Right. The paper also only takes a few seconds to identify as bullshit: rather than having any claims whatsoever about biology or how the human brain in particular depends on quantum behavior, it just takes the Copenhagen-interpretation concept of "observer" over-literally.

While others may have more credible claims that the brain's operation depends on quantum behavior, my inclination is to be highly skeptical due to the basic nature of biology combined with the bias you cite.
