A more recent
and sophisticated example of media construction of a drug problem--the
"Coke Plague"--is shown here. This visual image was constructed
by a graphic artist, Christoph Blumrich, for an article featured on
the cover of the March 17, 1986 issue of Newsweek, "Kids
and Cocaine: An Epidemic Strikes Middle America." The text that
appeared next to this graph made the following claim:
There is simply
no question that cocaine in all its forms is seeping into the nation's
schools. An annual survey conducted by the Institute of Social Research
at the University of Michigan shows the percentage of high-school
seniors who have ever tried cocaine has nearly doubled in the past
10 years, from 9 percent to 17.3 percent (p. 63).
However, on close inspection,
you might notice a few peculiar features of this dramatic graphic image,
which is based on the Monitoring the Future survey of high-school seniors.
First, whereas the text of the article refers to a 10 year period in
which cocaine use "nearly doubled," the graphic only shows
six years of data, 1980 to 1985. Why would the graphic artist
exclude the earlier data for 1975 to 1979? Second, although it is not
clearly indicated, the percentages in this graphic refer to lifetime
prevalence, rather than the more contemporaneous measures of annual
or thirty-day prevalence. Why include every student who "ever tried
cocaine" in this image of "cocaine usage"? Third, you
might notice that the percentages on the edge of the graphthe
"y-axis"begin at 15 percent instead of zero.
What happened to the bottom 15 percent of these data? Fourth, note that
the subheading for the graph suggests that "[w]ithin the next two
years, more than 20 percent of high-school seniors" may try the
drug. How can this graphic artist see two years into the future? Finally,
although it is not mentioned in the text of the Newsweek article
nor in the graph, none of the year-to-year changes in lifetime prevalence
from 1980 to 1985 were statistically significantthat is, these
yearly changes probably reflect random sampling fluctuations. Or, to
put it another way, the dramatic "Coke Plague" shown in this
graph was actually constructed from a flat line by the graphic artist.
In one of the readings for
this section, "Shocking Numbers and Graphic Accounts," Orcutt
and Turner examine the Newsweek "Coke Plague" and other
statistical claims about cocaine use that appeared in the print media
starting in 1986. Although many of the examples they analyze are subtle
and far less dramatic than was anti-marijuana propaganda in the 1930s,
these carefully crafted definitions of drug-related deviance may be
all the more influential as a result.
