“…Researchers are advised to conduct high-quality, robust research (Boyd, 2013;Whitty, 2015;Docquier, 2017;Eisenstein, 2017) and provide it in a way that is timely, policy relevant, and easy to understand, but not at the expense of accuracy (Havens, 1992;Norse, 2005;Simera et al, 2010;Bilotta et al, 2015;Kerr et al, 2015;Olander et al 2017;POST, 2017). Specific research methods, metrics and/or models should be used (Aguinis et al 2010), with systematic reviews/ evidence synthesis considered particularly useful for policymakers (Lavis et al, 2003;Sutherland, 2013;Caird et al, 2015;Andermann et al, 2016;Donnelly et al, 2018;Topp et al, 2018), and often also randomised controlled trials, properly piloted and evaluated (Walley et al, 2018). Truly interdisciplinary research is required to identify new perspectives (Chapman et al, 2015;Marshall and Cvitanovic, 2017) and explore the "practical significance" of research for policy and practice (Aguinis et al 2010).…”
