Accurate transmission of information can be seen as necessary, but not
sufficient to provide a clear pathway between publication of original
research and the wider dissemination of findings. People are selective in
the information they attend to, and there are differences in interpretation
and memory for details, including distortion of details at the point of
recall. It is beyond the scope of this chapter to provide a detailed account
of human cognition, but one important example, confirmation bias, is
discussed below.
