I'm trying to think of a word or phrase that describes what I assume is a statistical concept. The situation is where one gets angry that an improbable outcome has occurred, using the fact that it is improbable to declare that the outcome should not have happened and therefore they have "bad luck." Specifically, this would be a situation where the causes leading to the outcome are repeated without the person noticing until it causes the improbable outcome. This is probably much more simple than I'm making it, but my brain is mush right now. Example: Every morning, I come into my office and put the key in the door. Nearly every morning, I put in the correct key and the door unlocks. One day, I put in the wrong key on accident, and get angry because this highly improbable event should not have happened, even though my rational mind knows that "improbable" does not mean "impossible." I wonder why it had to happen at this point, and not any other point (since I'm presently experiencing "this point" and not any other), though also knowing this fails to take into account that the sheer amount of times that I perform this action means that at some point, the negative outcome, however improbable, will likely occur. I would take a word, phrase, larger concept...heck, I'll read a book on it if anyone has one in mind. It is directly related to something I'm trying to do at work, so any help is much appreciated. I'm not much of a statistics person, so I'm hoping this will be an easy answer for someone on this site http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif
