Title: Sound Science or Scientific Uncertainty
1Sound Science orScientific Uncertainty
- Sound Science is currently a frequently used term
- Often used by government agency spokesman or
member of Congress to describe the scientific
research used to justify a claim or position - Without context, sound science has no specific
scientific definition as such, the phrase is
used subjectively
2Sound Science orScientific Uncertainty
- Lack of sound science is a common critique when
attempting to discredit proposed policies - Bush Administration touted Sound Science as the
center piece of natural resource policy - Peer-review
- Empirical Data
- Sound Science Caucus in House of Representatives
- August 2003, Office of Management and Budget
proposed to increase role of peer-review in
evaluation of scientific research conducted by
federal agencies
3Sound Science orScientific Uncertainty
- Clintons Executive Order 12866 required the use
of the best scientific information when making
policy decisions - December 2000 Information Quality Act, all data
disseminated by Federal agencies meet tests of
quality, objectivity, utility, and integrity
4Sound Science orScientific Uncertainty
- Some uses of Sound Science over time
- 1983 Dow Chemical used sound science to show
that dioxin pollution in Michigan did not pose a
human risk - 1993 The Advancement of Sound Science Coalition
to argue against regulation of secondhand smoke - Funded by Phillip Morris
- Model most current opposition groups follow to
discredit proposed policies or regulations - 1994 Contract with America frequent use of
sound science when describing reform of
environmental regulations - Office of Technology Assessment
5Sound Science orScientific Uncertainty
- Some uses of Sound Science over time
- 1996 National Association of Manufacturers
supported Bob Doles use of sound science - 2001 Energy Task Force, open more of Alaska to
oil drilling based on sound science and best
available technology - 2003, Responsible Industry for a Sound
Environment, noted sound science in promoting
pesticide use
6Sound Science orScientific Uncertainty
- No longer a concept, but rather a movement
- Introduce doubt into proposed regulatory policies
- Manufacture uncertainty
- Give outliers, skeptics, the same level support
as peer-reviewed scientific results - Hearings where Congress decide what position is
more scientifically accurate - Goal is to discredit scientists and scientific
findings - Under the guise of sound science, federal
scientific agencies have been hamstrung by
burdensome new obligations and effectively
prevented from doing their jobs - Weight of evidence
- Theory vs theory
7Sound Science orScientific Uncertainty
- Weight of evidence
- Sound science is interpreted as a position that
means requiring higher burden of proof before
action can be taken to protect public health and
the environment - Not a scientific position
- Contrast to precautionary principal
- Accumulation of information to support a proposed
solution to an issue should be the preferred
approach. - Theory vs theory
8Sound Science orScientific Uncertainty
- When considering the use of science in
formulation of policy, you must recognize
uncertainty - Uncertainty over the magnitude of environmental
problems, causes, and future impacts needs to be
considered in policy - Not to be used as an excuse not to make rational
policy decisions
9Sound Science orScientific Uncertainty
- Scientific uncertainty is the defining feature of
natural resource policy - Certainty may come too late to design optimal
legal and policy responses - Use incomplete information to make todays
decisions to address tomorrows issues - Use of estimates and preponderance of evidence
10Sound Science orScientific Uncertainty
- Role of mitigation
- Ecological function, needs
- Cause of issue/problem
- Simplistic
- Complex interaction among multiple environmental
impacts, cumulative actions - Salmon which action is most damaging? Silt,
dams, overfishing, hatchery fish, water use,
drought, pollution, predation
11Sound Science orScientific Uncertainty
- Address all impacts or determine which one is
most detrimental and only address that one - Frequently solve one impact causes problems
elsewhere - Overwhelming question do we wait until we have
better information or take early action in face
of potentially serious threats - Both imposes costs
12Sound Science orScientific Uncertainty
- How to act in face of uncertainty
- Develop better information
- Precautionary principal used in international
environmental law change burden of proof from
those challenging offending activity to those
wishing to commence activity - Adaptive Resource Management
- AHM
13Sound Science orScientific Uncertainty
- Rational model to policy assumes clear goals that
are agreed upon by all complete and reliable
data problems defined range of policy options
identified effects are understood and
predictable and final choices maximize
previously stated goals - Incremental model to policy have unclear goals in
conflict missing information or unreliable
options poorly defined or ignored piecemeal
policy
14Sound Science orScientific Uncertainty
- Move toward rational model through use of
analyses risk and economic - Need to be able to compare and contrast problems,
issues, and choices - Risk Assessment
- Many books
- Journal Human and Ecological Risk Assessment
- Usually related to chemicals, but other impacts
are being assessed using these procedures
15Sound Science orScientific Uncertainty
- Concept of risk is central to environmental
policy - Environmental problem risk (possibility of
suffering harm) - 2 dimensions
- Probability or likelihood of harm
- Severity of harm
- Defined as the probability of harm multiplied by
its consequences
16Sound Science orScientific Uncertainty
- Natural Resource policy makers work in 2
categories of risk - Harm to human health
- Acute (immediate) and chronic (long-term)
- Debate usually centers on chronic because of
uncertainty about source of problems or if exists - Harm to ecological resources
- Environmental protection usually thought of as
ecological risks but health and ecological risks
overlap - Greater variety of life affected, wide range of
impacts, many different scales (assess risk at
each)
17Sound Science orScientific Uncertainty
- Risk assessment mostly in health arena, but
ecological assessment is growing as more
information becomes available - Perceptions of risk results from where people get
their information. Perception influences views. - Need education for an accurate understanding of
risk - A gap between science and lay public
18Sound Science orScientific Uncertainty
- Ecological risk assessment is the practice of
determining the nature and likelihood of effects
of actions on animals, plants, and environment - Deals with human-caused changes
- Risks can be local (landfill), regional
(estuary), or global (climate change) - Scale is important to recognize risk to
species, community, ecosystem, or biome
19Sound Science orScientific Uncertainty
- Risk Assessment
- Organizes information and contributes to informed
decisions - Highlights greatest risks
- Typically involves modeling scenarios
- Explicitly identifies environmental values and
functions of concern - Identifies knowledge gaps
20Sound Science orScientific Uncertainty
- Risk Assessment Steps
- Clearly define the problem
- Analysis of potential impacts
- Rating the risks of potential impacts
- Part of the decision-making process
- End point also considers analysis results, costs,
availability of technology, legal mandates,
political issues, ecological values and
stakeholder concerns
21Sound Science orScientific Uncertainty
- Use of a policy to protect against risks to human
health will not necessarily protect the
environment - Ecologically, sensitivity to impacts may be
greater than for humans - People do not interact with environment like
other species - Risk assessments with proper scientific review
and consensus provide the best summary of
knowledge and leads to sound policy in the face
of uncertainty
22Sound Science orScientific Uncertainty
- Use of a policy to protect against risks to human
health will not necessarily protect the
environment - Ecologically, sensitivity to impacts may be
greater than for humans - People do not interact with environment like
other species - In comparison, people are most concerned about
health risks that are unknown, dreaded, or seen
as catastrophic so tend to make precautionary
policy with human health - Whereas to quote a congressman environmental
laws should be made with great caution and demand
a high degree of scientific certainty
23Sound Science orScientific Uncertainty
- Risk assessment is presented as technical or
value-free side of policy - Cannot separate from politics in practice
- Process is full of uncertainty and assumptions
- Series of decisions, usually most protective
choices are made for health but not for
environment - Principal of prudent policy assumes the worst
when there is uncertainty about health risks but
not about ecological risks
24Sound Science orScientific Uncertainty
- Risk assessments with proper scientific review
and consensus provide the best summary of
knowledge and leads to sound policy in the face
of uncertainty - Policy makers must clearly communicate the risks
and decisions to the public - Summarize the results so that the public can
understand them - Distinguish scientific conclusions from policy
judgments - Describe major differences of opinion on
scientific issues or alternative conclusions that
readers can draw from the data - Explain major assumptions and uncertainties
