==Etymology==
[[Latin]] corroboratus, past participle of corroborare, from com- + robor-, robur [[strength]]
*Date: [http://www.wikipedia.org/wiki/16th_Century 1529]
==Definition==
*to support with [[evidence]] or [[authority]] : make more [[certain]] - synonyms see [[confirm]]
==Description==
'''Corroborating''' [[evidence]] tends to [[support]] a proposition that is already supported by some [[evidence]]. For example, W, a [[witness]], testifies that she saw X drive his automobile into a green car. Y, another witness, testifies that when he examined X's car later that day he noticed green paint on its fender.

Another type of corroborating [[evidence]] comes from using the [http://en.wikipedia.org/wiki/Baconian_method Baconian method], i.e. the method of [[agreement]], method of [[difference]], and method of concomitant variations.

These are followed in [[experimental]] [[design]]. They were codified by [http://en.wikipedia.org/wiki/Francis_Bacon_(philosopher) Francis Bacon], and [[developed]] further by [http://en.wikipedia.org/wiki/John_Stuart_Mill John Stuart Mill] and consist of controlling several [[variables]] in turn to establish which variables are [[causally]] [[connected]]. These principles are widely used [[intuitively]] in various kinds of [[proofs]], [[demonstrations]] and [[investigations]].

In [[law]], corroboration refers to the requirement in some [[jurisdictions]], such as Scotland, that any [[evidence]] adduced be backed up by at least one other [[source]].
