The ELIZA effect
The ELIZA effect is a tendency to read more into computer performance than is warranted by their underlying code—e.g. the psychotherapy program ELIZA gives apparently sympathetic responses, but in fact is only utilizing a set of canned responses.
The ELIZA effect was recognized and described by ELIZA's creator, Joseph Wiezenbaum, although it was given its title by Douglas Hofstadter in 1995.
