Researchers conducted a randomized evaluation among households in rural Burkina Faso to examine whether countries in sub-Saharan Africa are experiencing a slower shift in fertility levels due to lack of access to contraception or households wanting large families. Providing married women with access to free contraception did not reduce birth rates, even when it was paired with information to correct misconceptions about child mortality or village meetings or an edutainment film aimed at ensuring exposure to a diversity of views about family size and modern contraception.

Researchers conducted a randomized evaluation to study if Democratic climate advocates recruit others for climate advocacy and whether they reach out across party lines to increase bi-partisan support. While Democrats were motivated to mobilize others to email Congress on climate action, they were more likely to do so when they believed their efforts would influence like-minded, Democratic-leaning individuals.
