Everyone is entitled to their own opinion, but not their own facts. We try to bring you the facts, to help you form your opinion. We try to stick to the facts, and let others debate opinion.
Knowledge is often power, and it is therefore often helpful to be aware of a broad universe of conflicting results or conflicting opinions rather than having a portion of this information arbitrarily censored by someone else. Frequently one wants to know of the existence of information, even if one later decides not to use it for a particular application. Many would like to see a high percentage of the information available and decide for themselves what to throw out, partly because they don't want to seem uninformed or be caught by surprise by potentially important information. They are in a better position if they can say: "I knew about that data, assessed it based on the following quality assurance criteria, and decided not to use it for this application." This is especially true for users near the end of long decision processes.
Like a library or most large databases, this website contains information of variable quality from quite diverse sources. In compiling this website, mistakes were found in peer reviewed journal articles, as well as in databases with relatively elaborate quality control mechanisms. A few of these were caught and corrected on this website, but undoubtedly others slipped through. Most likely additional transcription errors and typos have been added in some of our efforts. Furthermore, with such complex subject matter, it is not always easy to determine what is correct and what is incorrect, especially with the "experts" often disagreeing. It is not uncommon in research for two different researchers to come up with different results which lead them to different conclusions. In compiling this website, we have not tried to resolve such conflicts, but rather simply reported it all.
This website is compiled by human beings, mostly by compiling or summarizing what other human beings have written. Therefore, it most likely contains some mistakes and/or potential misinterpretations and should be used primarily as a way to search quickly for basic information and information sources. It should not be viewed as an exhaustive, "last-word" source for critical applications (such as those requiring legally defensible information). For critical applications, it is best to use this document to find sources, and then to obtain the original documents and/or talk to the authors before depending too heavily on a particular piece of information.
