Publicación Blinding and the non-interference assumption in medical and social trials(2012-12-25) Teira Serrano, DavidIn this paper, I am going to present and defend the following claims. First, if the participants are not indifferent regarding treatments, we need to implement a blinding device in every trial in order to ground the Non Interference Assumption. But we cannot take its efficacy for granted: we need to test that the blinding actually controlled for the expectations of the participants and no malign unmasking spoiled the NIA. Precisely because this test is necessary, we can only blind the participants up to a certain point: we cannot deceive them. There is evidence showing that if they suspect they are being deceived, they will deviate from the trial protocol, flawing the outcome.Publicación Milton Friedman, the Statistical Methodologist(2008-05-15) Teira Serrano, DavidIn this paper I study Milton Friedman’s statistical education, paying special attention to the different methodological approaches (Fisher, Neyman and Savage) to which he was exposed. I contend that these statistical procedures involved different views as to the evaluation of statistical predictions. In this light, the thesis defended in Friedman’s 1953 methodological essay appears substantially ungrounded.Publicación On the impartiality of early British clinical trials(2013-06-04) Teira Serrano, DavidDid the impartiality of clinical trials play any role in their acceptance as regulatory standards for the safety and efficacy of drugs? According to the standard account of early British trials in the 1930s and 1940s, their impartiality was just rhetorical: the public demanded fair tests and statistical devices such as randomization created an appearance of neutrality. In fact, the design of the experiment was difficult to understand and the British authorities took advantage of it to promote their own particular interests. I claim that this account is based on a poorly defined concept of experimental fairness (derived from T. Porter’s ideas). I present an alternative approach in which a test would be impartial if it incorporates warrants of non-manipulability. With this concept, I reconstruct the history of British trials showing that they were indeed fair and this fairness played a role in their acceptance as regulatory yardsticks.Publicación Camarada Gustavo Bueno Martínez(2023-01-25) Teira Serrano, DavidBreve presentación de los años de Gustavo Bueno como comisario político de la falange en Salamanca en los años 1950sPublicación Etica o economía : Philippe van Parijs y la renta básica(2003-02-22) Teira Serrano, DavidLa renta básica se nos presenta en la obra de Philippe van Parijs como una propuesta política filosóficamente argumentada, de modo tal que convencerá tanto al teórico de la justicia como al ciudadano que votará su implantación. En este artículo analizamos la argumentación de van Parijs mostrando cómo la efectividad política de sus tesis sólo se sostiene a costa de reducir el debate sobre la renta básica a los términos de su propia concepción de la ética. Ponemos en duda, por nuestra parte, el alcance de esta reducción sobre un doble plano: diluye por completo la dimensión prudencial de toda argumentación política, y no deja más alternativa que la educación sentimental para quienes no se dejen convencer por el equilibrio reflexivo.Publicación Debiasing methods and the acceptability of experimental outcomes(2016-01-01) Teira Serrano, DavidWhy scientists reach an agreement on new experimental methods when there are conflicts of interest about the evidence they yield? I argue that debiasing methods play a crucial role in this consensus, providing a warrant about the impartiality of the outcome regarding the preferences of different parties involved in the experiment. From a contractarian perspective, I contend that an epistemic pre-requisite for scientists to agree on an experimental method is that this latter is neutral regarding their competing interests. I present two medical experiments (on smallpox inoculation and Mesmerism) in which debiasing procedures such as blinding and data tabulation provided warrants of impartiality that made people agree on the experimental design even if they disagreed on the outcome.Publicación Frank Knight y los positivistas(Fondo de Cultura Económica, 2002-03-17) Pradier, Pierre Charles; González Fernández, Wenceslao J.; Teira Serrano, DavidEn este artículo intentaremos precisar en qué sentido fue el primer Knight un antipositivista -veinte años antes de la aparición de la obra de Hutchinson- a partir de un análisis contextualizado de sus argumentos filosóficos y económicos. En primer lugar, intentamos restituir su contexto polémico original a los argumentos de Knight, interpretándolos como parte de controversias que hoy son ya historia. En segundo lugar, tratamos de seguir el curso de estos argumentos desde la economía a la filosofía -y a la inversa, cuando es el caso-, sin incurrir en el anacronismo de considerar al positivismo lógico el único de los positivismos que Knight pudo tener a la vista. En este sentido, nuestro análisis pretende contribuir a una mejor comprensión de lo que significó el positivismo en economía antes de que se asociase en los años 1950 a las tesis de FriedmanPublicación On the limits of cultural relativism as a debiasing method(2021-01-01) Teira Serrano, DavidI analyse cultural relativism as a methodological strategy to correct for ethnocentric biases in anthropological fieldwork. I discuss the format debiasing norms may adopt (rules or standards) depending on whether a discipline has a causal or interpretative outlook. Boas and his school advocated for an interpretative approach to ethnographic fieldwork, in which cultural relativism was implemented as a standard (“Only culturally unbiased reports are admissible”) to be interpreted by expert third parties. Legitimate as it may be as a debiasing method, it does not allow anthropologists to adjudicate their debates on biases in their ethnographic record.Publicación El oráculo gramatical de Agustín García Calvo(1998-11-01) Teira Serrano, DavidLo que queremos mostrar en este ensayo es que la pretendida razón común ejercitada por García Calvo en sus escritos encubre una concepción metafísica muy particular del lenguaje, de la que dimanan sus análisis gramaticales de la Realidad; una concepción que no se defiende sino que se postula oracularmente: lo que hay es lenguaje. A ello sumaremos una breve consideración de las limitaciones de esos análisis, más allá de que se conceda o no la tesis metafísica de partida.Publicación What evidence for a cholera vaccine? Jaime Ferrán’s submissions to the Prix Bréant(2023-01-01) Uzcanga Lacabe, Clara; Teira Serrano, DavidThis article analyses how the French Academy of Sciences assessed Jaime Ferrán’s cholera vaccine submitted for the Prix Bréant in the 1880s. Ferrán, a Spanish independent physician, discovered the treatment in 1884 and tried it on thousands of patients during the cholera outbreak in Valencia the following year. His evaluation sparked a controversy in Spain and abroad on the vaccine’s efficacy. The Bréant jury did not see any evidence for it in Ferrán’s submission, a decision usually interpreted in terms of French scientific nationalism (or simple chauvinism): an outsider from the scientific periphery could not be awarded the Bréant. Drawing on the archival records of the award, we suggest that Ferrán failed instead to provide data that the Academy could consider unbiased, according to the contemporary standards for data presentation. We will illustrate these standards at work in the assessment of another submission from Spain, by Philipp Hauser, who received the Bréant for the thoroughness of his statistical endeavour.
