Thanks man, for your optimism that the scientific process will eventually make progress towards the truth.
Well, it's not really optimism but rather a feature of the scientific method if you think about it - while it certainly is POSSIBLE for false information to enter the repository that we call 'scientific knowledge', and this certainly happens on a regular enough basis with small things (as people pose and test new hypotheses, and they are then refuted or confirmed as the years pass), the overall trend will ALWAYS be an increase in the breadth (range) and resolution (accuracy or precision) of our knowledge. The scientific method, when applied properly, is inherently self-correcting. :)
Now, this can be likened somewhat to certain open source projects, which while yes they may be available for anyone to scrutinise and attempt to submit improvements (like scientific knowledge), there may always be areas that don't receive much attention, and these bit can contain 'bugs' for some time... but as soon as those parts become relevant and more frequently used, the bugs will be ironed out relatively quickly.
Even if every country in the world converted to official theocracies tomorrow, I believe this progressive course would not be significantly slowed unless they started killing scientists and people who think like scientists.
I've been getting impatient and have been missing that side of the big picture, and taking this whole scientific truth thing way to seriously! I gotta chill out - we'll get there eventually.
Sure thing matey - we all stand on the shoulders of giants... some generations are destined to be the equivalent of giant human pyramids (great leaps in the collective knowledge), while others may have to settle for being shoulder pads (little incremental refinements) ;)
Though maybe we have limited lifespans precisely for the reasons you stated that it is so easy for people to get trapped in limited ideas, so it is natures way of giving us a way out.
I think it has more to do with our metabolisms, but ok. :)
A changing of the guard if you will that eventually allows new ideas to enter and allows the religions to fall away and be replaced by new ideas.
I pray to the Sacred Spaghetti that this day may come sooner rather than later!
Whatever happens, I certainly plan on moving to Sweden before I start a family - they have one of the only school systems I would consider putting my own children through (pretty much anywhere else I'd homeschool). They also have a lower mindvirus infection rate than most other countries. ;)
