First, we split the universe into quantum object, observer or apparatus, and environment. Then we adopt the frog perspective for the apparatus or observer, implying he, she, or it is ignorant about the exact state of the environment. This implies that—from his, her, or its perspective, quantum superpositions (such as a particle residing in different places at the same time) are suppressed, and the observed quantum object is perceived in a well-defined state having, for example, a specific location.
