Full Idea
Where one has five to ten sources of converging evidence, the probability of any particular methodological assumption skewing the results falls considerably.
Gist of Idea
Methodology can't skew results if multiple evidence converges
Source
G Lakoff / M Johnson (Philosophy in the Flesh [1999], 06)
A Reaction
There is multiple evidence from one individual, and then groups of individuals sharing evidence. It is absurd to deny considerable objectivity when lots of evidence converges.
