Claim
Another concept related to Campbell's law emerged in 2006 when UK researchers Rebecca Boden and Debbie Epstein published an analysis of evidence-based policy, a practice espoused by Prime Minister Tony Blair.
Correction

This overstates the 2006 paper's novelty. The phrase and idea of “policy based evidence” were already in published use by 2004, so the concept did not first emerge with Boden and Epstein's 2006 paper.

Full reasoning

The sentence implies that this related concept originated in 2006 with Rebecca Boden and Debbie Epstein's paper. But a BMJ editorial by Michael G. Marmot titled "Evidence based policy or policy based evidence?" was published on April 17, 2004, showing the phrase and concept were already in circulation more than two years earlier.

A separate bibliographic record from ERIC confirms that Boden and Epstein's paper "Managing the Research Imagination? Globalisation and Research in Higher Education" was published in July 2006. That means their paper cannot be the point at which the concept first "emerged."

So the accurate version would be that Boden and Epstein discussed or popularized a related concept in 2006, not that it newly emerged then.
