It's pretty simple to assume what pseudoscience means, right? "Pseudo" means fake, and "science" means, well…science. I didn't need to consult a dictionary for that. I decided to obtain a working definition of the word pseudoscience because upon going to use it, I realized I had only my personal interpretation of the word to draw upon, which I wanted to assure was correct and not skewed.
I will say that in the argument over pseudoscience, all roads lead to falsifiability. In general, any statement can fall into three categories:
1. A statement which is falsifiable, but has not yet been falsified;
2. A statement which is falsifiable, and has been shown to be false;
3. A statement which is not falsifiable.
Put simply, unfalsifiable statements or falsifiable statements that have been proven false are not scientific statements. For this reason, I currently don't think that creationism or intelligent design qualify as scientific ideas. There might be an isolated component in any form of either idea that is falsifiable, however. For example, the various forms of the moon-dust argument.
