In my times in the army the ones making mistakes would voluntarely choose to do push-ups as a way to grow more brain cells to help them understand the mistakes made and also the ways to avoid them in the future. Of course, the stupid ones did not come up with the idea themselves, they chose it as a better alternative to filing papers and going to a gulag (there you go, they are capable of some thinking under good motivation, aren't they?). You have no idea the rates of brain gowth it produced. A side effect of muscle growth is also nice.
The ones still thinking about voting for Biden should be offered the opportunity.
