“My experience (belief or assumption), because it seems (IS) so correct, so right, (for me), MUST be the only possible experience, for others, too.” (This is far different from the D-K Effect.)
As in “cables (fuses, etc.) don’t (can’t possibly) make a difference in sound.” And the negative judgements are frequently not based on personal experience. Remember the cartoon strip “There Oughta Be a Law?” 🙃
