Usually the public is only made aware of research findings after the research study has been written up and submitted to a journal, and has undergone peer review. During peer review the draft paper is usually sent to two or more researchers in the same field. If the reviewers are not happy with the quality of the research, they will reject the paper (often they will advise what changes need to be made). In peer review, the reviewers judge the scientific quality of the research (they are not biased by any personal issues). Sometimes the only thing that is "wrong" with the paper is that the focus of the research is outside the topic area of the journal. In these cases the researchers should submit the paper to a more appropriate journal.
The Differences between Science and Pseudo-Science.
The Scientific method is rigorous and based on observation, theory, experimentation, documentation, repeatability, and critical review. The underlying principles of Science: to observe, question, theorise, and test are quite different from pseudo-science, which begins with a preconcieved idea or theory and then looks for certain experimental results or evidence to support that idea, rejecting other contrary evidence in the process.
Making an observation -> making a deduction -> stating the deduction as fact before/without rigorous scientific testing
Making an observation -> making a deduction -> presenting the deduction as an unconfirmed hypothesis until confirmed with rigorous scientific testing
How does this relate to the J2 Y-DNA project?
The J2 Y-DNA project conducts its research according to the scientific method. The only manner in which the project differs from academic studies is that the DNA testing is funded by each individual test subject, and that preliminary results are made available publically (ie. prior to being conclusive as determined by rigourous scientific study/peer review).
At this time (July 2008), all the J2 Y-DNA projects findings are still in the process of being scientifically tested. None of the findings are ready for peer review yet. The research still needs to continue/undergo rigourous scientific study before it is at a stage where it would be considered ready for peer review.
