In the era of Internnet it's impossible. Of course, there are some projects on blockchain already developed for news control, but I don't think they will be soon mass-adopted. The only way out is to perceive everything with a cool mind and never make quick decisions. And, of course, make your own life a focus of interest, not the celebrities' or politicians' ones!
You are definitely not familiar with the power of Machine Learning and Neural networks, mate. There are already algorithms which answer the "is it fake?" question with ~70% of confidence.
I totally agree with you, that you should be cold-minded and never fall into quick decisions and etc. But some events are more than that. Some of them are so hard to prove and investigate that people start to join groups and investigate that event together, and even that united process can take several months! (for example Bellingcat group and their investigation of MH-17).
That is why I think that it is more important not to "detect" fake, but to mark the source of the fake news and warn users that "trust level of this source is low, be cautious!".
And with modern technologies this is possible.
You do not need to control the news - you should take control of the information sources you are checking every day, and there will be a platform which will help with that.
