Upgrading wall outlets

It sounds better for the same reason that your car drives better after you wash it, for the same reason you're more likely to buy a house if you smell bread being baked in it, and for the same reason your impression of someone is dramatically different depending on whether you happen to have a cold beverage or a hot one in your hand when you meet them. I'm assuming, of course, that the old wall socket will not have been made of a pig snout.

"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.

Bob bundus:"ALL DOUBTING THOMAS'S SOUND THE SAME"

I take it as a compliment to be aligned with Doubting Thomas, but your analogy is nevertheless a particularly felicitous one, since our conflict--friendly, I hope--does appear to pit the religious against the skeptics. My problem with doubting Thomas is that he didn't doubt enough. In any case, though Thomas fingered the wound, I don't intend to finger a upgraded wall socket. Cheers, or Amen, depending.
