Abstract: En la literatura sobre determinacion subjetiva de funciones de densidad probabilidad de rendimientos de cultivos, se ha senalado que los agricultores tienden a percibir f.d.p. muy estrechas, un resultado que coincide con el senalado en ortros contextos experimentales. En este trabajo se ha constatdo que investigadores y expertos en produccion vegetal tienen tambien una probre percepcion de la forma de la f.d.p. Esta sesgo en la perception de la f.d.p. sera compartido por agricultores y expertos, estos ultimos con una buena formacion estadistica. Sun embardo ambos grupos realizan in trabajo diario exitoso que implica frecuentemente discriminar entre f.d.p. de rendimientos de cultivos...The literature on the subjective elicitation of crop yield probability density functions points out that farmers have a tendency to perceive very tight PDF, a result which concurs with findings found in other experimental contexts. This study demonstrates that both academic and research experts in plant production have poor perception of what pdf is really like . This bias is shared by farmers and experts alike, the latter with solid statistical background. However, both groups carry out their work every day successfully, despite the fact that it frequently involves the distinction between different crop yield PDF's.
