We lie to robots to spare their nonexistent feelings, research finds

Having robots in our lives is an inevitability. We already have artificially intelligent voice assistants on our phones like Cortana, Siri and Google Now. But how will we interact with robots when they look and act like us? Researchers at the University College London and University of Bristol experimented with a humanoid robot to find out how humans instinctually interact with robots. Users took each robot's apology well, and were especially receptive to robot C's sad facial expression as it reassured people that it "knew" it made a mistake.
