Funny, I recalled a tool called "molly-guard" which solves the problem when you want to reboot a Unix server, but can be on the wrong one. It asks to type the server name.

Anybody who rebooted a wrong server can say that this tool is brilliant.

Like "--dry-run" but for "reboot."

These kind of obstacles don't work for any action that the user does repeatedly.

Dialogs that pop up and ask "Are you sure you want to delete ...?" -> users just automatically click yes, because they already did that the last 10 times and just want to get on with their work.

Logged in to server "alpha" instead of "delta" because you thought that's the right one. Tool asks you to write the server name. You type "alpha" because you know you're on alpha. Reboots the wrong server.

Github ask you to confirm the repo name before deleting by typing it into a text field. User looks at what the repo name is and types it without thinking. Or, like lazy me, mark and drag the displayed name into the field, so you don't even have to type.

The point is, users already decided to do the action when they started. It's nearly impossible to consistently make them stop and re-evaluate their decision, because that's extremely high friction and annoying. They quickly learn to circumvent the friction as efficiently as possible (i.e. without thinking about it).

A better solution is to just do it, but let the user undo it if it was a mistake (not always possible of course).

After that, it's always "select, copy, paste, confirm" without thinking. I believe the better approach is to practice "Chaos Monkeys" and improve the infrastructure to survive even if someone makes a mistake.

Or, like lazy me, mark and drag the displayed name into the field, so you don't even have to type. Pretty easy to solve this sort of stuff with timers: "Sure, the repo will be deleted in <timer>. Press here to abort: <button>." Or have the timers on the backend and just show the user an undo button.
