Nedra and I enjoyed the presentation of Naomi Oreske at Indiana
University’s Patten lecture. She
discussed why scientists become controversial over certain issues regardless of
whether they endorse, reject, or ignore the applications of science to society. She argued that from 1865 to 1945 science was
largely regarded as championing reason, responding to social needs such as
public health or helping farmers and manufacturers and promoting the idea of
progress and civilization. She calls his
the Aspirational Era. It ended in
1945 because science, for the first time, had developed weapons of mass
destruction that entered a worldwide arms race.
She called this the Existential Era
of science. It led to efforts by scientists to speak out, Einstein and Nils
Bohr were its major advocates. By 1950 a
third effort emerged that she calls the Select
Committee Era in which presidential science advisors, and agencies of
government were used to advise Congress on legislation. It was the era that banned DDT, enabled
legislation on acid rain, and pitted “truth to power.” The present era, which began in 1973, she
calls the Assessment Era, It began with
President Nixon abolishing the Presidential science advisor position because he
resented the scientific criticisms of the use of napalm , carpet bombing, and Agent
Orange spraying in the Vietnam War. It
has forced science to criticize government individually or through its own
science organizations.
The distancing of government from science advising creates a
tension between “crying wolf” and “fiddling while Rome burns” among
scientists. If they fail to advise they are
blamed for their cowardice. If they do advise
and their fears do not come to pass, they are accused of being extremists or hysterical. In her discussion of climate change, she
showed why the ban on fluoridated carbon
compounds used as refrigerants and in can sprays worked to lessen the
ozone hole at the south pole that was associated with these compounds in the stratosphere. It was relatively minor in its economic
impact to ban these compounds. The
manufacture was almost entirely done by one company (DuPont). There were alternative chemicals that could
be used. And DuPont made hundreds of
other products that were profitable. But
climate change is largely directed at fossil fuels and the companies that
extract them only do that and most of the world feels economically tied to
fossil fuels for its cars, utilities, airplanes, and a substantial part of the
economy. That is why these companies hire
scientists to present their views as legitimate science. They have the money to hire many scientists
to publish papers that are contradictory and they will keep submitting peer
review rejected papers until they find a journal that will publish that
work.
Scientists in general try to avoid going public with the
implications of their work because they feel they lack expertise in politics,
they fear loss of credibility,, and they prefer to be in their laboratories. Oreske feels scientists need to add a moral dimension
to their science. If their work can lead to harm and they see this, they should
speak out. She feels they should enlist
the support of moral leaders, like the Pope or the leaders of most of the world’s
religious community who favor a stewardship role of mankind for nature. She argues that a major role of science is to
improve out lot and this includes being a whistle blower when bad outcomes are
recognized by scientists through their work.
