In 1997, Tony Blair’s government inherited a problem: tuberculosis in cattle was rising, farmers were furious, and nobody agreed on whether badgers were responsible. The solution was to commission a gold-standard randomised control trial — 30 sites across the southwest of England, three conditions, run by an independent scientific group. Proper science. No cutting corners.
Eleven years and £49 million later, the trial produced findings that made things more complicated, not less. Reactive culling of badgers made TB rates worse. Proactive culling helped inside cull zones but increased rates in surrounding areas. Two expert panels reviewed the same data and reached opposite conclusions. And by the time the final report landed, the minister who commissioned the review had left office, the department had been restructured, and the politics had moved somewhere else entirely.
This episode is the first in our three-part series on evaluation in government. It’s not an argument against evidence — it’s an argument for being honest about what evidence can and can’t deliver, and what happens when government treats a long-run trial as a substitute for judgment rather than an input into it.
Also: there are quite a lot of badgers.

While we have tried to be as thorough in our research as busy full time jobs and lives allow, we definitely don’t guarantee that we’ve got all the details right.
