Science's reputation for purity suffered two major setbacks in the pas
t ten years: scientists' capabilitY to regulate themselves came into s
erious question; and burgeoning entanglements between universities and
industry created additional incentives for misconduct in research. In
this article, the author seeks to shift attention from compliance to
the definition Of the standards themselves and to suggest that there i
s less agreement about acceptable norms of behavior than is commonly s
upposed among critics of science. Further, this lack of clarity is in
Part a consequence of the fragmentation of research communities at the
forefront of science. Contrary to popular misconception, there is no
abstract, universal ''scientific method'' that guides practice in all
situations. The most Promising way to deal with criticisms of scientis
ts' integrity is to recast the problem of scientific integrity as one
of prospectively creating acceptable research practices rather than re
trospectively finding and applying them. To achieve conditions that fo
ster integrity, however, will require more than teaching research ethi
cs to graduate students or educating senior scientists in better mento
ring. Instead, the culture of science will need to confront and, where
necessary, dismantle the structural barriers to collegiality in resea
rch. As now organized, science is organized as a winner-take-all game,
with no glory or comfort for the also-ran. Would a more collaborative
science produce as many dazzling results? The burden of proof rests w
ith those who want to change the present system, but with the public i
mage of science hanging in the balance, the time may be ripe for takin
g up the challenge.
