3. Being intelligent being? Herbert Simon in conclusion to his Nobel Lecture (1978) said that: “Today, we have a large mass of descriptive data, from both laboratory and field, that show how human problem solving and decision making actually take place in a wide variety of situations. A number of theories have been constructed to account for these data, and while these theories certainly do not yet constitute a single coherent whole, there is much in common among them. In one way or another, they incorporate the notions of bounded rationality: the need to search for decision alternatives, the replacement of optimization by targets and satisficing goals, and mechanisms of learning and adaptation.” Simon, Herbert. (1978). RATIONAL DECISION-MAKING IN BUSINESS ORGANIZATIONS. Nobel Lecture (http://nobelprize.org/nobel_prizes/economics/laureates/1978/simon-lecture.pdf)

4. Being intelligent being? Herbert Simon in characterising bounded rationality notes that: “it is now clear that the elaborate organizations that human beings have constructed in the modern world to carry out the work of production and government can only be understood as machinery for coping with the limits of man’s abilities to comprehend and compute in the face of complexity and uncertainty” Simon, Herbert. (1978). RATIONAL DECISION-MAKING IN BUSINESS ORGANIZATIONS. Nobel Lecture (http://nobelprize.org/nobel_prizes/economics/laureates/1978/simon-lecture.pdf)

7. Genesis of the term ‘bounded rationality’ in Simon Satisficing, a "handy blended word combining satisfy with suffice",[1] is a decision-making strategy that attempts to meet criteria for adequacy, rather than to identify an optimal solution. A satisficing strategy may often be (near) optimal if the costs of the decision-making process itself, such as the cost of obtaining complete information, are considered in the outcome calculus. http://en.wikipedia.org/wiki/Satisficing

8. Genesis of the term ‘bounded rationality’ in Simon The word satisfice was coined by Herbert Simon in 1956. He pointed out that human beings lack the cognitive resources to maximize: we usually do not know the relevant probabilities of outcomes, we can rarely evaluate all outcomes with sufficient precision, and our memories are weak and unreliable. A more realistic approach to rationality takes into account these limitations: This is called bounded rationality. http://en.wikipedia.org/wiki/Satisficing

9. Being intelligent being? The foundational statement that lays the groundwork for much of the work in behavioural finance, was made by one of the key workers in computing (artificial intelligence), psychology (problem solving), and economics (organisational economics)  Herbert Simon. For Simon, there are four main areas which have a symbiotic relationship with behavioural finance: Utility Theory and Human Choice Psychology of Problem Solving Organisational Decision Making Theories of the Business Firm Simon, Herbert.

13. Being intelligent being? with apologies to Plato Knowledge about, knowledge by description: knowledge of a person, thing, or perception gained through information or facts about it rather than by direct experience. Language; Images Symbols; Planning; Learning, Thinking; Creativity An impersonation of intelligence; an intelligent or rational being; esp. applied to one that is or may be incorporeal; a spirit COGNITION: The action or faculty of knowing taken in its widest sense, including sensation, perception, conception, etc., as distinguished from feeling and volition.

14. Knowledge, Cognition and Intelligence • Knowledge is acquired and disseminated by intelligent and cognate beings. The terms knowledge, cognition and intelligence are used interchangeably. • And there is a good reason for this: Various cognitive processes help in converting information and stimuli into knowledge. Knowledgeable beings then act intelligently because of their greater awareness.

16. Knowledge, Cognition and Intelligence Human Information Exchange: The role of cognition, perception and movement In everyday language cognition is used to refer to the 'higher' mental processes. In psychology cognition would generally be taken to include a variety of mental activities.

17. Knowledge, Cognition and Intelligence Human Information Exchange: The role of cognition, perception and movement Cognitive faculties include attention, control, categorisation, creativity, decision making, language, learning, mental imagery, memory, problem solving, reasoning, representation. Perceptive capabilities enable humans to hear, see, smell, taste, and touch. These capabilities help humans to translate a variety of environmental input, for example, acoustic, chemical, electromagnetic, mechanical, thermal, into a language which can be understood by the human nervous system. Motor skills underpin the cognitive faculties and perceptive capabilities through the complex network of muscles and nerve fibres for receiving inputs from and providing output to the external environment. Cognition, perception and movement helps humans to exchange

18. Knowledge, Cognition and Intelligence Kinds of Knowledge: Cognitive psychologists have studied experts, in the physical, medical and engineering sciences, involved in problem solving, ranging from diagnosis, mental calculation, design and planning for example. The psychologists have also observed skilled performance in taxi driving, typing for instance. The observations have led to six major findings (Glaser 1994:140-141):

19. Cognitive Processes • Cognition is a broad term which is used to refer to activities like thinking, reasoning, conceiving, solving problems, learning, communicating through language and through other symbol systems.

20. Cognitive Processes • Cognition, or rather cognitive,is almost invariably used whenever an agent (ANIMAL, HUMAN or ROBOT) is • seen to be usingabstraction; • seen to be using complex rules; • seen to be usingmentalimagery; • said to have intended to act on his,her or its own; • said to have used a symbol system.

21. Cognitive Processes: Some Definitions INTELLIGENCE :=Perception+Cognition+Motor Control. Perception : Reception/analysis of sensory stimuli Motor control: Pertaining to or characterizing that which involves the systematic use of muscles; Cognition: Related to activities that involve abstraction, symbolization, insight, rule use, imagery, belief, internationality, problem-solving, language-based communication

22. Percepts, Movements and Concepts? • The sensory organs receive information about the world about us; this information is processed by the brain; and the recipient ignores/reacts to the processed information. The reception, processing and reaction involves muscular movement • The perception of sound can relate to the cognition of speech or music; the controlled movement of limbs can relate to the cognition of dance movement.

23. Cognitive Processes • COGNITIVE PSYCHOLOGY is a branch of psychology that emphasises internal, mental processes. • In cognitive psychology (COG PSY) human behaviour is discussed not in terms of its overt properties but at an abstract level: • mental events • Mental representations • beliefs • intentions

24. Cognitive Processes: An example ~ Information Processing • Any intended input, any idea,image,fact,knowledge, and so on, counts as information in COG PSY. • Processing in COG PSY usually means moving towards some GOAL by going through a series of STAGES or a SEQUENCE of acts.

25. Cognitive Processes: An example ~ Information Processing • Information processing involves cognitive processes that can deal with the organization, interpretation and responding to an incoming stimulation; PROCESSING := ORGANISATION+INTERPRETATION+RESPONSE; INFORMATION:= INCOMING STIMULATION

26. Behaviour and Cognition The Nature of Expertise One view of human expertise is that some people have spent so much time solving problems in one particular domain that they ‘know all there is to know’ (nearly) and are able to see any problem as an instance of a class of problems with which they have been confronted before. Once the expert has successfully classified or recognised a new problem as an instance of a previously experienced problem type, all the expert has to do is apply whatever solution proved successful in dealing with that type of problem in the past.

27. Behaviour and Cognition Cognitive psychologists have studied experts, in the physical, medical and engineering sciences, involved in problem solving, ranging from diagnosis, mental calculation, design and planning for example. The psychologists have also observed skilled performance in taxi driving, typing for instance. The observations have led to six major findings (Glaser 1994:140-141):

44. Behaviour and Cognition: The role of knowledge Wang (2009) looked at the relationship between the ‘increasingly complex financial products in the marketplace’ and ‘investors’ financial literacy’. The author conducted a questionnaire survey to see ‘how different male and female investors’ financial knowledge and risk-taking behavior are’ (ibid:204).(Wang 2009). Wang, Alex. (2009). Interplay of Investors’ Financial Knowledge and Risk Taking. The Journal of Behavioral Finance. Vol 10, pp 204-213.

45. Behaviour and Cognition: The role of knowledge • Wang used ‘survey data focusing on investing in mutual funds as tested knowledge domain and measured behavior’ (ibid:208): • 524 participants took part, 317 male and 207 female. • 37 questions were used to measure participants’ objective knowledge regarding investing in mutual funds; these questions were based on the work in consumer research, especially on attention and comprehension of a consumer (Celsi and Olson 1988), and based on work in marketing research on the knowledge of a consumer (Moreau, Lehmann and Markman 2001). • 10 multiple-choice questions were used to reflect participants’ objective knowledge regarding investing in mutual funds • 27 true-false questions were used to measure participants’ objective knowledge about investing in mutual funds Celsi, R. L. and J. C. Olson. “The Role of Involvement in Attention and Comprehension Processes.” Journal of Consumer Research, 15, (1988), pp. 210–224. Moreau, C. P., D. R. Lehmann and A. B. Markman. “Entrenched Knowledge Structures and Consumer Response to New Products.” Journal ofMarketing Research, 38, (2001), pp. 14–29.

46. Behaviour and Cognition: The role of knowledge Distribution of scores in an on-line questionnaire on ‘investment in mutual funds’; 37 questions on the survey (Wang 2009).

47. Behaviour and Cognition: The role of knowledge Wang showed that 1. at ‘least for investors, their objective knowledge, subjective knowledge, and risk taking are highly correlated. 2. The gender of the respondent is an important factor that differentiates investors’ levels of objective knowledge, subjective knowledge, and risk taking. Wang has argued that ‘it is investors’ subjective knowledge that mediates their objective knowledge on risk-taking behavior. Since male investors have higher subjective knowledge and objective knowledge than female investors, they often takemore risks because of the mediation effect of subjective knowledge’ (2009:212) .

48. Behaviour and Cognition: The role of knowledge The management of financial risk depends upon an organisation’s base of knowledge, access to capital and ICT resources, and the accumulated experiential knowledge. An organisation is in itself an agencement: The knowledge, capital and technological resources, have to be seen in the context of the manner in which individuals manage and operate within the organisations, what is the balance of rights and duties, rewards and punishments: in short what is the culture of the organisation, the skills of its owners and workers, and how is it the agencement works.

49. Behaviour and Cognition: The role of knowledge • There is a need to facilitate the communication across all the facets of the organisation. Knowledge has to be created, shared, validated and REGULARLY pruned. Seeding, fertilising, nourishing and pruning are the HALLMARKS of a sustainable eco system. • A sustainable eco-system has redundancy built into its operational mechanisms and allows the system to take advantage of opportunities, to weather dearth in opportunities, and to recover from disasters and overindulgence. • Sustainable eco-systems have well integrated components and have contingencies to deal with failures in the various sub-systems: Each sub-system is familiar with the operation of other proximate sub-systems. • A sustainable eco-system is an OPEN system
