UC researchers believe robots can persuade people to conform
March 24, 2014
A team of University of Canterbury (UC) researchers and scientists believe robots can persuade people to conform through
group pressure.
PhD student Juergen Brandstetter has been exploring how a group of robots can actually influence people when their
numbers are in the majority.
Brandstetter surveyed almost 50 people in a room, one at a time with four robots. Results were promising and largely
confirmed that the robots could encourage a single person to conform with the group.
One of the tests included speaking in the past tense and the evidence from the survey suggested robots can influence
language and further influence human opinion.
``Even though each person knew exactly what was right or wrong, the person unintentionally agreed with the group of
robots a significant number of times.
``Our results showed that robots can induce conformity but to a significantly lesser degree than humans. We also found
that there is substantial difference between visual and the verbal tasks. But we are convinced robots are capable of
changing our behaviour even though they are still not as influential as humans can be.
``We measured the impact robots have on the English language and looked at the conformity rate robots have on people.
The results showed that people would follow robots. Robots clearly pushed people into using the wrong English tense.’’
Brandstetter carried out his research under the supervision of Dr Christoph Bartneck from UC’s HIT Lab NZ and support
from UC’s New Zealand Institute of Language, Brain and Behaviour and theNorthwestern University of Illinois.
``This research is important to New Zealand and society as the digital ager intensifies. Nearly 160,000 robots were
commercially sold worldwide in 2012 and the sale of industrial robots to the automotive industry continues to increase.
``Asia, including Australia and New Zealand, was by far the biggest market with 84,645 industrial robots sold. One of
the Government’s 10 National Scientific Challenges announced last year included robotic development. Some New Zealand
companies are developing industrial robots.
``We will one day soon see personal robots that could help assist elderly people living alone, or taking care of
children and offering information in public places. Japan is the world leader in this area and they are developing
robots for their domestic market.
``We already have more mobile phones than humans and that we expect that the ratio of robots to humans on this planet
will shift in the future strongly towards a majority of robots.
``Researchers at UC can offer their expertise to industry and work together to create a totally new industry with the
obvious benefit to the New Zealand public,’’ Brandstetter says.
