One of the worst intellectual vices of the 20th-c was the promiscuous
transference of "scientific" notions to other fields. Measurement
(though not the unit of mesurement) is of course utterly unrelated to
the consciousness of the measurer. In quantum mechanics it is not the
scientist who affects the results; its the equipment. The scientist has
no effect on what he/she measurs or observes. What Einstein called
"spooky action at a distance" is not in the least affected by the the
human observer observing it. The equipment not the observer affects it.
If you w ant to think about observer affecting the observed, the
relevant field is not physics but social relations. For example, poll
results can affect public opinion.
And incidentally the "uncertainty" principle goes back to the
philosophical thought of the first decade of the 20th century.
Heisenberg merely provided a convenient metaphor for a tendency of
thought already well-developed when he made his discovery in physics.
