Hotel service robots can prompt a surprisingly human response: feeling that a favour ought to be repaid.
In a survey of 462 guests in China, perceived social qualities of robots were strongly associated with emotional indebtedness, which in turn was linked to loyalty intentions.
What researchers studied
Researchers examined the social and functional aspects of robot-delivered hotel services.
Their central question was whether social presence and enjoyment, compared with novelty and performance, were related to customers feeling obliged to reciprocate for help received.
The study surveyed 462 hotel guests in China who had directly experienced service robots.
Respondents rated the robots’ attributes, their feelings of indebtedness and their intentions to revisit or recommend the hotel.
The team used structural equation modelling and compared groups with different levels of anthropomorphism: the tendency to perceive human-like qualities in a robot.
This was a cross-sectional questionnaire study, not a randomised robot-design experiment.
What they found
Social attributes were positively associated with emotional indebtedness, with a standardised path coefficient of 0.684.
Nonsocial attributes showed a negative association of −0.203 in the overall model.
Emotional indebtedness was positively related to stated brand loyalty, with a coefficient of 0.619.
The estimated indirect association between social attributes and loyalty through indebtedness was 0.334, with a bootstrap confidence interval from 0.27 to 0.45.
The strength of some relationships differed by how human-like guests perceived the robot to be.
Social attributes were associated with indebtedness in both the low- and high-anthropomorphism groups.
What it means
For hospitality managers, the findings suggest that customer responses to automation may involve more than speed and accuracy.
Social cues can accompany gratitude, obligation and evaluations of the wider brand.
However, emotional indebtedness is not automatically a desirable customer experience.
The study did not establish whether guests actually returned, spent more or preferred a robot over a human employee.
Important limitation
All measures came from a single cross-sectional survey of robot-experienced hotel guests in China.
Shared-method bias, selection effects and alternative explanations remain possible.
Statistical mediation does not demonstrate that the robot’s social behaviour caused loyalty.
