You're assuming the truth is such you can infer it from what you 
see without going out to collect more data, and trust your 
analysis. There is no reason to assume so. We forum participants 
are likely to be a highly self-selected group.

I do understand that you have programming experience from other 
places too, but realistically you're definitely not such a 
polyglot that you can see all the bubbles from the outside. Think 
Walter. He has seen pretty much everything, yet all of us can see 
blind spots in his thinking fairly often. You cannot expect 
yourself to do much better than Walter no matter how experienced 
you are.
