A silver bullet is a term which tends to express a straightforward and simple solution to a problem. It has origins in the lore that werewolves could be easily killed with a silver bullet. Earlier, it was thought witches and vampires could be killed with a silver bullet; though the more traditional destruction of witches was burning, and traditionally, both beheading and staking a vampire through the heart is thought to be the means by which one is dispatched.

Some technological developments have been called a silver bullet. For example the discovery of antibiotics, in particular, penicillin is often called a silver bullet. Often the term silver bullet is thought of as the cure all for a problem threatening humanity.

Frequently, the term silver bullet is used to dismiss something as not easily accomplished. For example, consider the statement “Increasing funding to schools is not a silver bullet for improving education.” Often the phrase “not a silver bullet” or “no silver bullet” is more common than something actually being described as a silver bullet.

This is likely because there are few silver bullet solutions in a complex world with complex issues. Most problems require less than straightforward solutions. Thus, for example, some look to cloning human organs as a potential silver bullet for the lack of available organs needed for transplant. This is by no means a silver bullet, because such cloning is still far from perfect and both medical and ethical questions remain.

The silver bullet solution to address an issue is often wishful thinking. In hindsight, even a medication like penicillin has created its own issues. Medical researchers know they now run a race between developing stronger antibiotics and between creating more strongly antibiotic-resistant strains of bacteria by applying stronger antibiotics. So while the silver bullet seems like a splendid concept, it oversimplifies the complexity of any problem.
