Compression Is Intelligence: The Common Ground of Positive Subjectivity and Negative Subjectivity

Why can both positive subjectivity and negative subjectivity be called "intelligence"? This paper's answer: they are both "effective compression"—capturing the regularities of the external world with more concise internal models. But "effective" has two paths: epiplexity maximization as the dominant direction (retaining only structure, compressing into an "I"), and cross-entropy minimization (embracing everything, compressing into a "probability distribution"). The two paths share an essence but employ radically different strategies—they are different positions on a continuum, not opposing poles.
