It’s not, but it is possible to be a really high achiever and a good person. It is often implied that there is some sort of trade off.
With the field already struggling, and the COVID pandemic causing of tsunami of consequences at all levels of the economy and healthcare system, I expect this rhetoric to be EXTRAORDINARILY cranked up this year.
Excuses I expect to hear a lot about in-person and on Twitter (as well as ASTRO, if it happens):
1) Our normal pool of RadOnc applicants has shrunk further because people couldn't do home/away rotations and "fall in love" with the field
2) The competitiveness of our applicants has decreased because of #1
3) However, while they may be fewer in number and weaker in terms of applications, they DEFINITELY love their patients and are more passionate doctors
4) ...implying prior applicants with stronger applications lacked the "intangibles" we're projecting onto the current crop of kids
Then, with Step 1 becoming pass/fail, it will be difficult to observe the decline in competitiveness, except through application numbers. This will save academic department leadership from having to explain away uncomfortable trends.
COVID is a turning point in RadOnc. We could either 1) embrace the systemic disruption to massively reduce the number of trainees, or 2) embrace the systemic disruption (including the Step 1 change) and rally around the battlecry of "cancer is not elective", changing absolutely nothing about our system and pinning the decline on COVID while saying future applicants are more dedicated to the field - "people became much more interested in Pulm Crit/ED/public health etc and those fields pulled away kids who might otherwise have pursued RadOnc, but that just means we're left with the most dedicated of the dedicated!"
I know which track my money's on.
