...nah, just kidding.
Follow Ups:
The excess noise goes up and down in one direction, and down and up in the other.
Oscillates wildly?
When I was in school to learn electronics we had many hands on opportunities to build and test circuits in the lab. When a classmate couldn't get the circuit to work we would say, "No wonder: that resistor is in backwards."
Do you believe that audio grade fuses are directional?
Oh yes i do.

Wherever you go there you are.
the inner foil or outer foil?
I think they were a garage band in a Phoenix suburb in the 80s.
If wire has a direction, why not wirewound resistors?
It's aimless.
Quote from the late Bob Crump.Solid core wire is extremely directional so just mark the end with some masking tape as it comes off the spool. Orient the wires so you have piece of masking tape at either end and terminate the wires. Throw it on a MOBIE or whatever overnight and then listen to it noting which way gives the highest image height. This is the correct orientation.
If you run the signal and return wires in the same direction you will end up with hot spots in the stage, normally at or close to the speakers, low image height and have a gaping hole in the middle of the stage...Keep in mind I am referring to the sound of the stage (reflections) not the individual instruments spread across the stage....Interconnects or speaker wires that have pianos wandering all over the stage normally have their signal and return going in the same direction....

Quote from the late Al Sekela
It is easy to conclude that something does not matter if one sets out to ignore it.
In fact, most if not all audio wire is directional. It is easy to hear the difference. Simply make an unshielded twisted-pair interconnect with both wires in the same original spool direction. Insert it between a preamp and power amp, or in a tape loop, and mute the other channel.Listen to a recording with good treble and midrange, such as a jazz piece with robust female vocal or saxophone, and cymbals. Listen to a few seconds, then mute the amp and swap the cable end-for-end. Listen again. Do this a few times and the direction with more treble harshness and midrange hardness will be apparent. IME, this is the incorrect direction for wire.

Finally, it should be noted that we *do* orient all of our axial-leaded plastic film capacitors. When the capacitor is wound, one of the leads will be connected to the outside conductor and the other lead will be connected to the inside conductor. Orienting the capacitor in the circuit properly makes a difference in the sound quality.It took us a while to figure out how, but we built a machine that allows us to tell which end of the capacitor is which. It is a pain, but we sort every single capacitor and mark it for the correct orientation at each point in the circuit. If we had to *listen* to every capacitor to determine the correct polarity, I don't think anybody could afford to buy our products...

I never worry about wire direction, but I certainly acknowledge that it might matter. I do a lot of building and modifying; if I were to do the work necessary to optimize the directivity of every piece of wire, nothing would ever get done. So, I choose to ignore it. I don't know who are the other authorities you cite, but I have the highest regard for Al Sekala, and I miss the dose of sanity and reason that he often brought to this Asylum and to any other thread to which he contributed. Nice guy, too.
He is talking about capacitors. That is an entirely different kettle of fish. He is describing the fact that even film capacitors are "polar" in the sense that one lead will be attached to the outermost foil and the other to the inside of the foil. The former end should be attached to the low impedance of the two circuit elements that are connected in series by the capacitor. In a bypass application in a PS, the outer lead should be connected to ground. This makes a theoretical difference in noise level, not necessarily sonics. Truthfully, I observe this convention when installing film caps but I have never heard a problem when I did not observe it.

Because they're symmetric.
