An anonymous reader wrote into the Nudge blog with an interesting proposal based on the gambling self-ban programs. What about a self-ban program for guns? he wondered. Or at least a program that makes it more difficult for someone to purchase a gun by possibly requiring an affidavit signed by a nominated friend that the gun would be used for a legitimate purpose, or requiring a longer waiting period for those on the list.
The reader proposed aiming the program at people suffering from depression. The reader mentioned that he had purchased guns on two occasions, but had gotten rid of them before any harm could be done. People with anger management problems or those with children might also be a key audience for the program.
Addendum: Like the gambling self-ban program, this one would be completely voluntary.
