SUMMARY
Why natural scientists/professionals and human scientists/professionals are reasoning so differently?
• A frame for interpretation
• Differences explained
An example: physics of the city and cognitive city
• Econophysics and psychological economy. What are they?
• Antithesis and recomposition.
WARNING!
For sake of clarity, in the following slides
I go to the extremes
in describing epistemological, methodological … positions,
BUT
all of us know that
in the real world
scientists and professionals have not so schematic minds
To begin: A closer look to knowledge nature
Conscious knowledge
Whole knowledge
Inconscious use *
Conscioususe *
* of own knowledge type

Three kinds of divergence:
1. Divergence at epistemological level
A forma mentis rooted in a HOLISTIC CULTURE
Examples:
• focus to phenomenology
• intentionally rough definition of concepts
• …
A forma mentis rooted in a REDUCTIONIST SCIENCE
Examples:
• focus to ontology
• attempt to an exact definition of concepts
• …
Three kinds of divergence:
2. Divergence in methodological approaches
A preference for a real and generalist knowledge
Examples:
• focus to decoding reality
• non formal methods for design
• …
A preference for abstract and specialistic thinking
Examples:
• focus to encoding models
• formal models for analysis
• …

Purpose of the model Urban actors and activities
Analytical perspectives Allocation and spatial patterns
Observation, information Drive of spatial processes
User interface and evolution
Links belonging to the external loop
Links belonging to the internal loop
Elements more sensitive to simulation
Three kinds of divergence:
3. Divergence in practical applications
A mind orientation to exploitation of professional expertise
Examples:
• looking at empathy with the customer on the problem
• searching the most passable solution for the customer
• …
A mind orientation to scientific discovery
Examples:
• looking at the best setting of the problem
• searching the most rational solution
• …
An example of “physics of the city” approach:
D. Helbing’s modelling of traffic or stampede in panic situations
An example of “cognitive city” approach:
G. Rabino’s modelling of tourists movements
D. Helbing’s modelling of traffic or stampede in panic situations
Focus to the SYSTEM of Agents
attention to:
configuration of the system (agents’ density, etc.)
physical “geometry” of the environment
interactions between actions of agents
characteristics of agents as control variables
G. Rabino’s modelling of tourists movements
Focus to the system of AGENTS
attention to:
psychology of agents (rationality, learning, …)
interactions agent-system (perception, decision …)
interactions between actions and psycho of agents:
interactions of agents as control variables
Physics of the city as a case of ECONOPHYSICS
Econophysic websites (example):
Physics of the city as a case of ECONOPHYSICS
Econophysic books (examples):
Physics of the city as a case of ECONOPHYSICS
Econophysic: the principles
Cognitive city as a case of COGNITIVE SCIENCES
Cognitive science websites (example):
Cognitive city as a case of COGNITIVE SCIENCES
Cognitive science books (examples):
Cognitive city as a case of COGNITIVE SCIENCES
Cognitive science: the principles
ECONOPHYSICS and COGNITIVE ECONOMY: the differences
On the background, 2 (untill now) open questions:
• are consciousness and intentionality epi-phenomena?
• can “rational modelling” simulate non-rational behaviour?
Differences in methods:
• ECO: Refined analytical apparatus (master equation, network theories, …)
• COG: Algorithmic procedures to handle not-explicit knowledges
Differences in theories:
• ECO: to use “universal” principles (eq. of continuity; concept of “field”; …)
• COG: to make agents real “human” agents
ECONOPHYSICS and COGNITIVE ECONOMY:a possibility for reconcilement
THERE IS NO PROBLEM AT METHODOLOGICAL LEVEL e. g. : Multi-level – multi-agents modelling:
System of agents
Agent as a system

THE REAL PROBLEM IS IN “FORMAE MENTIS”:The need (the hard task) is that each other know and truly understand the other culture and scientific paradigm
