the point i was trying to make is, that there might be "theories" that are considered pseudoscience because of the lack of scientific evidence,
Such theories would not be so considered by trained scientists and philosophers of science. If you look at the criteria I gave, you will see that classification of a theory as "scientific" and "not scientific" has nothing to do with gathering evidence[/color]. The judging of a theory is done solely on the basis of the claims made by the theory itself[/color].
Take string theory for example. It is by no means proven, as we do not have the technology to see if it is predictions are satisfied or falsified. Is it scientific?
Yes.
Let's look at the criteria again.
1. It must be consistent.
String theory is an elementary (albeit sophisticated!) mathematical formalism from which it is not possible to derive contradictory conclusions. Thus, it is consistent.
2. It must be valid.
String theory is derived from its base assumptions without resorting to any questionable mathematics. Thus, it is valid.
3a. It must be satisfiable.
The predictions of string theory are, in principle, accessible to experimental verification. While we do not yet have the technology to check whether or not the claims are in fact satisfied[/color] in nature, we do know that the claim is satisfiable[/color], and that is all that is required. Thus, string theory is satisfiable.
3b. It must be falsifiable.
The predictions of string theory are also such that, if one of them is found to be contrary to nature's workings, the whole theory is proven wrong. An example is the low-energy manifestations of the single, unified force. String theory correctly separates into the more familiar 4 forces at low energies. If it did not, then we could say for certain that string theory is wrong[/color]. Thus, string theory is falsifiable.
3. It must be contingent.
Because it meets both 3a and 3b, it is contingent.
Thus, string theory is scientific, even though it has not been adequately tested due to technological limitations.
I picked that one because it addresses your point head-on.
