Narrow impact measure a danger: Chubb CHIEF scientist Ian Chubb has warned that the impacts of research need to be defined broadly, warning that a narrow definition risks skewing the national research effort too far towards immediate outcomes. His warning comes as Commonwealth government is proposing to run a pilot next year of measuring the impact of university research in a bid to provide some greater focus on so-called applied research. It is designed to complement the current focus on scholarly excellence in the Excellence in Research for Australia assessment.
