The difference between a professional and an amateur in this game...
Professionals connect the dots between seemingly unrelated things that actually do have a foundation or a connection in their relationships and evaluate degrees of viability and veracity.
Amateurs simply assume there are these connections because they want them to be there, and/or they simply "believe" they "might" be there. To be fair many amateurs are semi professionals and the true issue is with those who simply do not know what they are doing, don't take the time to learn what and how they should be doing things, and throw caution to the wind, typically for benefit of an ideology or an agenda. All too typically, foolish ones.
There is also a degree of their wanting to appear smarter than they are, also typically without putting in the grunt work to build those mental muscles and skills. Then even when they do put in the grunt work, they end up building those mental muscles in all the wrong ways, leading them further from the truth rather than ever getting closer to it.
Professionals on the other hand, get better and better at their deductions deliberations. While those amateurs seem to simply get worse and worse as their beliefs become more and more far fetched.
It's rather like navigating a ship. If you chart a course at the beginning and it's wrong (because you really don't know what you're doing), in your being off by even a degree at the start, you will eventually end up in another and wrong country at the end. One also has to do course occasional corrections.
Two things conspiracy nuts typically don't seem to even know about. There are a few things one can do to avoid these mistakes. Like starting out to shoot down your accept beliefs. Searching for the "Truth" regardless where it leads you. And being willing to keep an open mind. Whenever you fun into something that seems too good to be true, because you want to believe it, be wary of that and dig much deeper.
There is truly little reason to be made a fool of, by oneself.
