There is a wide spectrum of levels of consensus and belief, and of the conditions required to achieve them.
For example, a situation may be:
Assumed
When it is “common knowledge,” accepted on a default basis, and no evidence to the contrary has been presented or recognized.
Certain, True or Proven
When evidence is conclusive or compelling.
Believed
In law, when there is a credible and reliable informant who is a witness.
Likely
In law, when the summary of evidence is in favor.
Probable
When at least one item of direct, verifiable evidence exists.
Plausible
When consensus-logic arguments “for” are stronger than those “against”.
Uncertain
When evidence and arguments “for” and “against” seem equally plausible.
Doubted
In law, if the existence of a competing or mutually- exclusive situation is suspected.
Unlikely
In law, when the summary of evidence disfavors it.
Improbable
When direct or indirect, verifiable evidence is missing.
Implausible
When arguments “against” are stronger than those “for,” or where consensus logic cannot ascertain consistency or cause and effect.
Suspected
In law, when not believed, but there is some suggested evidence or argument to support it.
Possible
Where no necessary conditions “for” are violated.
Disbelieved
In law, when a credible and reliable informant is a witness to direct contrary evidence.
Impossible, False or Disproven
When all necessary conditions for belief are violated or disallowed by conclusive evidence.
Not Suspected
Not considered, or there exists some generally-accepted reason to deny it.
