Next time you assemble a set of shelves, see how you feel afterwards. Accomplished? Proud of yourself? That's called the IKEA effect, and it's well-known to the furniture industry.
Now, however, researchers at Penn State University have found that the same principle applies to robots. People who took part in a study on robot assembly tended to feel more positive about the machines if they helped to make them.
'Damnit, there's a piece missing'
But they also found something that IKEA-assemblers will be familiar with - participants who had difficulty assembling or programming their robots were less likely to rate the bot highly.
Sundar says that robot makers should take this phenomenon into account when they're packing up their bots.
"The manufacturer should give the customer a sense of ownership and a sense of accomplishment, but without making the process feel too painful because if the perceived process costs are too great, robot evaluation is going to suffer."
He added that this can go beyond the assembly phase too: "While self-assembly can provide an initial sense of accomplishment, the sense of ownership can be sustained with tailoring options that users can continue to tinker with, long after the initial set up."
