"NASA employed ECAST to engage in a "participatory technology assessment," an engagement model that seeks to improve the outcomes of science and technology decision-making through dialog with informed citizens. Participatory technology assessment involves engaging a group of non-experts who are representative of the general population but who unlike political, academic, and industry stakeholders who are often under represented in technology-related policymaking. ... During meetings in Phoenix and Boston in November, 2014, participants voiced their thoughts and preferences about asteroids, planetary defense and space exploration."
Keith's note: According to the report "We at ECAST designed the forums to explore what a diverse group of lay citizens thought about complex issues when provided with unbiased information and offered the opportunity to have a respectful and open conversation about these matters with their peers. Quite different from a poll or survey, forums like the one developed for this project explore the views and values that citizens use in assessing sociotechnical issues. ... ECAST undertook the recruitment of the lay citizen participants, achieving a distribution that aligned with the demographic characteristics of their respective states by taking into account gender, age, education, ethnicity, income, and employment status."
So ... how did these people from nowhere in particular get up to speed on NASA's Asteroid Redirect Mission (ARM)? According to the report "Rather than survey people who may have little understanding of the subject, these forums provided the opportunity for participants to learn a great deal about NASA's Asteroid Initiative. In fact, participants were provided with much the same technical information that NASA's administrators and program managers use, but presented in short thematic background papers provided prior to the workshop and four informational videos at the start of each session."
Ah, so they only showed the participants NASA stuff. Did the participants receive materials that were in any way critical of ARM? Seriously. The participants were being asked to weigh all aspects of ARM, asteroid defense etc. Given that Congress, the NASA Advisory Council and a significant portion of the planetary science community doubt the value of ARM and/or are totally against it one would hope that this was factored in. If the participants were not given the full spectrum of viewpoints on this topic then the entire effort was null and void at its very inception.
