I don't think that's a very good analogy. Some say Werner Heisenberg himself
preferred to call his great idea the Principle of Tolerance rather than the
Uncertainty Principle, at any rate it says that you can measure things and the
results you get rise above the noise level and are meaningful, but there is a
limit to the precision you can obtain and we can specify exactly what that
tolerance is. Psi results never rise above the noise level.
Perhaps that is the whole point of psi. To pick out signals imbedded in noise.
Given enough noise, all the notes and timing of Beethoven's "Ode to Joy" are
there, but it took a deaf composer to hear them and commit them to paper.

I have often felt this sentiment with regard to life processes. All the enzymes,
lipids, nucleic acids, water, and other constituents so delicately poised
between the chaos of equilibrium and the stasis of a crystal. Too little order
and you get death; too much order and you get death. Somewhere in between, the
magic of life happens.

Psi could indeed be related to the brains ability to derive semantics from the
flow of Shannon information. You ever wondered how somebody like Helen Keller
could have made any sense of the world at all, let alone become an author of her
caliber? How mind arises from brain is so mysterious that there is plenty of
room for psi in them thar hills. Maybe psi is what happens when nature evolves
prediction machines meant to survive a universe that is, at the most fundamental
levels, inherently and intractably unpredictable.
