 Let's assume that you regularly ride a bicycle on warm summer days. However, on one particular day, your front tire hits a small stick at an awkward angle causing you to fall from your bicycle and break your arm. After your arm is healed, you return to that spot where you fell, and sweep that specific area clear of any small sticks that may have fallen, or been blown by the wind, from nearby trees. Let's assume that you regularly ride a bicycle on warm summer days.

 By incorrectly treating "​Common Cause" variations as "​Special Cause" variations, the result resembles the 1976 arcade game, "​Whac-A-Mole"​ (where moles pop up from their holes at random, and the player earns points by forcing them back into their hole through hitting them directly on the head with a mallet). In the end, nothing is accomplished... but the player has a false sense of accomplishment reflected by their score. By incorrectly treating "​Common Cause" variations as "​Special Cause" variations, the result resembles the 1976 arcade game, "​Whac-A-Mole"​ (where moles pop up from their holes at random, and the player earns points by forcing them back into their hole through hitting them directly on the head with a mallet).

 When radio first appeared, the signal had to be manually adjusted for optimal reception. During the mid-twentieth century, Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), was introduced allowing the radio circuitry to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal. It was primarily used in radio receivers to keep the receiver tuned to the frequency of the desired station. When radio first appeared, the signal had to be manually adjusted for optimal reception.
