How should we evaluate the effectiveness of scientific predictions in the policy process?
I. What is the policy goal(s) (i.e., outcome) that prediction is intended to achieve?
- Specify the purpose(s) [policy goal(s)] of the prediction.
II. How does the process of developing predictions influence the policy process (and
- Consider alternatives to prediction for achieving the purpose. Maintain flexibility of
the system as work on predictions proceeds.
- Recognize that a choice to focus on prediction (as well as the choice of specific
predictive technique) will constrain future policy alternatives.
III. What are the direct societal impacts of the prediction?
- Consider alternative societal impacts that might result from the prediction (including
the different roles played by prediction).
- Evaluate past predictions in terms of a) impacts on society.
- Recognize that the prediction itself can be a significant event.
- If possible, [Subtract the costs/Assess the impacts] of inadequate predictions [from the
benefits/relative to the impacts] of successful ones.
IV. What are the scientific limitations and uncertainties of the prediction?
- Evaluate past predictions in terms of b) scientific validity.
- Recognize that different approaches can yield equally valid predictions.
- Recognize that prediction is not a substitute for data collection, analysis, experience,
- Recognize that predictions are always uncertain; assess the level of uncertainty
acceptable in the particular context.
- Beware of precision without accuracy.
- Recognize that quantification and prediction are not a) accuracy; b) certainty; c) relevance; d) reality.
- Computers hide assumptions. Computers don't kill predictions, assumptions do.
- Recognize that the science base may be inadequate for a given type of prediction.
V. What factors can influence how a prediction is used by society?
- Recognize that prediction may be more effective at bringing problems to attention
than forcing them to effective solution.
- Recognize that perceptions of predictions may differ from what predictors intend and
may lead to unexpected responses.
- Recognize that the societal benefits of a prediction are not necessarily a function of
- Recognize that there are many types of prediction, and their potential uses in society
VI. What political and ethical considerations are raised by the generation and
dissemination of a prediction?
- Pay attention to conflicts of interest [among those making predictions].
- Understand who becomes empowered when the prediction is made. Who are the
winners and losers?
- Pay attention to the ethical issues raised by the release of predictions.
VII. How should predictions be communicated in society?
- Make the prediction methodology as transparent as possible.
- Predictions should be communicated a) in terms of their implications for societal response and b) in terms of their uncertainties.
VIII. Is the value of a prediction contingent on international context?
- Predictions should be developed with an awareness of international context.
