I'm a statistics student at the undergraduate level, writing an undergraduate thesis about genetics. I already have the objectives well defined and I will write the introduction lined with those objectives.
I found a text in a website with authors name and publication date that would be nice to put in my introduction. Is a bad thing start an introduction with a citation?
EDIT: Is a direct quote.
While I am not aware of any hard and fast rule against it, I would find it off-putting to read a scientific document that started its prose with a direct quote. There are just so many ways to start with one's own words that it feels lazy and lacking in self-confidence to me to use another's words for the first impression of a reader.
Note, however, that I am speaking of using a quotation as the first piece of one's prose, as distinct from the practice of putting a separated "thematic" quotation at the start of a document of chapter. I see this somewhat more often, and though I find it a bit "cute" in scientific work, I don't have a problem with it the way I would if somebody starts their prose with a quotation.
