Description
Control F is a podcast about data — hard, fuzzy, surprising, and sometimes unreliable data — and all the ways it influences our daily lives. In each episode, we dig deep on a topic and search through research, algorithms, and assumptions to bring you insights on how stuff works. In a world ruled by numbers, Control F reads between the (spreadsheet) lines to find the bigger story.

We dig into the data around surveillance cameras, like CCTV and Flock automatic license plate readers, and talk about whether they prevent crime and make you safer. An earlier version of this episode incorrectly stated that Flock makes license plate readers for police cars. It has been amended to state that Flock makes stationary cameras, and to more clearly explain a law that has restricted mobile plate readers in police cars.

On November 1, daylight saving time ends in the United States. That means most of us will “fall back” to standard time for the following four months. But many states want to stop this twice-yearly clock change and instead stay on daylight saving time all year. One question is at the center of this proposed change: What would permanent daylight saving time do to our health? Clare interviews Dr. Katie Sharkey, professor at the Wake Forest University School of Medicine, to find out – digging into the data on time changes, the body clock, and how proposed changes to the time system could affect our well-being.
