4Question
- How can ACE increase the predictive power of its
models by incorporating the salient features of
actual human decision-making?
5Approach
FIELDS INVOLVED DESCRIPTION -
Neurophenomenology - Cognitive scrutiny of
human experience. - Piercian Semiotics -
INTERPRETANT as a modification of
consciousness that is itself an experience.
- Embodied experiences (Distinctions). -
Capabilities Approach - Liberty instead of
utility. - Embodied distinctions
(Choices).
Experiences ? Distinctions ? Choices
- EVOLUTION - Solves MENOS Dilemma
(Animates Knowledge). -
Variation/Selection/Retention.
6Embodying experiences EDGE Model of inner world
construction
Background embexp1,, embexpi where i is
the total number of experiences an individual has
embodied. Interpretant embexp1,, embexpj
Any subset of embodied experiences belonging to
Background set.
There are many other interpretants influencing
the constitutions of interpretants
7SoWhy should the nature of knowledge be
evolutionary?
- How does evolution resolve Meno's dilemma?
- Because during knowledge acquisition the
individual is getting increasingly familiarized
with an interpretant that lived in a pool of
potentiality and that was finally selected for to
constitute an alternative subset, and provide the
individual with a new (more adequate)
perspective! - Knowledge emerges out of a neuro-phenomenological
evolutionary process that is evolutionary at
every single stage, which is why it may be
simulated using Genetic Algorithms.
8Computational ImplementationGenetic Algorithms
(GA)
Artificial Interpretative Devices (AID)
GA MISINTERPRETING DISRUPTING AID
INCORPORATING CHANCE EEFECTS
9Computational ImplementationIssues of applying
model
- Detailed specifications of each AID (i.e. changes
in initial conditions) - Interaction mechanisms between AID in an agent
- Interaction mechanisms between agents
- Groupings of agents, and the interaction
mechanisms between groupings
- Very difficult to find the detailed
specifications of the decisionmaking process! - If found, access would be limited
10AndWhere do we go from here?
- Change focus from examining regularities to
scrutinizing exceptions (because these may lead
to innovative changes in the system) - Manage unpredictability by
- Unrestricting the possibilities!
- Real politiks of modeling.
11Key question in social-computational terms
- How should variety generating mechanisms, or the
process of generating new variety (variation) be
managed or handled?
12Revisiting suggestions made here at UCS 2005
- Medicine Timothy Buchman
- Interventions that follow regular patterns (i.e.
provision of oxygen) inhibit patient recovery. - Mathematics Bruce West
- Fractal correlations between heart rates.
- Psychology Daniel Miller
- Crises management by moving away from
homeostasis.
13Suggestion from socio-economic systems modeling
seems to be the similar
- When variation alludes to the process of
generating new and alternative variety (i.e. in
terms of possible states of a system). - And variety refers to a measurement of complexity
that directly relates to the number of possible
system states. - Variation may be managed by providing additional
variety.
14Real Life ApplicationEvolutionary Institutions

DYNAMIC EQUILIBRIUM OF KNOWLEDGE
DEMOCRACY MARKETS
15Additional socio-economic justifications for
variety
- Ethics Heinz von Foerster
- In-principle un-decidable questions
- Capabilities Amartya Sen
- Human Development as augmenting peoples choices
- Organizational Theory of the Firm Malerba
- Increasing experience generates more
variability, which can act as source of
creativity and innovation.
16Conclusions
- The field of economics is changing for the
better. - Inner world reconstruction and the emergence of
knowledge may be modeled through an evolutionary
neurophenomenological process. - When agent-based modelling incorporates the
salient features of human decision-making,
detailed access to the computational process is
hindered. - Institutions can advance the evolutionary
dynamics of experiences, distinctions and
choices. - Variation ought to be handled by increasing the
available variety.
17FUTURE WORK
- Find work (JOB).
- Perform computational implementations.
- Develop experimental applications and find
evidence at the organizational level (i.e.
Implications for Knowledge Management in firms).
