You're presuming the answer having assumed it from your prejudices ...

EXCEPT this was an ACADEMIC study, not a MARKETING study, and as I understand it, the researchers were surprised by the result.
They picked a bunch of large companies with the idea of calculating db spend as a proportion of turnover. No bias there. They plotted those two figures, and were surprised to get a double peak. No bias there, either.
When they investigated this unusual phenomenon, they discovered the lowspending peak was almost entirely Pick-based dbs, the high-spending peak was relational.
I make that Science, not marketing. As for why there aren't any more studies, is it not reasonable to conclude that those studies WERE marketing studies, and got suppressed because they didn't give the wanted result?
