The 'mind control' repetition is starting to sound AJ-ish.
I'd agree there, too. I'm still mystified about how seriously you take a fourth-hand unsourced anecdote, lacking any detail or context, to support the notion of mind control.

I really have a hard time to understand they fell into that trap.

Now that you mention "phase shift changes with the value of the resistor", what would the effect of speaker drivers be on the other end of the cable?

Don't forget the crossover network Unless it was to quote Kef "conjugate load matched" i'd expect the reactance would send the impedance all over the place.

Must admit that they did kind of shoot themselves in the foot by changing the load resistor

Right, but you haven't addressed the last part of my post.
ie. would TG's knowledge that SY designed the test plus the knowledge of SY's opinions on cable sound be a factor, even though SY was not present during the trial?

Its one of the sources of audible cable differences with 'boutique' cables. You can design a cable such that the effect is exaggerated, or possibly suppressed, so there is an audible difference, and naturally one cable will 'sound better'.
And yes, you can also 'steer' which is the one that sounds better.

I can see 'mind control' being a necessity for otherwise impossible correct choices, but why for a null result?
Re: the citation, I couldn't confirm Meyer's anecdote. Most citations deal with cultural and ethnic differences. There was an interesting paper on the connection between self-esteem and performance as affected by immediate feedback in reasoning testing. Telling subjects in a social context they're delusional beforehand isn't covered.

Nor is any other aspect of a DBT.

I would say the cables with lower, more consistent delays should sound better. I would like to see more information on the cables used to compare with my testing.

Possible yes, not so easy if you know what you want though.

Assume a fictional subject capable of scoring correctly to a statistically significant degree in a cable DBT. Is it possible in principle for this subject to intentionally throw the results? Memorize a sequence of coin flips, pseudo-random make up answers on the fly, reverse 30% to drop the correct answers below significance; possible in principle? If so, why not subconsciously?
