AbstractAdvances in knowledge about personality will be fostered by improved research methods, but corresponding improvements in our theories will be needed also, better methods will not be enough Theory itself can have methodological functions, and some methods provide strong impetus toward greater theoretical clarity and rigor Distinctions between methodological developments in research design, measurement, and analysis need to be maintained, and we badly need more research directed specifically toward improving methodologies Some papers in this volume point quite clearly to the need for all aspects of our research to be better rationalized and deliberate, casual and opportunistic decisions about how to carry out research simply will not do These papers indicate, for example, that the trait vs situation controversy would likely never have occurred had the issues been addressed with greater methodological, and logical, rigor This volume is not complete in its coverage of the potentially useful methods for personality research, and attention should ultimately be devoted to such methods as life histories and case studies and cross‐cultural comparisons In general, however, the papers in this volume offer an opportunity to raise the level of research in personality to a new plane of sophistication and revealingne
