A set of questionnaires was prepared to compare four elicitation methods: point estimation, interval estimation, membership function exemplification, and pairwise comparison. Technical and nontechnical topics were involved, assuming subjects performed either as measurement instruments or as repositories of knowledge. The advantages, disadvantages, and limitations of each method are discussed on the basis of the evaluation of the answers given by 22 professors and graduate students. The analysis of the results presented herein is extended in Part II, where trends in fuzziness are discussed. Both Parts I and II are oriented toward practical applications.
