Speculation, as it relates to Resident Evil Wiki, is the addition of information originating from unsubstantiated rumors and theories. Generally, the use of original research is prohibited, although in some circumstances listed below, a synthesis of information may be acceptable.
What is not allowed
Some people may add in unsourced theories and rumors into an article, information that is likely to be false. An example of faux-speculation is the assertion that HUNK stands for "Human Unit: Never Killed." Not only is this unsourced, it is a completely false rumor.
What is allowed
Speculation is only permitted on Resident Evil Wiki if and only if it is supported by various reliable sources. An example of this is the fact that Evolved Lickers were genetically modified from regular Lickers by Umbrella personnel, the only theory explaining their differences in appearance and their appearance in an Umbrella facility.
