26/01/2023 – ¿Por qué las mujeres juegan peor al ajedrez de media que los hombres? ¿Y qué podemos hacer para dejar que siga ocurriendo? La respuesta puede estar en un montón de ratones, para los que, en 1963, un investigador llamado Robert Rosenthal diseñó un experimento. Se los entregó a otros investigadores que estaban a su cargo, diciéndoles: los he seleccionado por su diferente capacidad. Un grupo es de ratones listos y otro de ratones menos listos. Se mide el tiempo que invierten estos dos grupos de ratones en escapar de un laberinto. En su artículo, Javier Perea y Teresa Sánchez Chaparro nos explican lo que tiene que ver, en su opinión, lo uno con lo otro. | Dibujo: Nadja Wittmann (ChessBase)
