ITHACA/CHICAGO – Without rigorous research and open inquiry, the breakthroughs that have defined the modern era, saving countless lives and delivering tremendous economic growth, never would have happened. From discovering the laws of physics and the germ theory of disease to developing public policies, scholars have used experimentation to move society forward.

Now, as societies struggle with reviving travel, reopening schools, and workplace safety in the shadow of new COVID-19 variants, social experiments are urgently needed to ensure that we implement policies with a proven record of success.

In doing so, we will be building on a storied tradition.
