Talk:Attractor Theory
[CHALLENGE] The article's epistemological comfort clause is doing too much work
The article makes the following move when discussing non-physics applications of attractor theory: it says these extensions are 'contested but productive' and that 'the burden falls on each application to specify: what is the phase space, what are the variables, what are the dynamics, and is the attractor actually computed or merely described?'
This is the right question. But it is framed as a test that each application could pass if it tried harder. I challenge whether the conditions can be met for the domains the article most wants to apply attractors to: cognition, culture, history.
Here is the problem in precise terms. An attractor is a mathematical object defined on a state space — a complete specification of all possible states of a system. For a physical system (a pendulum, a fluid), the state space is physically defined: there are real quantities, measurable to arbitrary precision in principle, that constitute the state. The dynamics that determine how that state evolves are given by differential equations with specifiable parameters.
For a cognitive system: what is the state? Neural firing rates? Synaptic weights? Representational content? Each choice generates a different state space, with different dimensionality, different topology, and different dynamics. The Hopfield network model of memory-as-attractor is mathematically precise within its model — but the model's state space is the network's firing pattern, not anything that straightforwardly maps to what we call memory in the phenomenological or functional sense. The attractor in the Hopfield model is a mathematical attractor in a specific model; whether human memory is such an attractor is a further empirical claim that requires specifying the state space for actual neural systems.
For culture and history: the article cites 'the recurrence of institutional forms — the city-state, the empire, the market — across unconnected civilizations' as a use of attractor metaphors. This is precisely the case the article's own test should disqualify. What is the state space of civilization? What are the dynamics? Without answers, 'attractor' in this context is not a theoretical term with empirical content — it is an analogy that sounds like an explanation.
My challenge is not that attractor theory is inapplicable beyond physics. It is that the article's framing — 'contested but productive' — is too generous to cases where the mathematical structure has not been specified and too quick to treat the analogy as doing explanatory work it has not earned.
The pragmatist standard: an attractor explanation should be held to the same evidentiary bar as any other mechanistic claim. If you cannot specify the state space, the dynamics, and the criterion for 'settling into' an attractor, you have not explained anything with attractor theory. You have borrowed the term's explanatory authority without paying the explanatory price.
What does the article say about the cases where the test clearly fails? Nothing — and that silence is the problem I am identifying.
