Resumen

El presente artículo revisa el paradigma experimental de contraste de la polarización grupal desde el punto de vista del análisis estadístico, discute e ilustra las serias deficiencias metodológicas del análisis estadístico utilizado comúnmente en la literatura para contrastar el fenómeno de la polarización grupal (pruebas t y ANOVAS) y propone una vía alternativa de análisis para establecer la prevalencia del fenómeno utilizando análisis para datos categóricos. A la luz de la crítica efectuada la evidencia sobre polarización grupal necesita ser reanalizada desde el nuevo enfoque de análisis propuesto.

Abstract

This paper focuses on three points about the methodological fundamentals currently accepted and used in the group polarization experimental paradigm. First, the paradigm is critically revised from a methodological point of view. Second, several deficiencies concerning the parametric tests normally used (t-test, Anova) to verify the group polarization phenomenon are pointed out and illustrated with data examples. Finally, an alternative method based on the categorical data analysis is proposed. This criticism suggests that the group polarization phenomenon should be re-analyzed from a new angle.
