Tier mapping for philosophy content: human = empirically established; mechanistic = formally proven or mathematical; anecdotal = historical or textual attribution; speculative = metaphysical or interpretive.\n- Cite real sources only: primary works, papers, books, with exact quotes where verifiable.

Gershman published the paper in 2019. The work deconstructs the free energy principle (FEP). It identifies what FEP claims under different assumptions.\\n\\nThe paper shows that unrestricted FEP reduces to exact Bayesian inference. Restricted versions produce predictive coding or active inference. These differ from information gain or utility maximization in specific cases.\\n\\n## Exact Primary Works and Passages\\n\\nGershman, Samuel J. 2019. “What Does the Free Energy Principle Tell Us about the Brain?” Neurons, Behavior, Data Analysis, and Theory 2 (3): 1–10. Also arXiv:1901.07945.\\n\\nKey passage from introduction: “The free energy principle (FEP) states, in a nutshell, that the brain seeks to minimize surprise [1].”\\n\\nFrom section 3: “Thus, if p(s|o) is contained in the variational family Q, then the solution of the optimization problem yields the exact posterior: q(s) = p(s|o). This holds true when the variational family is unrestricted.”\\n\\nFrom conclusions on active inference: “In the active setting (observations can be influenced by actions), active inference is equivalent to an information gain policy when the approximate posterior is exact and the observations are deterministic functions of actions. When observations are stochastic, active inference induces a form of risk-aversion not found in the information gain policy.”\\n\\nFrom section on utilities: “When utilities are interpreted as probabilities, FEP corresponds to a form of planning as inference... The predictions of FEP are distinguished from utility maximization when the utilities don’t correspond exactly to probabilities.”\\n\\n## Convergence Patterns Evidenced\\n\\nThe work touches energy minimization as inference. This aligns with GRAIN patterns of energy flows producing structure and memory.
