“…There are interesting options to be explored (again): think-aloud protocols , which have been discredited for many years (Nisbett and Wilson, 1977) and yet are a valuable source for theory testing (Ericsson and Simon, 1983); introspection (Jäkel and Schreiber, 2013), which seems to be banned from psychological methods but nevertheless offers insights into thought processes; the use of life-streaming (Wendt, 2017), a medium in which streamers generate a video stream of think-aloud data in computer-gaming; political decision-making (Dhami et al, 2015) that demonstrates error-proneness in groups; historical case studies (Dörner and Güss, 2011) that give insights into the thinking styles of political leaders; the use of the critical incident technique (Reuschenbach, 2008) to construct complex scenarios; and simulations with different degrees of fidelity (Gray, 2002). …”
