‘Intelligence’ Definitions New English Dictionary,1932, “The exercise of understanding: intellectual power: acquired knowledge: quickness of intellect.” New English Dictionary,1932, “The exercise of understanding: intellectual power: acquired knowledge: quickness of intellect.” Macmillan Encyclopedia,1995, “Intelligence is the ability to reason and to profit by experience. An individual’s level of intelligence is determined by a complex interaction between their heredity and environment.” Macmillan Encyclopedia,1995, “Intelligence is the ability to reason and to profit by experience. An individual’s level of intelligence is determined by a complex interaction between their heredity and environment.”

Human Intelligence? In 1900’s, Binet (inventor of the IQ test) picked judgement, common sense, initiative and adaptability as “essential ingredients of intelligence”.

Brain Size Direct comparisons can be made in terms of brain size, numbers of brain cells and complexity. Direct comparisons can be made in terms of brain size, numbers of brain cells and complexity. A human brain has approximately 100 billion neurons - a sea slug’s brain has 8 or 9 neurons. A human brain has approximately 100 billion neurons - a sea slug’s brain has 8 or 9 neurons. Brain size can be used to ‘prove’ all sorts of results. Brain size can be used to ‘prove’ all sorts of results. Germany, min requirement for a professor, head circumference of 52 cms. Used to discriminate against women. A medical physicist of the time said “We do not have to ask for the head circumference of women of genius – they do not exist.” Germany, min requirement for a professor, head circumference of 52 cms.

Political Correctness These serve as examples of using a measure to come to a desired conclusion These serve as examples of using a measure to come to a desired conclusion This must be avoided in studying intelligence, yet it appears time and time again This must be avoided in studying intelligence, yet it appears time and time again Also - We should not overlook observable differences because they are not politically correct – Race/Yerkes!

Sensing & Movement Intelligence also depends on how a brain senses and activates things in the world. Intelligence also depends on how a brain senses and activates things in the world. Humans sense approx 5% of the signals Humans sense approx 5% of the signals If another being senses the world differently they are not better or worse, merely different. If another being senses the world differently they are not better or worse, merely different. It is wrong to say that a creature or machine is stupid because it cannot make a cup of tea (Tylden) – this is a human task. Only in comparing humans should such a task even be considered as some measure.

Alien View You are an alien inspecting earth from afar. You are an alien inspecting earth from afar. What are the intelligent life forms on earth? What are the intelligent life forms on earth? Vehicles, networks, water, clouds, animals, bacteria, televisions? Vehicles, networks, water, clouds, animals, bacteria, televisions? You might apply some tests based on your own concepts of life form and intelligence. You might apply some tests based on your own concepts of life form and intelligence. On your planet the main sensory input could be infra red signals – so your view of earth may not include humans as an intelligent life form On your planet the main sensory input could be infra red signals – so your view of earth may not include humans as an intelligent life form

Life Considering what humans define as the basics of life can lead to strange conclusions. Considering what humans define as the basics of life can lead to strange conclusions. E.g. nutrition, excretion, movement, growth, irritability, respiration, production. E.g. nutrition, excretion, movement, growth, irritability, respiration, production. From an alien standpoint a communications network satisfies these qualities. It could be concluded that a complex global networked intelligence is being served by small drone like simple beings, with smaller brains – humans From an alien standpoint a communications network satisfies these qualities. It could be concluded that a complex global networked intelligence is being served by small drone like simple beings, with smaller brains – humans

Subjective Intelligence What we regard as being an intelligent act, and what not, is very subjective What we regard as being an intelligent act, and what not, is very subjective Human centred – e.g. jokes Human centred – e.g. jokes Animal centred – bat’s ultrasonic sense Animal centred – bat’s ultrasonic sense Machine centred – maths, memory Machine centred – maths, memory

Subjectivity - examples When a puppy walks by the side of a person, this can be considered to be an intelligent thing When a puppy walks by the side of a person, this can be considered to be an intelligent thing Maybe the puppy is satisfying a programme Maybe the puppy is satisfying a programme When a human can rapidly calculate maths or remember facts these can be regarded as intelligent acts – or they could be regarded as entertainment When a human can rapidly calculate maths or remember facts these can be regarded as intelligent acts – or they could be regarded as entertainment Between species - big problem of comparison.

Mozart? Why does playing music by Mozart to a baby in the womb make the baby more intelligent, whereas playing Rolling Stones music is dangerous? Why does playing music by Mozart to a baby in the womb make the baby more intelligent, whereas playing Rolling Stones music is dangerous? Is there any scientific basis at all for such conclusions? No. Where are the conclusive scientific studies that have shown these things to be so? There are none. Is there any scientific basis at all for such conclusions?

Social Bias A social bias runs through human educational systems - results in values associated with subjects A social bias runs through human educational systems - results in values associated with subjects An individual can be regarded as being stupid because they do not know a particular fact, cannot carry out a mathematical calculation or deal with some aspect of everyday life. An individual can be regarded as being stupid because they do not know a particular fact, cannot carry out a mathematical calculation or deal with some aspect of everyday life. But this merely represents one aspect of their intelligence But this merely represents one aspect of their intelligence

Species Bias Humans use the same approach to make comparisons with other creatures or machines. Humans use the same approach to make comparisons with other creatures or machines. We do not give value to non-human abilities, because we do not understand them We do not give value to non-human abilities, because we do not understand them We give value to animals (or machines!) copying some aspect of human abilities – Dolphins are intelligent because they do tricks - sharks are ‘mindless’ killing machines because humans do not share the same values as a shark.

Comparisons When assessing the intelligence of a machine, if we wish to claim that it is not as good as a human, we can make comparisons of the machine’s abilities in a field in which humans perform well When assessing the intelligence of a machine, if we wish to claim that it is not as good as a human, we can make comparisons of the machine’s abilities in a field in which humans perform well We can compare human abilities with a machine in a field in which the machine performs well – but the result is not so good for humans, so we don’t do it We can compare human abilities with a machine in a field in which the machine performs well – but the result is not so good for humans, so we don’t do it

End Points Intelligence is subjective Intelligence is subjective Need a broader view Need a broader view Consider intelligence in animals Consider intelligence in animals For AI we do not just wish to compare machines with humans – we must remember animal intelligence For AI we do not just wish to compare machines with humans – we must remember animal intelligence
