Disincentives are still here
1996 To me: “Methods/Tools are something you use for research. They are not research.” 2019 To Geoff: “You will become known merely as a tool builder rather than a serious
- scholar. A serious scholar cannot waste time
- n anything but empirical research and
advancing theory.”
