Galton - Nature v nurture and eugenics

Sir Francis Galton  (1822-1911), the English polymath, was Darwin’s half cousin, and was enormously influenced by both The Origin of Species and The Descent of Man, especially the chapter in former on Variation under Domestication. This was to lead to his later work on ‘eugenics’, a term he coined. As a child prodigy, who left school at 16 as he found the curriculum too dull and narrowly classical, he was a mind of individual spirit, developing the modern fingerprint identification system and weather maps. He was a brilliant statistician and it was his aim to identify and quantify the nature of human intelligence. The phrase ‘Nature versus nurture’ came from Galton. 

Experimental psychology 

As an example of his approach to science, in meteorology, he gathered data at different locations, three times a day and invented weather maps based on htat data, with the arrows and symbols we see today. As one of the first experimental psychologists, he used his analytic skills, along with data, to create what is called Differential Psychology, the attempt to identify differences between people, rather than their common abilities and traits. He used many of the statistical ideas and techniques we take for granted today, including: correlation (which he used but did not invent) and observed, rather than applied, regression to the mean in his observations of breeding sweet peas. He also used natural distribution curves to analyse the data. 

This developed into a more specific inquiry into the nature of our species. He started with large data sets on physical characteristics such as height and facial shapes. This led to him developing fingerprints as a unique identifier. This was presented in Hereditary Genius (1869). 

This led to his work on specific traits that could be measured to determine cognitive abilities. This included the mental representation and imagination of numbers, including synesthesia, visualisation, word association, unconscious events, social traits, moral instincts and reaction times. But it was his work on character and personality, along with heritability that marks him out as an experimental psychologist of some note. Experimentally, and well ahead of his time in psychology, he used twin studies, both identical and fraternal, along with adopted twins, all in an attempt to separate nature from nurture. 

Eugenics 

Unfortunately, this led to his obsession with ‘eugenics’, a term he invented, to promote the marriage and breeding of traits, as Darwin had explained in The Origin of Species. It led to his belief that improvements should be sought, not by allowing hereditary wealth but by showing your personal worth, marriage among equals encouraged and the “better sort of emigrants and refugees from other lands were invited and welcomed, and their descendants naturalised.” One should note that he believed in not allowing what hesawas inferior humans to breed, encouraging them to be monastic and celibate and at times his views bordered on the recommendation of genocide. He was the founding president of the British Eugenics Society. 

Criticism 

He was often so eager to prove his hypotheses, such as the inferiority of Africans, that he refused to accept the evidence that their fingerprints were in fact not less complex than those of other races. His hereditary traits evidence often did not show up in the data, but were promoted as true. The nature-nurture debate had continued with the trend being towards it being much more complex than we mav imagined. Behavioural genetics is now a complex field, the genome has been decoded and much progress is being made to identify and solve problems using knowledge of genetics. 

Influence

Eugenics took a terrible toll across the world, with involuntary sterilisation in the US and even in Sweden until as recently as 1976 and in Japan until 1996. It has influenced immigration policies, the repression of bropups within countries and, of courses, genocides, suchas the Holocaust. Galton is now seen as a racist, eugenicist, which he clearly was. Galton was well travelled and with the spread of the British Empire in the Victorian era, he had enormous influence on attitudes towards how people were seen at home in Britain and abroad. This was to influence many aspects of intellectual and public life, not least in education, where it directly influenced Cyril Burt, who then applied this to UK policy in education, aspects of which have survived to this day. At UCL the Galton Chair of Genetics was actually renamed from the Galton Chair of Eugenics and the word Galton only changed in 2019. Yet his encouragement of statistical techniques and experimental methods to maintain objectivity have had a lasting influence in psychology.

Exemplar of successful implementation of tech in schools

Not often you see schools having resolved the ‘technology’ issue. It is usually a contentious issue, often tribal, defensive, even hostile. Despite the endless claims on workload, the refusal to do what every other area of human endeavour does, use technology to reduce it, education often seems to wilfully avoid the issue. Schools have, in the past, been quite independent, creating their own websites, buying and building their own technology, reducing much of it to a cottage industry. It was impressive to find a school network that took technology as seriously as Curro, in South Africa. They had invited me to give a keynote on AI for Learning, based on my book and experience but I hung around as the teacher sessions were so damn good. This is what I learnt, as I think it is a recipe for success.

Centralised service

Curro technology was a centralised service that provided CPD for all teachers, as well as procuring and implementing ALL technology across the entire network of schools. This is NOT simply centralised procurement, it is a group with the deep expertise needed to tackle the change management, training, trials and implementation of a range of activities. They had already implemented a wide range of technologies across the network, accessible through a single point of entry. This, I think is a necessary condition for success, single door, single sign-in. Everything from administration to advanced AI and adaptive learning systems were distributed from this point. Teachers, in particular, appreciated the simplicity of this one-stop-shop approach. It was clear that the service also had real and trusted expertise from which the whole school could draw, rather than distributing responsibility out to all teachers.

Ecosystem of technology

There was a real sense of technology as a force for good in teaching and learning. With champions out in the schools, supported by expertise at the centre, they understood the balance between innovation and implementation. This allows experimentation and constructive feedback. I got none of the tired scepticism I’ve seen elsewhere. Rather than plump for one system, they have built an ecosystem of technologies accepted by everyone. Careful choices, careful implementation and the sense that different tech meets different needs.

Emphasis on CPD

Webinars and other training is distributed, a term in advance, with practical training in hte technology, news on what’s new and other relevant services for teachers. It is clearly a dynamic service designed to bring teachers with them in the change management process. I was giving a talk as part of that process. The day’s activities were under the banner of ‘Imagining 2022’. It’s hard enough to Imagine what any year will bring these days but it was clear that this was a learning organisation, willing to learn from their mistakes and make the effort to plan forward. It was CPD organised by teachers for teachers and not scared of introducing outside ideas and speakers. There was no sense of being a protected, inward-looking process. You got that sense of CPD being in the hands of the teachers themselves, not something done TO teachers.

Content curation

The teachers were full of praise for the provision of content that they could use themselves or for students. There was no sense of the schools hanging on to the idea that ALL content has to be created and delivered internally by the existing teachers. So what of it wasn’t invented here. It was refreshing to find a sense of openness to curated content from outside sources.

Adaptive learning

This was the big surprise. There were glowing testimonials from teachers about the power of adaptive learning, using AI, to personalise learning for students. It was described as a ‘gamechanger’ by the teacher who presented, with clear targeting, so that efficient and relevant, individual interventions could be made for students. It was clear that they knew why they wanted this technology, had implemented it well and were using teacher feedback to spread the word internally.


Content, slides and short videos, along with digital worksheets, were used in class with regular assessments. A big win was saving time on marking and correction, which was automated and done instantly, even alternative question provision. This, I feel, is an argument that is massively underappreciated in schools. Diagnostic questions, provided by the system were found to be particularly useful, for identifying individual learners’ strengths and weaknesses. This meant that teachers didn’t have to wait for an assessment before making an intervention. There was also openness to including parents in the process, using the tech to allow access to their progress, lessening the need for teachers to respond to parent requests. Learners at home can also be held accountable for work in class or at home in realtime. This use of technology to extend teaching and learning was exactly what I had presented in my Keynote, using Artificial Intelligence as ‘Augmented’ Intelligence.

Conclusion

Far from being reactive to innovation they were on the front foot, seeking out the best of breed technologies. By creating a separate entity that centralised these efforts they could keep delivery safe and simple, as well as think about how to bring staff with them. The fact that I was brought in, someone 5,500 miles away, to give a talk, was a testament to their ambition and openness. I learnt more from them as they did from me. That’s as it should be.
