The United States is in the middle of one of the most dramatic crime declines in its history — and almost no one seems to know it. (Unless, of course, you read this newsletter.)
FBI data shows violent crime fell 4.5 percent in 2024, with murder plunging nearly 15 percent. Data from the Council on Criminal Justice suggests homicides dropped another 21 percent in 2025 across major cities, potentially putting the country on track for the lowest murder rate ever recorded.
And yet, the US murder rate is still roughly two-and-a-half times Canada’s and five times higher than most of Western Europe. America still locks up more people per capita than almost any other nation on earth. Compared to other wealthy nations, we still have a serious crime problem — and a criminal justice system that too often fails both victims and offenders.
Jennifer Doleac wants to change that. Doleac is the executive vice president of criminal justice at Arnold Ventures and a member of our inaugural Future Perfect 50 list. Her new book, The Science of Second Chances, makes a data-driven case that small, evidence-based interventions at key points in the criminal justice system can dramatically reduce recidivism — and that we’re leaving an astonishing number of those opportunities on the table.
I talked to Doleac recently about what the research shows. Here are five takeaways.
