Today, artists are engaged in investigation. They probe corruption, state violence, environmental destruction and repressive technologies. At the same time, fields not usually associated with aesthetics make powerful use of it.

This combination of diverse fields is what the authors call "investigative aesthetics": mobilising sensibilities often associated with art, architecture and other such practices to find new ways of speaking truth to power.
