Curiosity, insight, decision-making, and diverse phenomena can all be accommodated by a single imperative: minimization of expected free energy (resolution of uncertainty).

• Minimising expected free energy specifies the optimal balance between goal-seeking and itinerant novelty-seeking behaviour.claim0.840
  Describes the exploitation-exploration trade-off.
• Agents perceive by minimizing variational free energy to ensure model consistency with past observations and act by minimizing expected free energy to make future sensations consistent with preferences.claim0.832
  Formalization of perception-action cycle integrating inference and decision-making.
• Acting to optimize value and perception are two aspects of exactly the same principle: minimization of free energy.claim0.830
  Foundational claim unifying action and perception within single optimization framework.
• Expected free energy decomposes into risk (exploitation) and ambiguity (exploration) terms, providing optimal balance between goal-seeking and novelty-seeking.claim0.829
  Key insight into structure of decision-making; explains intrinsic motivation and curiosity.
• Minimising expected free energy ensures preferred outcomes are realised, thereby avoiding surprise on average.claim0.828
  How expected free energy links to survival.
• acting to optimize value and perception are two aspects of exactly the same principle; namely the minimisation of a quantity [free energy] that bounds the probability of sensory input, given a particular agent or phenotype.quote0.816
  Concise statement of the free-energy principle's unification of action and perception.
• Any system that exists will appear to minimize free energy and therefore engage in active inference. Furthermore, this apparently inferential or mindful behaviour is (almost) inevitable.concept0.812
  Friston's key assertion resolving the tautology: existence implies free energy minimization, making inference inevitable.
• Any system that exists will appear to minimize free energy and therefore engage in active inference.claim0.811
  The reworked argument that free energy minimization is a corollary of existence, not a prerequisite.
