Participatory Technology Assessment

A consensus conference is the classic pTA format pioneered by the Danish Board of Technology. A panel of around a dozen to fifteen lay citizens, with no special stake or expertise, is recruited and given balanced background material over preparatory weekends. At a public conference they question a range of experts and stakeholders, deliberate among themselves, and then write and present their own consensus statement on the technology—its benefits, risks, and acceptable conditions—which is communicated to parliament, the media, and the public.

Both bring societal considerations into technology decisions, but they emphasise different things. pTA centres on democratic participation—directly involving lay citizens and stakeholders in deliberating and judging a technology, often to inform public and parliamentary debate. CTA centres on shaping design—feeding societal aspects back to engineers and managers early, while the technology is still malleable, to steer its co-evolution with society. pTA can be one method within a broader CTA or responsible-innovation strategy, and the two traditions are closely linked, both feeding into the later Responsible Research and Innovation framework.

Its influence is real but uneven. In its Danish home and several other European parliamentary settings, consensus conferences and related exercises have informed legislative debate and, in some cases, shaped regulation on issues like gene technology. Elsewhere results are acknowledged but have limited direct effect, and critics note that influence can be symbolic. pTA's value is therefore often defended on broader grounds—improving the quality of debate, surfacing public concerns early, and strengthening democratic legitimacy—rather than on direct, traceable policy change alone.
