Let's get started with a link.

http://en.wikipedia.org/wiki/Pseudoscience...al_explanations
Ok, now the things which is missing from that link that jumps out at me (a former conspiracy theorist/pseudoscience advocate who is still on speaking terms with many conspiracy theorists/pseudoscience advocates) about all conspiracy theories and many pseudoscience claims is their sensationalism. I mean, we're talking about cold fusion, false flag operations, alien abductions, monsters, high crimes and devious secret societies. Almost any conspiracy theory plays out like the plot of a science fiction movie. All it's lacking is the incorruptible hero and a plucky female love interest. Although this gets little attention in the above links, I honestly think that many true believers subscribe to these ideas for the same reasons the more skeptical among us watch sci-fi or technothriller movies. It's not just entertainment, it's the feeling we get from putting ourselves in the protagonist's shoes, saving the galaxy, the nation or some innocent civilians.
Now here's the sad part: Some of these true believers are really smart. They come up with elaborate conspiracies, research and add to other conspiracies and think up imaginative new 'theories.' So what would happen if these people actually used their gifts to better themselves?
A pseudoscientist can make claims about free energy, cold fusion or anti-gravity from now till the cows come home, but no matter how imaginative or well-modeled an idea they produce, they'll never get any recognition because their ideas are based on their own imaginations, not hard science. The conspiracy theorist can think up new and imaginative plots and schemes all day long, but will never be vindicated because their ideas are based on their own imagination, not actual events.
Here's the catch: Scientists use their imagination. So do spymasters and public officials. Someone had to think up General Relativity before it could be modeled and tested. Someone has to think up elaborate plots to garner intelligence from foreign powers.
So some of these pseudoscientists could actually win the acclaim and respect they so desperately seek. Some of these conspiracy theorists could actually be the men in black. They just need to put all that effort and imagination into doing something constructive, instead of sitting around naval gazing.
Did you know that there are ways to get your college almost completely paid for by the government and private charities? Did you know that the US Army advertises slots in the Operational Detachment Delta selection course (That's delta force, by the way) in Stars and Stripes? Wouldn't all you true believers out there be much happier actually doing the things you dream about all day?
I think so. I think the world would be a better place if people spent less time daydreaming about grand adventures and monumental achievements and started actually working towards those things. But that's just me.
