> Service robots depicted in the study were the same except for the use of gray or pink colors to portray male or female genders, respectively. After receiving a menu recommendation, participants then rated the robot’s persuasiveness.

So they found out that different colors have an effect on how persuasive people perceive robots to be? And then they just claim that this is due to genders they associate to the colors? Their metric of a self reported sense of power also seems dubious to me.

This looks like junk science to me.
