In Serious Personal Conviction – on measurements of conscience, we encounter two groups of people interviewed on different occasions discussing consciousness and ethics in relation to the military system. One of the groups are men that during the 1970s and ‘80s chose to perform non-combatant service and now reflect on the choices they made as 18-year olds. The other group consists of young people of today trying to answer several questions regarding the right to take another person's life. The exposition is part of the artistic research project Refuse to Kill – stories of the conscientious objectors. Our methodology involves a montage of a large number of voices collectively collected through statistical surveys, open-call procedure via advertising in newspapers and the internet, interviews and searches in archives.
