Virtually every organization tries to downplay rather than promote bad news--this is not an excuse to believe every rumor that you hear about that organization or person.
That is an excellent way to trick yourself into a host of verifiably false beliefs propagated by special interest groups, and a testament to the success of Washington's propaganda apparatus.
For example, you would believe that China didn't effectively contain COVID-19 as the CPC and Chinese media claimed, even though there are countless visible correlations that verify, e.g. measures of economic activity that cannot reasonably be spoofed.
