The relevance of scientific knowledge for science and technology policy and regulation has led to a growing debate about the role of values. This article contributes to the clarification of what specific functions cognitive and noncognitive values adopt in knowledge generation and decisions, and what consequences the operation of values has for policy making and regulation. For our analysis, we differentiate between three different types of decision approaches, each of which shows a particular constellation of cognitive and noncognitive values. Our (...) objectives are to present a structured analysis of the varying functions that different kinds of values can adopt, as well as the value-related tensions and trade-offs they give rise to. We argue that the operation of noncognitive values in scientific knowledge generation, policy, and regulatory decision making can be understood as an enabling factor, rather than a limiting one.

El objetivo de este artículo es mostrar no sólo que no hay incompatibilidad entre los factores cognitivos y sociales en el análisis de fenómenos científicos y tecnológicos, sino que se complementan. Esta idea se ejemplifica con el estudio del error humano desde una doble perspectiva: la de un científico cognitivo como James Reason y la de un ingeniero como Henry Petroski. El análisis de catástrofes a causa de fallos en estructuras arquitectónicas o en procesos industriales muestra que sólo teniendo en (...) cuenta sus elementos cognitivos y sociales podemos disminuir los fracasos y aumentar los éxitos de la actividad científico-tecnológica.
