Desde una perspectiva matricial de la cultura, la autora aborda el estudio de las identidades sociales en su dimensión estética. La presentación dramatúrgica de la persona propuesta por Goffman adquiere un perfil más concreto al enfocar a las identidades a partir de sus procesos de gestación y proyección, pues nunca brotan en el vacío sino a través de matrices que ineludiblemente las conforman. Mandoki explora identidades colectivas religiosas como la cristiana, la musulmana y la judía, así como prácticas familiares, escolares, (...) artísticas y médicas donde la estética opera con todo su poder de seducción, repulsión, cohesión o distinción. Ello implica no sólo que cada sujeto despliega identidades diferentes según las matrices en que se ubique y con cuyos símbolos se identifica, sino que lo realiza por medio de estrategias estéticas que suministran la adherencia efectiva.

The conjunction fallacy is the well-documented empirical finding that subjects sometimes rate a conjunction A&B as more probable than one of its conjuncts, A. Most explanations appeal in some way to the fact that B has a high probability. But Tentori et al. (2013) have recently challenged such approaches, reporting experiments which find that (1) when B is confirmed by relevant evidence despite having low probability, the fallacy is common, and (2) when B has a high probability but has (...) not been confirmed by relevant evidence, the fallacy is less common. They conclude that degree of confirmation, rather than probability, is the central determinant of the conjunction fallacy. In this paper, we address a confound in these experiments: Tentori et al. (2013) failed to control for the fact that their (1)-situations make B conversationally relevant, while their (2)-situations do not. Hence their results are consistent with the hypothesis that con- versationally relevant high probability is an important driver of the conjunction fallacy. Inspired by recent theoretical work that appeals to conversational relevance to explain the conjunction fallacy, we report on two experiments that control for this issue by making B relevant without changing its degree of probability or confirmation. We find that doing so increases the rate of the fallacy in (2)-situations, and leads to comparable fallacy-rates as (1)-situations. This suggests that (non-probabilistic) conversational relevance indeed plays a role in the conjunction fallacy, and paves the way toward further work on the interplay between relevance and confirmation.
