Honestly physicists don't actually know what measuring is either. We don't know when exactly the system is considered "measured" in the chain of entanglement, this is called the Measurement Problem.

Answers range from "shut up don't think about it" to "there's an infinite amount of universes split from each other for each quantum event!".

We know how it works, we just don't yet understand what is going on under the hood.

In short, quantum effects can be very obvious with small systems. The effects generally get averaged out over larger systems. A measurement inherently entangled your small system with a much larger system diluting the effect.

The blind spot is that we don't know what a quantum state IS. We know the maths behind it, but not the underlying physics model. It's likely to fall out when we unify quantum mechanics with general relativity, but we've been chipping at that for over 70 years now, with limited success.
