In some ways, the quantum world is actually more intuitive to us, and the classical world incomprehensibly alien. Our thoughts and behaviors in some instances appear to be more in-line with a universe that operates according to quantum mechanics (even on a macro scale) than our conventional view of reality in regards to things like determinism, causation, and the like. In some cases this even presents itself as what could be describes as frustratingly strong and unshakeable counterintuitive instinctual subconscious thoughts, where our higher level functioning mind knows those modes of thinking are incompatible with a world that functions according to classical science.

Consider someone getting tested for a serious disease, like cancer or HIV. There is an apprehension to being tested, as if the state of the disease is in a superposition of both being present and absent, and it isn’t until it is measured that it becomes a definite certainty. As such, the disease only becomes “real” upon receiving the results of the test. Classically, our status as diseased or clean has already been determined absolutely; the test simply gives us the information of whether we are sick or not and there is zero reason to avoid taking the test.

Yet, most people will have at least a slight hesitance or apprehension. These feelings and behaviors would appear much more in-line with a world where your body can exist in a super position of sick and healthy. This resolves itself either by either intentionally taking a test and having it collapse into a certainty of either sick or healthy, or by discovering some symptom in the future, which will also cause resolution, but this time with the only possibility (or at least a high probability, in cases where the symptom may be misdiagnosed) of being sick. By taking the test, you are making a slight risk of having the disease become real, but in doing so you ensure at no point in the (immediate) future will the superposition resolve itself into a positive certainty through the presentation of symptoms. To me, at least, this much more accurately describes what is going on in my low-level immediate thinking. This contrasts with my high level conscious rational thinking that I for sure already either have the disease or I don’t, and that being tested simply gives me the information that I am safe, or alerts me and gives me a chance to react early to something I otherwise would not.
