Clifford Nass, author of The Man Who Lied to His Laptop studied the way people interacted with computers.

In the one of his studies participants performed a task with a text‐based computer and were then interviewed about the performance of that computer on 1 of 3 loci:
(a) the same computer
(b) a paper‐and‐pencil questionnaire
© a different (but identical) text‐based computer

Consistent with the politeness prediction, same‐computer participants evaluated the computer more positively and more homogeneously than did either paper‐and‐pencil or different‐computer participants.
