London: Robots can encourage people to take greater risks in certain situations than they would if there was nothing to influence their behaviours, a new study reveals.
“We know that peer pressure can lead to higher risk-taking behaviour. With the ever-increasing scale of interaction between humans and technology, both online and physically, it is crucial that we understand more about whether machines can have a similar impact,” said Yaniv Hanoch, associate professor at the University of Southampton, who led the study.
This research involved 180 undergraduate students taking the Balloon Analogue Risk Task (BART), a computer assessment that asks participants to press the spacebar on a keyboard to inflate a balloon displayed on the screen.
With each press of the spacebar, the balloon inflates slightly, and 1 penny is added to the player’s “temporary money bank”. The balloons can explode randomly, meaning the player loses any money they have won for that balloon and they have the option to “cash-in” before this happens and move on to the next balloon.
One-third of the participants took the test in a room on their own (the control group), one third took the test alongside a robot that only provided them with the instructions but was silent the rest of the time and the final, the experimental group, took the test with the robot providing instruction as well as speaking encouraging statements such as “why did you stop pumping?”
The results showed that the group who were encouraged by the robot took more risks, blowing up their balloons significantly more frequently than those in the other groups did. They also earned more money overall.
There was no significant difference in the behaviours of the students accompanied by the silent robot and those with no robot.
Hanoch said: “We saw participants in the control condition scale back their risk-taking behaviour following a balloon explosion, whereas those in the experimental condition continued to take as much risk as before. So, receiving direct encouragement from a risk-promoting robot seemed to override participants’ direct experiences and instincts.”
The researcher now believe that further studies are needed to see whether similar results would emerge from human interaction with other artificial intelligence (AI) systems, such as digital assistants or on-screen avatars.
“With the wide spread of AI technology and its interactions with humans, this is an area that needs urgent attention from the research community,” the researcher said.
“On the one hand, our results might raise alarms about the prospect of robots causing harm by increasing risky behaviour. On the other hand, our data points to the possibility of using robots and AI in preventive programmes, such as anti-smoking campaigns in schools, and with hard to reach populations, such as addicts,” Hanoch underlined.
