Thanks, and I looked at the discussion linked by another poster, as well.
If I understand this correctly, this would be irrelevant for the physical sciences, because the subject of the experiment has no mentation. In addition, the effect of "single blind" experimentation on non-human subjects would be somewhat limited, yes?
Am I right in thinking that this concept is not really applicable to any experimentation that would be relevant to the issue of Darwinian evolution ... or am I on Planet Zongo?
Zongo? Bingo!
