Sep 9, 2026 · 28m

Summary

Tim Harford examines whether early prisoner releases increase recidivism, finding that rising recalls stem from probation service stress rather than new crimes. He debunks claims that UK millionaires are fleeing due to taxes, attributing the drop to inflation and asset prices. The episode also clarifies that while European wildfire coverage is alarming, global and regional data show mixed trends, and it critiques a study overestimating the cost of seagull food theft.
