Some approaches involve the production of legally binding advance decisions, which only cover decisions to refuse medical treatment, or the appointment of an attorney. This should be offered to everyone who is at risk of losing capacity (for example through progressive illness), as well as those who have fluctuating capacity (for example through mental illness). Various ways to support decision-making capacity are described in Chapter 3 of the Mental Capacity Act 2005 Code of Practice.Īdvance care planning involves helping people to plan for their future care and support needs, including medical treatment, and therefore to exercise their personal autonomy as far as possible. This may mean helping a person with their memory or communication, helping them understand and weigh up the information relevant to a decision, or helping to reduce their distress. It requires practitioners to understand what is involved in a particular decision, and to understand what aspects of decision-making a person may need support with, and why. It does not involve trying to persuade or coerce a person into making a particular decision, and must be conducted in a non-discriminatory way. Supporting decision-making capacity effectively requires a collaborative and trusting relationship between the practitioner and the person. Principle 2 of the Mental Capacity Act 2005 requires practitioners to help a person make their own decision, before deciding that they are unable to make a decision. 'A person is not to be treated as unable to make a decision unless all practicable steps to help him do so have been taken without success.'

This analogy enables us to relate emergent risk aversion to standard thermophoresis, connecting two apparently unrelated concepts. To delve deeper into the belief dynamics, we liken it to the behavior of an active particle subjected to state-dependent noise. Initially, we observe the rise of dissipative structures in the steady state of the belief space due to time-reversal symmetry breaking at intermediate exploitative levels. Through exploitative, prediction-error-based belief dynamics, the decision maker incurs a cognitive energy cost. We utilize this concept to analyze a two-armed bandit game, a standard decision-making framework under uncertainty, considering exploitation, finite memory, and concurrent allocation to both game options or arms. Using Landauer's principle, which posits that time-irreversible information processing consumes energy, we establish a thermodynamically consistent measure of cognitive energy cost associated with belief dynamics.
