This week, new Invisibilia co-host Hanna Rosin and Alix Spiegel talk to oil workers in the deep south who tried a social experiment to transform the entrenched macho culture of an oil rig in the Gulf of Mexico. In the process of this shift, they massively improved the safety and productivity of the rig, and also transformed the notion of what a Southern oil man is like.

Our second story involves a grand experiment in shifting a social norm, this time of an entire nation. In the 1990's McDonald's decided to open the first ever McDonald's in Moscow, but were impeded by the social norms around smiling and customer service in Russia. In this story Alix follows the story of Yuri, one of the first McDonald's employees, as he comes to unlearn what his teachers in school taught him: that people who smile at strangers are idiots.

This week, Shots explains how macho oil rig workers got in touch with their softer sides, and how that made the oil rig a safer place to be. You'll get to see Tommy Chreene on his farm in Kaplan, Louisiana. Co-host Hanna Rosin asks if social norms have changed enough so that boys are no longer afraid to cry.
