Resumen
La colaboración de la ciencia abierta
Área de la Ciencia:
- Ciencias Psicológicas
- Investigación de la reproducibilidad
Sus antecedentes:
- Un artículo de 2015 de la Open Science Collaboration (OSC) informó de una baja reproducibilidad en la ciencia psicológica.
- El documento de la OSC intentó replicar 100 estudios publicados anteriormente.
Objetivo del estudio:
- Reevaluar las afirmaciones estadísticas hechas en el documento de la OSC.
- Evaluar la reproducibilidad real de la ciencia psicológica basada en los datos de la OSC.
Principales métodos:
- Reanálisis estadístico de los datos presentados en el documento del OSC.
- Identificación de errores estadísticos específicos en la publicación de la OSC.
Principales resultados:
- El documento del OSC contenía tres errores estadísticos significativos.
- Estos errores invalidan la conclusión de baja reproducibilidad.
- El análisis corregido indica una alta reproducibilidad en la ciencia psicológica.
Conclusiones:
- La conclusión original del OSC sobre la baja reproducibilidad es infundada.
- Los datos disponibles en realidad apoyan una alta reproducibilidad en la ciencia psicológica.
- Los estudios de replicación en psicología demuestran hallazgos sólidos.

01:13Psychology as a Science
4.2K
Psychology, as a scientific discipline, aims to understand the mind and behavior through rigorous and systematic methods. The foundation of psychological research is evidence-based, relying heavily on the scientific method to derive and validate knowledge. This structured approach ensures that findings are reliable, valid, and applicable to broader contexts.

02:40The Scientific Method
67.0K
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Social psychology is a scientific discipline dedicated to understanding how individuals think, feel, and behave in social contexts. Unlike common sense, which relies on anecdotal experiences and intuition, social psychology employs systematic research and empirical methods to ensure objectivity and reliability. This distinction is fundamental in distinguishing scientifically supported findings from mere speculation.Four fundamental scientific values guide a structured approach to research in...

Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

01:37Statistical Significance
23.8K
Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...
