A recently published, peer-reviewed paper, “A Literature Review and Meta-Analysis of the Effects of Lockdowns on COVID-19 Mortality,” by Jonas Herby, Lars Jonung, and Steve H. Hanke, Studies in Applied Economics, January 2022, concludes: “While this meta-analysis concludes that lockdowns have had little to no public health effects, they have imposed enormous economic and social costs where they have been adopted. In consequence, lockdown policies are ill-founded and should be rejected as a pandemic policy instrument.”
One qualification should be made, and there have been no positive public health effects, but there have been considerable negative ones, such as additional suicides, and people dying from non-Covid diseases such as cancer, because the manic hospitals have semi-closed their doors.
“A Literature Review and Meta-Analysis of the Effects of Lockdowns on COVID-19 Mortality,” by Jonas Herby, Lars Jonung, and Steve H. Hanke Studies in Applied Economics, January 2022:
Abstract: This systematic review and meta-analysis are designed to determine whether there is empirical evidence to support the belief that “lockdowns” reduce COVID-19 mortality. Lockdowns are defined as the imposition of at least one compulsory, non-pharmaceutical intervention (NPI). NPIs are any government mandate that directly restrict peoples’ possibilities, such as policies that limit internal movement, close schools and businesses, and ban international travel. This study employed a systematic search and screening procedure in which 18,590 studies are identified that could potentially address the belief posed. After three levels of screening, 34 studies ultimately qualified. Of those 34 eligible studies, 24 qualified for inclusion in the meta-analysis. They were separated into three groups: lockdown stringency index studies, shelter-in-placeorder (SIPO) studies, and specific NPI studies. An analysis of each of these three groups support the conclusion that lockdowns have had little to no effect on COVID-19 mortality. More specifically, stringency index studies find that lockdowns in Europe and the United States only reduced COVID-19 mortality by 0.2% on average. SIPOs were also ineffective, only reducing COVID-19 mortality by 2.9% on average. Specific NPI studies also find no broad-based evidence of noticeable effects on COVID-19 mortality. While this meta-analysis concludes that lockdowns have had little to no public health effects, they have imposed enormous economic and social costs where they have been adopted. In consequence, lockdown policies are ill-founded and should be rejected as a pandemic policy instrument.”
