Influences of Experts' Personal Experiences in Fuzzy Logic Modeling of Atlantic Salmon Habitat
Abstract The knowledge of scientific experts, which is regularly used in modeling, is acquired by training, education, and practical experiences that modify the experts' perceptions. Using a case study dealing with fish habitat modeling, we investigated the possible influences and potential bia...

A divergence in the confidence intervals (i.e., no overlap) indicated a significant influence of the tested experience.
