I've heard that that is why roundabouts are safer than their alternatives: counterintuitively, they're safer because they're less safe, forcing the user to pay more attention as a result.

Roundabouts are safer. They're safer because they prevent everybody from speeding through the intersection. And, even in case of an accident, no head-on collisions happen in a roundabout.
They're safer specifically for vehicles, as they convert many conflicts that would be t-bones (worst for passengers) into getting rear-ended (maximum crumple zone on both vehicles).
Roundabouts are worse for land use though, which impacts walkability, and the safety story for pedestrians and bike users with them is decidedly not great as well.

The what now? Seriously, what in the world are you talking about? Roundabouts are heaven. They physically force drivers to slow down when approaching or leaving them, creating a safe environment for pedestrians and cyclists.
For example, there's no such thing as "running a red light at full speed" at a roundabout, no speeding up to "make the light", etc.
For cyclists specifically, they're amazing, because they eliminate the deadly left-turns. Every turn is a right turn, which is super safe.

They're much safer for pedestrians than intersections. You're only crossing and dealing with traffic coming from one direction, stopping at a median, and then crossing further over.
Unlike trying to navigate a crosswalk where you have to play guessing games as to which direction some vehicle is going to come at you from while ignoring the lights (people do the stupidest things, and roundabouts are a physical barrier that prevents a bunch of that)

One-lane-roundabouts are very safe. I lived in Hannover (Germany) in the 80s and 90s, they had 2 or 3 lanes in the roundabouts. There were large signs that counted the accidents (200+/year) to raise awareness and during the trade fairs (anybody remembers Cebit?) the number of accidents peaked. Today they are all a lot safer because of a lot of traffic lights.
I thought that the idea of roundabouts was that they lead to slightly more accidents than before, but they are of much lower severity than before (the 90 degree intersections they replace).
Same with driving in the winter. Anecdotally I always observe more accidents when the roads are clear.
