Roland Fryer is a profile in courage; the Harvard economist follows the data where it leads, no matter the outcome. He studied the impact of paying kids for positive behaviors. He demonstrated how charter school best practices can transform even the worst public schools. And most controversially, he conducted a comprehensive study of police use of force, finding that racial discrimination exists at low levels of force but not in shootings. His colleagues at Harvard pressured him to shelve the study; he received death threats. Learn why he didn't cave and why says he would do it again tomorrow.  Roland is not only a leading public intellectual but also a builder. In 2020, he co-founded Sigma Squared, which uses data science and new AI tools to help employers find the best talent for the job, or as he says, supercharge meritocracy. His goal: bring HR into the AI age and take the hiring process from a well-educated guess to a precise science. Roland's accomplishments are even more impressive considering his upbringing: his father went to prison and his mother walked out. Yet, he fell in love with economics and worked his way through college — including stints at McDonald's and Golden Corral —  to become the youngest tenured black professor in Harvard's history! Roland personifies American optimism, and you'll see why.  Learn more about Roland's research and read his study on charter school best practices here. This is a public episode.
