Les Binet · Peter Field · Binet and Field · The Long and the Short of It

Les Binet and Peter Field are the research duo who put the effectiveness of marketing communications on a data footing. Their analyses of hundreds of awarded cases from the IPA Effectiveness Databank produced the discipline's best-known rules of thumb: brand building and activation work differently and need each other, the optimal budget split averages around sixty-forty, and emotional campaigns beat rational ones over the long run. Their work gave marketers a shared, numerical language toward the financial leadership for the first time. The methodological caveat belongs in the record: the databank contains submitted success stories, and averages across cases are context-dependent guides, not laws.
