They reached out to several major publishers and partnered with an anti-piracy outfit, to test whether takedown efforts have a measurable effect on legitimate book sales... While the researchers found a small positive effect in the takedown category, it wasn’t pronounced enough to be statistically significant. Only after the researchers tried a Bayesian analysis, adding data from previous research, did they find an uptick in book sales.

Sounds like fair and unbiased science. \s
