Congratulations on demonstrating you've never read a single scholarly psychology article and possibly never a single scholarly article.
Cognitive psychology can get highly consistent results in experimentation done with rigorous controls. The conclusions drawn from these results may vary greatly (see the systems vs. processing debate) but that is the same with every field. "Asking a person a question" is hardly an example of experimentation. Room for variation exists in the reception of the question, the processing of the question, the output of the question, and the reception of that output by a researcher.
Parts of psychology research are on the outer limits of what can be considered "pure" enough to be science, but other parts like the aforementioned cognitive psychology are quite scientific if not as pleasantly quantifiable as chemistry and physics. However, the publications themselves are often the first to point out the generalizable limits of their results.
