The Gambling Commission (GC) recently lauded its Gambling Survey for Great Britain (GSGB), after it was endorsed by Professor Patrick Sturgis in an independent review. However, that backing is far from comprehensive, even from Sturgis himself.

Sturgis, a professor at the London School of Economics, did label the study “exemplary in all respects”. However, as has been the case in the past with the GC, its tendency to produce unreliable statistics was a noticeable theme for Sturgis, who cast doubt over the accuracy of the GSGB, which is due to be published this summer.

Sturgis said: “Until there is a better understanding of the errors affecting the new survey’s estimates of the prevalence of gambling and gambling harm, policymakers must treat them with due caution, being mindful to the fact there is a non-negligible risk that they substantially overstate the true level of gambling and gambling harm in the population.”
