Summary The journal Systematic Zoology is studied in order to see what effect factionalism in the taxonomic community had on the refereeing process. Publication patterns in the journal were largely independent of changes in editorship. Although the taxonomic community was subdivided into feuding factions during the period under study, little bias along these lines was discernible in the refereeing process when studied statistically. Several explanations are suggested for the wide-spread impression at the time that bias was pervasive.
