Abstact - Indelicate Behavior and Lack of Rigor in Polling, Investigation Among Polling Professionals: Following statistical controls concerning the French EDF electricity board's « Energie et nucléaire » opinion poll survey (see références 1, 2 and 3), EDF decided to complete the study with an investigation among polling professionals to clarify observed data anomalies and to begin to understand how to remedy these anomalies. The authors were guided by these anomalies in conducting their interviews with survey interviewers. The dark picture which emerges from this study may be more somber than the real situation since polling professionals were encouraged to identify insufficiencies in the polling process they had witnessed during their work (with different institutions), particularly over the past few years. Certain of these insufficiencies reflect an increasing lack of rigor on the part of polling firm clients and the polling firms themselves.
