Descriptions of experimental conditions in study 1.

Experimental conditions	Competence high	Competence low
Anthropomorphism high	Video of shell game with robot “Pepper,” who is right in three out of four trials, speaks with a humanlike voice and points out the shell in question.	Video of shell game with robot “Pepper,” who is right in one out of four trials, speaks with a humanlike voice and points out the shell in question.
Anthropomorphism low	Video of shell game with robot, who is right in three out of four trials, presenting its answers written on its tablet's screen without voice or gestures.	Video of shell game with robot, who is right in one out of four trials, presenting its answers written on its tablet's screen without voice or gestures.

Experimental condition competence high x anthropomorphism high, n = 37.

Experimental condition competence high x anthropomorphism low, n = 41.

Experimental condition competence low x anthropomorphism high, n = 33.

Experimental condition competence low x anthropomorphism low, n = 44.
