This theoretical claim remains untested despite experimental feasibility. [speculation]
This is a claim that should be testable experimentally. To my knowledge it has not been subjected to any tests, although one might draw inferences from some experiments surveyed by John Ledyard (1995).
QUESTION: The untested nature of this claim suggests a gap in the experimental literature worth exploring — what experiments might settle it?
