You don’t have to look too far to find skeptics. It’s our nature to question that which does not fit our worldview.
Take audio equipment fuses for example. I first scoffed at the notion of a fuse impacting sound quality. After all, it’s a half-inch glass tube passing AC power. It’s hard to imagine that tiny object affecting the sound quality of an 80 pound beast like the BHK amplifier. Yet there’s little argument it does (which is why we went some lengths to upgrade our stock fuses).
A skeptic might say “it’s impossible! I cannot believe this has any impact on sound.”
Someone who has just heard the improvement might say, “Hard to imagine how it couldn’t impact sound quality. You’re squeezing hundreds of Watts through a wire no thicker than a whisker.”
The role of skeptic in the grand scheme of things is important. In fact, skeptics are critical to furthering understanding.
If we don’t question what seems wrong, we’ll never understand what is right.
