“perceptibility of judgement” is not rigorously defined in these papers, as far as I can tell.

The proposed JTP principle is suspended in midair, too. I can’t identify its ethical basis. Whatever perceptible judgement is supposed to mean, why should it always be transparent? Mechanical systems, such as a physical slot that mounts a sliding door, automatically cause alignment of the force that you use to open that sliding door. Is that “judgement” of the slot perceptible as it corrects my slightly misaligned push? Do I care? No.

I would say that any tool we use responsibly requires that we have a reliable and rich model of the tool in our minds. If we do not have that then we cannot plan and predict what the tool will do. It has nothing to do with “judgements” that the tool makes. Tools don’t make judgements. Tools exhibit behavior.
