Los problemas de validez en el análisis de redes sociales: algunas reflexiones integradoras Jorge E. Miceli Política Validez etapas investigativas consistencia deductiva decisiones metodológicas representatividad de los datos El análisis de redes sociales ha venido para quedarse hace tiempo en las cienciassociales. Sin embargo, la tendencia a considerarlo como un repertorio casi infaliblede instrumentos de análisis es aún una tentación para sus practicantes y tambiénpara quienes no lo frecuentan pero ven en él una especie de quimera capaz deresponder cualquier pregunta teórica relevante. A tono con estas reflexiones,presentaremos una división más o menos típica de las diferentes etapas quedistinguen a una investigación de ARS para intentar dilucidar, en ellas, algunas delas problemáticas y decisiones metodológicas que pueden afectar seriamente lavalidez de los datos, cálculos e inferencias realizadas. Más allá de la especificidadtécnica de las cuestiones que reseñaremos respecto al ARS, nos anima el objetivomás general de analizar sus peculiaridades bajo la perspectiva de cualquier procesoinvestigativo que tenga en cuenta premisas clásicas de la adquisición científica deconocimiento: integridad, pertinencia y representatividad de los datos, adecuacióny alcance de las hipótesis manejadas, nivel de generalidad y consistencia deductivade las conclusiones obtenidas, e incluso la factibilidad de generar modificaciones enel propio objeto de estudio con el fin de producir cambios ajustados a undeterminado diseño de intervención. 2008 artículo científico 1579-0185 https://www.redalyc.org/articulo.oa?id=93101401 es http://www.redalyc.org/revista.oa?id=931 Redes.
