Of course you do. Conflict of interest *is* bias. "Any designer with their
ego that tied into their design is precisely why THEY cannot be objective
testers." All you're saying is that they are biased for their own design
and, by definition, cannot be trusted.

So it's OK for Fred and Sally to have their output judged by means other
than external validation, but designers must get their output judged by an
approach you have a personal interest in. As if design doesn't get judged by
the ultimate validators: users.

I mean precisely what I said: you want resources to be siphoned off from
design to design validation, in money and time. Read back what you wrote.

So, after all that mumbo jumbo, you seem to agree that bias and conflict of
interest can be found internally or externally, but that you prefer the
external bias.
