RE: Blind testing, like any testing, is not foolproof. Nt
Posted by hahax@verizon.net on November 8, 2016 at 12:14:43:
Really the main difference double blind can reveal is whether a difference is perceived or not. Then you can do many blind tests and ask many observers simple questions related to what you are trying to get at. That involves taste to a degree. It helps then if those results can be correlated to measured tests. That's one of the positive facets of Floyd Toole's tests. They are both double blind tests and correlated to measurements and for what it's worth he believes he can be over 95% sure of a good speaker's performance from the measurements he does that were correlated to double blind tests.
