Even when people are completely cognizant of the existence of both stimulus and response, they appear to be unable to report correctly about the effect of the stimulus on the response. This is true in dissonance and attribution studies, in the subliminal perception literature, in the reports of creative workers, and in the work by Maier(1931), Latane and Darley (1970), and in our own studies described above.(Nisbett 1977)
