Most tropes are obviously either present or absent in a work, and can be added to a work page immediately after the work is released. Others, particularly Audience Reactions, tropes that involve the passage of real-world time, and those that span a large number of installments, can take a little bit to be sure that they apply. See also: Speculative Troping.
The following is a list of tropes and Audience Reactions that, for one reason or another, have a formal, mandatory waiting period before examples may be added to work pages, YMMV pages, or the main trope page.
Even where no formal mandatory waiting period is in place, before adding an example of an Audience Reaction, it's a good rule of thumb to ask oneself: "Will this still be relevant in a year? In a month? In a week?" If the answer is "no" or even, "I'm not sure," maybe hold off a little while and see what happens. Fan reaction can often be knee-jerk. It takes time for fan and critical consensus to form. Controversies that burn brightly often burn out quickly. Attempting to catalog every flash-in-pan Audience Reaction often results in pages that are cluttered and/or overly complain-y.
Note: Entries on this list have been agreed upon by consensus in this thread. Do not add or delete them without first reaching consensus there.
Pages with a mandatory waiting period:
- Base-Breaking Character (6 months after the character is introduced or becomes controversial, whichever comes later): Due to being a magnet for knee-jerk reactions whenever a character is disliked by any portion of the fanbase. Cleanup thread here.
- Broken Base (6 months after release or the issue becomes divisive, whichever comes later): Due to being misused for any disagreement within a fanbase, no matter how minor or short-lived. Cleanup thread here.
- Complete Monster (2 weeks): Due to frequent misuse; the waiting period allows more people to experience the work so that consensus may be reached on newer examples. Cleanup thread here.
- Magnificent Bastard (2 weeks): Due to frequent misuse; the waiting period allows more people to experience the work so that consensus may be reached on newer examples. Cleanup thread here.
- NeverLiveItDown.Real Life (25 years): Due to being a magnet for agenda-based editing. Waiting period implemented so that it can be conclusively shown that the example, in fact, never did live it down.
- NeverLiveItDown.Sports (10 months): Similar to the Real Life section, though it takes much less time to become conclusive.
- Overshadowed by Controversy (6 months): Controversies often burn bright and then flare out, meaning that controversies that seemed important around release time can be forgotten before too long. Cleanup thread here.
- Unintentional Period Piece (10 years or exceptional circumstances): Generally takes at least ten years to determine what the period-piece hallmarks of a given time period are. Cleanup thread here.
- The Woobie (2 weeks): Due to frequent misuse; the waiting period allows for more people to experience the work so that consensus may be reached on newer examples. Cleanup thread here.
