judge management by whether it pushes the numbers in the right
direction. Business success is judged by numbers even in areas
where numbers are hard to assess. The management “Balanced
Scorecard,” for example, pushes quantification deep into the non-
financial aspects of a company.
But numbers, and the facts they represent, are never purely ob-
jective. Any marketer will tell you that the wording of survey or
focus group questions greatly affects an-
swers, and this is the tip of the iceberg.
Every data point, however statistically
valid its construction, contains human
choices within it: choices about what is
looked for, what is counted, what it is
associated with, and how it is inter-
preted. Between one analyst and an-
other or one time and another, different
decisions will be made about what to observe, how to identify sig-
nificant instances, which ones to count, how to measure, and how
to calculate.
Moreover, data are seldom created or presented purely for our
benefit. They are more usually soldiers of advocacy, created or
chosen in order to be marched into battles over agendas and re-
sources. Purveyors of data very often selectively choose data points
to support their point of view or bring others around to it, to draw
attention away from a problem or toward a proposed solution, or
to arouse or diffuse public concern, and argue for a proposed in-
tervention or outcome.

As Joel Best, in his book Damned Lies and
Statistics—the best modern text on an old theme—says, “all statis-
tics are ammunition.” And not only are “hard” data subject to po-
litical interpretation and manipulation, but this interpretation is
often presented via the data to benefit from the natural “truth claim”
that numbers have.
