WHAT THE TOP TIER GETS RIGHT
Methodology as culture. Top scorers publish methodology notes on every study. AAPOR, ISO 20252, and ESOMAR 28 standards are operational, not aspirational.
Sample is infrastructure. Top firms own or co-own probability-based panels. Panel hygiene (response-rate monitoring, composition drift, incentive design) is treated as an engineering discipline.
Analytics is embedded. Segmentation, MMM, predictive modelling, and attribution are delivered alongside fieldwork. Separating "research" from "analytics" is a 2010s artefact.
Continuous over project. Leaders have moved the bulk of their business to continuous tracking and syndicated programs, not one-off projects. The commercial model shift mirrors the client behavioural shift.

HOW WE EVALUATED THIS
Public evidence only: firm websites, published methodology notes, AAPOR/ESOMAR/CRIC membership disclosures, analyst coverage, case studies, and LinkedIn presence.
Three NUUN Digital research-practice leads scored independently. NUUN's own score run by two external reviewers under NDA.
Equal weighting. Ties broken by published US methodology evidence.
Limitations: Consulting firms with research practices (McKinsey Global Institute, BCG Bruce Henderson Institute) are out of scope — they are strategy firms using research instrumentally, not dedicated research houses. Specialist healthcare research firms (ZS Associates, Syneos Health Insights) are out of scope and deserve their own ranking.
Refresh cadence: Annually every April.
