- Abstract
- Several prominent scholars suggest that investigations of human information behavior or "information needs, seeking, and uses" rarely measure how received information is applied or its effects on the recipient, that is, its outcomes. This article explores this assertion via systematic analysis of studies published in journals between 1950 and 2012. Five time periods and four journals were sampled, including 1,391 journal articles, 915 of which were empirical studies. Based on these samples, the percentage of studies of information outcomes climbed from zero in the 1950s and 1960s, to 8% in recent research reports. The barriers to studying information outcomes and possible future research on this topic are explored.

- Abstract
- The diffusion of the Internet has radically expanded the readily available sources for information of all types. Information that was once obtained second-hand from friends and acquaintances-the traditional "two-step flow"-is now found easily through the Internet. The authors make use of survey data to explore this thesis in regards to information sources about genetic testing and the influence of the Internet an the information seeking behaviors of the public. A telephone survey of a random sample of 882 adults asked them about their knowledge of, concerns about, and interest in genetic testing. Respondents were most likely to first turn to the Internet for information about cancer genetics, second to public libraries, and third to medical doctors. Overall, doctors were the most likely source to be consulted when second and third choices are considered. Age, income, and self-reported understanding of genetics are shown to be predictors of whether someone goes to medical professionals for advice, rather than to the Internet or public library. The results raise questions about the apparent tendency of the public to regard the Internet as the best source of information an complex topics like genetics, for which it may be ill-suited.
