The answer is more people with a background in STEM should go into journalism. Sadly, that sort of specialization is expensive and the public's willingness to spend on news seems to have gone down.
Maybe the answer is that people without a STEM background should get out of science journalism?
The question mark is genuine- would this be a bad thing for some reason?
Not that scientist journalists don’t also make mistakes of course- I’ve seen plenty, usually due to covering topics outside their own specialty.
