The link between truth and scientific fact is stronger than personal belief, mostly because belief is inseparable from personal experiences and science strives to be completely isolated from the person doing the experament. We have seen bad science frequently these days (both sides of the global warming debate need to step away from the politics verrrrrryyyyy slowly) and it's giving it a very wishy-washy appearence. This is not real science. The express reason for requiring that all experaments be recreatable is to eliminate personal bias and error, and ensure that the data holds true
for the defined set of circumstances. Behaviors are truths, matter will always exert a force on other matter, light will always propogate in a predictable fashion as long as you know the properties of the surrounding space. The only things that changes based on perception are people. It's not your surroundings that change, it's you.
The most basic reason I don't like the word truth used like that is that it takes all meaning away from the word. It's like saying "I'll love you forever", you won't be here forever but using a strong word puts emphasis on the intention. What we experience are not individual truths, just perceptions that are so important to us that we call them truths to emphasize how strongly we adhear to them.
p.s. quantum mechanics does not apply as long as you have more mass than an electron. don't go there. please
