Your team cites "the research" to defend a major decision, and you must decide how much weight it deserves. Findings about pricing and consumer behavior explain more than findings about research methods or new product development. Which findings can you act on as they stand, and which need a local test first?
Marketing research findings are about as strong as psychology's.
Data chart
Average strength of the link between what studies tested and the outcome measured, pooled within each research field, from 0 (no link) to 1 (perfect link).
Marketing findings are about as strong as findings in earlier reviews of psychological, educational and behavioral treatments and social psychology.
Marketing's .24 is rounded from .236 across 176 research reviews with more than 7,500 studies (1918-2012). The comparison values, .24 for treatments and .21 for social psychology, come from earlier research reviews cited in the Discussion (p. 36).
Data chart
Share of the variation in the measured outcome that each area's research accounts for, in percent.
Findings about pricing and consumer behavior explain more outcome variation than findings about research methods or new product development, so judge research by subject area.
Table 5 (p. 32), averages within eight marketing research areas; the dashed line is the all-marketing average. Exact percentages: pricing 13.032%, consumer behavior 8.069%, strategy 6.128%, channels 5.657%, sales 5.219%, advertising 4.640%, new product development 4.111%, research methods 2.372%; overall 5.560%.
Key takeaway
Marketing leaders can use relevant research findings to make marketing's case inside the firm.
The studies span 1918-2012 across eight areas and measure how strong findings are, not financial returns or measured success rates in any market. Large effects may reflect simple questions, and immediate measures may miss lasting new product effects and advertising's carryover, the effect that lasts after the spend stops.
