Is There A Study Showing The Observer Effect Ignoring Conscious Intent?

[Adon]

TL;DR Summary

Is there a study which shows that consciousness does not play a role in the Observer effect?

It's obvious that the Observer Effect can take place without conscious observation, for example with a photon and electron out in the wild, but I'm trying to find a single study which disproves the role of conscious measurement within the observer effect.

An experiment which I think would answer my question is this: the Two Slit Experiment but only one slit is observed while the other is not. If an electron passes through the slit which is not observed is detected as being a wave function but without the double slit interference pattern (since the possibility of the electron having come through the observed slit was eliminated when it was not detected), this would prove that the intent of detection does not play a role in collapsing the wave function, but material observation confirms where the electron is not, thus tightening the wave function. If the electron comes through the unobserved slit as a particle, then the intent of observation must play a role in the observer effect, since the particle would not have reacted with anything but the wave function would have collapsed simply because it "knew" it was being monitored indirectly.

There is no "Observer Effect". It's an urban legend perpetuated by non-technical and oversimplified descriptions of the theory, and you likely have been misled by these.

The double-slit experiment is usually misrepresented in these descriptions. In fact there is no "detected as a particle" versus "detected as a wave function" going on, there is no "wave-particle duality".
The particle-like behavior is that detections happen when a dot appears at a single point on the screen so we say that a particle landed there; and this happens whether there is one slit or two, whether there is a conscious observer or not, whether there are detectors at the slit or not.
When we send many particles through one at a time the dots build up a pattern, more dots in some areas and fewer in others. The wave function determines, by its interactions with whatever slits and detectors are present, what that pattern will look like, that is, what areas on the screen have a high probability of detecting a particle and which have a low probability.

There is no substitute for a real textbook, but if you have any interest in understanding what quantum mechanics really is, you might give Giancarlo Ghirardi's book "Sneaking a look at God's cards" a try.
