We curated nine cases (three for each type of crime: homicide, threats, and burglary), with 14 testimonies each (seven suggesting innocence, seven suggesting guilt), resulting in 126 testimonies. Three hundred participants responded two questions for each testimony: one about whether the testimony suggested innocence or guilt, which showed that the index of agreement between the expected judgment and the actual judgment was .85, and another rating the degree of guilt suggested by each testimony, which yielded significantly lower values for innocence testimonies than for guilt testimonies, thereby showing that the testimonials worked properly. ForenPsy, as well as the standards for testimonies, are available at the OSF, so that it can be used and improved by researchers interested in conducting controlled and replicable experiments simulating judicial environments.
