Given the word "measurement," which sounds like something done by a conscious observer, it's not absurd to posit that somehow conscious observation is involved. And indeed that was posited, most famously by Eugene Wigner. (3/n) en.wikipedia.org/wiki/Von_Neu...

Suppose it’s unconscious observation. Would the collapse change in such a case? I think ‘consciousness’ can be biologically present when the wakeful mind is not aware — as in the daily lives of our digestive systems. Perhaps more clarity is needed with that term before moving on.

Unfortunately this is hardly more clear. Fortunately, people started developing purely physical, mechanistic theories that successfully account for the apparent "collapse of the wave function" under measurement. These include Many-Worlds, pilot waves, objective collapse, and more. (4/n)
