One of the pitfalls of doing research is that although you may know a lot about your topic through extensive reading, it is hard to keep track of where you obtained bits of information. I have observed that it is easy to read and gain new information and ideas, but it is sometimes harder to recall where those ideas came from. This isn't generally a problem we face, but in research it becomes more apparent. As researchers, we have to provide citations for ideas that are not ours. This situation can be likened to a source memory error, which occurs when we incorrectly think that a recollected experience is the source of a particular memory.
