It's ALWAYS on those who make an affirmative claim to prove the claim with a plausible theory and valid evidence. Sans a plausible theory and valid evidence, the claim is rightly written off as nonsense.An example of an Appeal to False Authority.
Geoff is making a Texas sharp shooter fallacy. He's claiming that because 90,000 boutique fuses have been sold to happy customers, they must do something, while deliberately ignoring the billions of fuses billions of people use every day quite happily as well. His argument could just as easily be flipped to say "Because billions of common fuses have been sold with overwhelming customer satisfaction, common fuses must be superior". Neither argument is necessarily logical or accurate because both presume sales volume somehow correlates to technical capabilities. It's an idiotic presumption on it's face.An example of Base Rate Fallacy.
