Seriously, last time we waited for the evidence it either didn't come, was long debunked, or otherwise... I'm not counting on getting anything provable...
Either way, I find it funny that people use the appeal to authority trick to question why I don't support the conspiracy theory as an architecture student... The card board boxes happen to be one reason... out of many...
Being an architecture student is a wonderful and very eye-opening experience. You gain a lot of knowledge that would generally not be accessible to the general public.
We might not be as well-versed as structural engineers in the actual building mechanics and statics and such, but the breadth of information we must interpret is immense. Especially once you actually start practicing. You don't just need to know how the building stands and how it is aesthetically pleasing, but you must be intimately familiar with the needs of the buildings occupants and *really* understand their business so that your design can meet their needs as well as is possible. But I digress.
A lot of the things you will learn in architecture school and as an architect (it never really stops, the learning) would seem rather counter-intuitive to your average layperson. For instance, I remember being somewhat shocked to learn about how structural steel could fail in a fire by weakening only, due to heat, before ever melting. Before I had that sort of education, as a layperson, I didn't really consider steel construction to be susceptible to fire because
steel doesn't burn.
Now I know more, and know better. But, I didn't used to. For that reason I think that it's our obligation to at least attempt to educate before we mock. Most die-hard conspiracists won't be receptive to it, but it's always possible that some (maybe lurkers, etc) will be able to see the logic and science behind your argument.
In the end, it's worthwhile in either case. There's no need to hoard your expertise. People might benefit from your knowledge / experience / education.
