Like come other commenters here, I don't think it's a journalist's job to _do_ the research. However, the journalist can quite accurately report "X claims Y but says they haven't performed any research to quantify this claim". The key is to ask the question.

If there isn't such a person, then the research doesn't get done. I think this is fine, because by definition nobody cares. It's possible that only poor people care and they can't provide the funding, but then their political representatives should be able to find the funding. I accept that's not perfect, but it's generally how things work unfortunately.
