A critic mind set can help you fight against the systems that want to manipulate you, but you have to commit to find the truth, no matter how it annoys you.

The search for truth is a long one. It needs a lot of mechanisms in order to avoid biases.

In our country the system has imposed a cloud over the truth. There are no institutions to believe left alive, just a cloud of noise over another layer of noise. We only see the tip of the iceberg.

But aside that scenario there's a lot of people struggling to tell the truth, to make a common ground where everithing makes sense again. Where you can see the whole iceberg. When you find them just keep on track, don't believe every word, contrast their view with anothers, and keep looking for a more accurate model.
