Argument From Ignorance - Distinguishing absence of Evidence From evidence of Absence

Distinguishing absence of Evidence From evidence of Absence

Absence of evidence is a condition in which no valid conclusion can be inferred from the mere absence of detection, normally due to doubt in the detection method. Evidence of absence is the successful variation: a conclusion that relies on specific knowledge in conjunction with negative detection to deduce the absence of something. An example of evidence of absence is checking your pockets for spare change and finding nothing, but being confident that the search would have found it if it was there.
