But I am not sure if we both mean the same things when we use the word "conspiracy". It's not a secret, for example. that cocolate has a slave labor problem. Planned obsolescence is not a secret (but it's more complex than just someone trying to screw you over). I don't think I understand the conspiracy aspect of the rest of your examples, save for the obvious JFK conspiracy theories.

I would put to you: If the chances of this blowing up is rather close to zero, how do you know about it ?
