"I am sure a chemist could prove by analysis that there is no significant difference between wines and those who claim the opposite are fooling themselves."- Stanwal
Robert Parker has a working memory of hundreds of wines, and he can identify them in blind tastings, and has done so, thus refuting your hypothetical--and in fact, unlikely--scientist. A moderately skilled oenophile, far below Robert Parker, can at least distinguish wines--if not name them--in blind tastings.
Cable, cord, and socket connoisseurs, on the other hand, reject blind tests, b/c blind tests never show that they hear what they say--and indeed believe--they can hear. That said, some of my best friends are cable freaks.
