With this speakers' series the Art of Judgement Working Group fosters discussions about the role of judgements, based as they are on both existing expertise and political and ethical choices, in the formation of scientific and technological knowledge and in planning. The series carries themes broached by the group to an institute-wide audience to catalyze the development of ideas and connections.

The guest speakers address the various, occasionally unexpected ways judgements have been understood, validated, and acted upon by historical actors. Of particular relevance is here the analysis of matters of objectivity, subjectivity, and reliability and of how these relate to the production of judgements in a variety of fields of inquiry.
