This article is published with open access at Springerlink.com Abstract Although Delphi has come a long way in the development of the method itself, or even in business organisation, it has not been used at all in business ethics. To fill this gap, we have reviewed the literature on the use of Delphi in business, and particularly in the field of business ethics; we have also evidenced the method’ s lack of use in this field, but noted its potential contribution to this research stream. An online survey has been administered to scholars in business ethics that have previously participated in a Delphi survey. The scholars come from nine different countries, and the survey has been held between January 2015 and March-June 2016. The findings show that in the ex- perts’ opinion Delphi is as rigorous, appropriate and useful as any other research method in the field of business ethics, such as focus group, interviews, surveys (online) and case analysis. The Delphi method is assessed anonymously and economically by a group of experts dispersed around the world. Moreover, applying the Delphi method in business ethics could enrich the consensus on limiting the fuzzy area in which ethical business decisions (ethical decision-making) are argued and determined. It is a way of facilitating the search for a solution to the ethical dilemmas delimiting a problem, which is a further advantage of the Delphi technique. Keywords Consensus .

Based on the study by Rest [54], Jones [38] developed the concept of moral intensity, in which one of the six components consists of the social consensus that Bis defined as the degree of social agreement that a pro- posed act is evil (or good)^ [38: 375]. Many papers have subsequently focused on it; however, and follow- ing a review of the empirical literature containing ethi- cal papers and on ethical decision-making conducted by Craft [15], it is confirmed that despite its multiple ben- efits (predicting technological advances, achieving a bet- ter understanding of a subject, and reaching a level of agreement on topics without conclusive information) the Delphi method has not been widely used either to ana- lyse or to identify areas of agreement on ethical busi- ness decisions. Nevertheless, the Delphi method could be useful for research in business ethics, as it is now used in the business area, because of its potential in terms of consensus, feedback, and removing group pres- sure. There are both practical demands, as rigorous methods such as Delphi could be useful for delimiting ethical dilemmas, and Delphi could fill a research lacu- na. To support the possibility of adding value in the field of business ethics, it needs to be considered that the Delphi method generates a range of alternative * Leire San-Jose leire.sanjose@ehu.es Jose Luis Retolaza joseluis.retolaza@deusto.es 1 University of the Basque Country UPV/EHU, Avda.
