If they correct the mistakes then no harm no foul. People who make mistakes and don't have an agenda should have no problem changing the false figures.
I think a major problem in the press today is the pressure to make money. This means a lot of articles needs to be delivered to generate 'clicks', so there's no time to do proper research, as there's always the next newsbit that needs to hit the digital presses. So even if some journalists wanted to be better, they're often forced into this news-whoring by their media-firm.
And sometimes I wonder if some of the journalists simply are not the brightest bulbs in the drawer. It's also sad that a lot of journalists seems to be more interested in the 'story', than facts, ideas and visions.
Personally I do not have much respect for the average journalist anymore, to the extent that I would decline any and all requests for talking with them or being featured.
