For a while now I've come to the conclusion that it's important to occasionally listen to the so-called conspiracy theorists to see what's their take on just about any issue.
Of course in general if you had to bet your life, you'd be better off following some official guideline more often than not (stress on "more often"). However it's also important at some point to scrutinize things, so to keep in check those leaders that are tasked to serve the population that depends on them. This is even more important when talking about leaders that were never elected and simply came to be by virtue of raw economical power.
It's important first to understand how one should go about judging information. One big issue is that people tend to see what's true or not in a binary way, however most issues are not binary. Objectiveness is hard to reach because one first needs to define the domain of what is that bit of information that one is trying to definitely categorize as truth, and then one has to make sure that information that allows for that categorization to be made, is indeed reliable.
Different domains, perspectives and resolutions can make it much harder to come to a conclusion that is satisfactory.
To establish what is true, it's then clearly a complicated and lengthy task that we end up delegating to leaders, which appoint experts that use their knowledge and, ideally, also their best judgment.
People from the outside are assured that this is a very professional, ethical and honest structure resulting from thousands of years of civilization, and that it's peak objectivity. In reality however there's corruption at every level. Leaders tend to be self-serving and experts tend to support those leaders that are a vehicle to their ambitions, be those ambitions for wealth, fame or both.
Institutions and leaders that guide them, have a great impact on everything. Corruption can be found at any level in this chain of delegation. People are promoted not because they are honest, but because they've served well those that have appointed them, and not necessarily because they have served well the population that has elected those that have appointed them.
In all this, the "conspiracy theorists", those that are skeptical of everything, are a necessary component, because they will on occasion point so some truths (often in plain sight) that are otherwise never even considered by the general public.
