The parent post said scientists; medicine is something I've more knowledge of. You can carry the goalposts yourself, if you wanna move them around!

(The parent post also already mentions Einstein on quantum physics.)

I'm not sure about self harm or whatever, but Planck's Principle [1] was not stated without cause: 'Science progresses one funeral at a time.' And that was a quote from an outsized figure during the golden age of physics.
