I see this same pattern in psychology—there is a huge desire among early career scholars to do applied work
This is very important, but including basic science perspectives still improves the research quality

Over the past 2,000 years in Europe, there have been few periods and places of freedom. For much of the time we lived under highly oppressive tyrannies of various kinds, whether small or grand, local or imperial, secular or religious.🧵
