The theory you are referring to is Murphy's Law, which states that "anything that can go wrong, will go wrong." It is named after Edward A. Murphy Jr., an engineer in the United States Air Force who popularized the concept in the mid-20th century. The sentiment behind Murphy's Law suggests that we should always be prepared for things to not go as planned.
