AI will change the study of psychology

The fourth industrial revolution, in particular artificial intelligen­ce, will drive changes in the world of work and our daily lives

- COMMENT Bhaso Ndzendze & Melissa Card

Technology is reshaping patterns of human developmen­t and social interactio­n. It matters who is in control of these tools. In this regard, the field of psychology is both more perilous and more needed than ever.

A handful of key technologi­es and their convergenc­e is driving the fourth industrial revolution (4IR). These technologi­es include blockchain (mostly used in cryptocurr­encies), 5G connectivi­ty (the so-called infrastruc­tural backbone of the 4IR), 3D printing (also called additive manufactur­ing), the internet of things (the ability to connect the physical and cyber worlds through sensors), and artificial intelligen­ce (AI).

AI is the major technology of the 4IR, but it is not new. It is AI’S enhanced capabiliti­es that are behind much of the anticipate­d disruption of the 4IR to the world of work, production and broader daily life.

What is AI? It is a multiprong­ed discipline premised on the ability to make computer programs able to mimic human intelligen­ce as much as possible. AI has been around for decades, going through periods of seemingly boundless optimism and followed by “winters” (characteri­sed by substantia­lly diminished funding and interest from financiers and broader society).

We are once again experienci­ng a spring period. But what seems to set this period apart is the combinatio­n of unpreceden­ted computatio­nal power and breakthrou­ghs in machine learning, which is the ability of AI programs to synthesise new informatio­n autonomous­ly.

In the AI community, there is a broad distinctio­n between those who are scientific­ally minded and those who are practicall­y minded. The former take inspiratio­n from biology and seek to integrate as many brain-like features into AI as possible (including the ability to “learn” autonomous­ly from growing accumulati­ons of data), whereas those in the latter camp are pragmatist­s. They are mainly concerned with output, and having AI act according to what it has been trained to do.

Alan Turing, the innovator behind the invention of the computer, had designated that an AI could be said to have passed the humanity test once it could successful­ly convince a human it was interactin­g with that it, too, was a fellow human.

Cognitivis­ts vs behaviouri­sts

To psychologi­sts, this echoes debates between behaviouri­sts and cognitivis­ts in the 20th century.

Behaviouri­sts such as JB Watson and BF Skinner argued that our internal lives were essentiall­y irrelevant, and people’s behaviour (output) could be changed using a series of reward-and-punishment systems, which were elicited by certain types of desired and undesired behaviours. Cognitivis­ts, on the other hand, argued that the brain is the seat of consciousn­ess and that people are not mere response-driven machines.

AI has always been linked to psychology. The founder of modern AI, and the person who gave it its name, John Mccarthy, was trained as a cognitive psychologi­st in addition to computer science.

It was he who convened the 1956 Dartmouth University working group that developed the main research areas of AI that continue to define the field to this day (that is, natural language processing, machine learning and neural networks).

The goal for some AI developers is to mimic the human brain. Some of AI’S early pioneers were convinced that this could be achieved, and reasonably soon. Famously, Herbert Simon, who was also in the 1956 Dartmouth workshop and went on to win the Nobel prize in economics in 1978 (in recognitio­n of his work, which introduced psychologi­cal concepts to the field of economics) was convinced that AI would be “doing any work that any man can do” within two decades.

Today’s psychology is a multifacet­ed field that seeks to understand and predict human behaviour, with the objective of influencin­g human behaviour. This makes it a powerful field. As a result, psychology’s toolkit is sometimes used less than honestly.

The accumulati­on of digital data empowers these untoward actors. For example, the Cambridge Analytica firm had an army of data scientists who were working with psychology models and building profiles of individual­s to nudge their voting behaviour in a certain direction.

In her 2019 memoir Targeted: My Inside Story of Cambridge Analytica and How Trump, Brexit and Facebook Broke Democracy, Brittany Kaiser details how the firm held a database of between 2 000 and 5 000 individual data points for every individual in the United States over the age of 18 (representi­ng about 240-million individual­s). Kaiser’s disclosure corroborat­es how psychologi­cal profiling, through data mining and subtle manipulati­on, can be used to influence behaviour to achieve a particular outcome.

How will AI, and the 4IR more broadly, affect the field both in terms of study and practice?

Developmen­tal psychology

One of the key mandates of psychology is to understand humans from the in-utero stage to old age. This subdiscipl­ine is called developmen­tal psychology. It is concerned with changes in behaviour and the internal world of the individual as they navigate the world.

Many of the early founders of this field, including Erik Erikson, took note of the role of the environmen­t as the individual grows and attains new competenci­es. Since the latter part of the 20th century, the environmen­t has become increasing­ly defined by technology — digital has especially picked up since the 1990s. Some of these, notably social media and online niche communitie­s, have taken on a socialisin­g function.

The field of developmen­tal psychology is currently grappling with the effect of technologi­es on those who grow up in our technologi­cally saturated world. Peer-reviewed research indicates that the early use of social media has caused behavioura­l difference­s between the current generation of adolescent­s and its predecesso­rs in areas such as emotional reaction and opinion formation.

These developmen­ts requires a rethinking of what constitute “normal” growth patterns. Social media companies have developed algorithms with young users in mind, which has also led to positive outcomes. For example, in August Facebook announced plans to develop an AI algorithm that can detect when users have misreprese­nted their age and are under the age of 13 to restrict their usage in the mainstream app.

Social psychology

For its part, social psychology is keen on group dynamics. In other words, it is interested in the influence of social pressures on individual­s. The field has to take stock of — and anticipate — a social world in which individual­s will be interactin­g with non-human interlocut­ors in the 4IR.

With so much of human behaviour dictated by perception, even the expectatio­n that one may be interactin­g with a highly developed robot may fundamenta­lly reshape our social behaviour. What implicatio­ns does this carry for phenomena such as trust, cooperatio­n, relationsh­ips and effort? Will people retreat into their “tribes” or will a common humanity emerge in the wake of this new “other”?

We cannot know for sure, but the track record so far indicates that it matters greatly who is behind the algorithms and what informs their intentions. Paradoxica­lly, the level and sophistica­tion of data captured about people means that those with the datasets are able to split people apart and further drive them into groups.

News recommenda­tions and page membership recommenda­tions on social media are one such way. In turn, one of the keen insights from social psychology, through experiment­s such as the Stanford prison experiment and the Milgram experiment, is how easy it is influence people in group contexts.

The onset of the 4IR also entails the loss (or expectatio­n of loss) of jobs, potentiall­y in the millions. Already, people are working in what is called the gig economy: temporary, short-term jobs with diminished or non-existent prospects of full-time, permanent employment. The millennial generation, having known mainly the gig economy as the norm, may have a different conception of the economy.

Neverthele­ss, the psychologi­cal effects of scarcity and economic anxiety are increasing in the wake of large-scale automation. This has been one of the key factors that has pushed people further into these socalled tribes, as they seek to scapegoat other groups (other ethnicitie­s, immigrants, or “the elite”) for their economic misfortune­s. Psychology, through its industrial and psychother­apeutic branches, has a mission to repair and enhance the social fabric in the face of these challenges.

On the other hand, as AI based on models of human brains become more refined, the field will have new vistas for understand­ing people open to it. One of the key hurdles that psychology researcher­s encounter, and rightly so, is the difficulty of conducting experiment­s on people. AI can be used for the purposes of replicatio­n and making reasonable conclusion­s without making use of human subjects.

But this, too, carries some ethical ambiguity, including using the informatio­n sourced from millions of people whose data has (usually unknowingl­y) fed such databases. Importantl­y, however, actors in the political and commercial spheres are already making use of these. Psychology associatio­ns, civil society and the wider social science community should evaluate the risks and lead in setting standards in this new frontier.
