Little Hawk...Wolfgang answered the question of biased & prejudiced scientific research in his earlier post. The point was, it is self correcting. Even biased & prejudiced research can serve a purpose, when it is being done to counter OTHER biased & prejudiced research! And eventually, whether by honest research or biased research, some theory or set of facts emerge which are hard to challenge...and they remain until new data are found.....and so it goes. There ARE tenets of science which are NOT challenged much anymore, (i.e. 'the Earth is roughly spherical') because almost universal agreement has been reached.

as to 'faith'...it is like a number of concepts we argue about here regularly. It lends itself to equivocation, that is, using the word to mean something a bit different from either 1)what your opponent is talking about, or b) what the generally understood usage of the word is.
...it is done with 'folk', it is done with 'God', it is done with 'fair' and 'reasonable' and it is REALLY done with 'belief'....and when done carefully, equivocation is hard to catch and takes a LOT of typing to expose. It is related to the "straw man" argument, where someone mis-represents a position (whether accidently, or on purpose)in order to argue against it.
