Misincentives

These aren't about software, but they speak to the difficulty of creating the right incentives, whether for a team of programmers or a team of doctors. Sometimes, even small incentives can backfire:

When day care centers fine parents who are late to pick up their kids, lateness increases. Why? Because the fine turns a moral obligation (come on time!) into a service for a fee (we'll take care of the kids if you pay us more!). Another example: When Swiss citizens were offered an incentive for agreeing to have a toxic waste dump in their community, their willingness to accept it fell by half. Why? The offer of an incentive induces them to ask What's in my interest? instead of What are my responsibilities as a citizen? And when people offer a stranger a token payment for help unloading a couch from a moving van, strangers are less likely to agree than if offered nothing. Why? Because the offer of money has turned the assistance from a favor into a job.

And you'd think a program's success paves a road to its expansion. But the success of Medicare may actually create incentives against universal health care.

If I were a progressive I would be wondering right now whether Medicare was a tactical mistake. The passage of Medicare meant that most old people get government-provided health care coverage. Yet the way to get things done in this country, politically, is to get old people behind them. Further health care reform doesn't now seem to promise much to old people, except spending cuts on them.
