Hmm. Would I be wildly wrong in describing Mrs Bennett (Elizabeth's mother) as a terrible narcissist though? In which case Elizabeth should be more likely to be a narcissist herself, or a people-pleaser? Maybe she got lucky, because she's hardly either. Although her sisters, well...

Good fiction often rings true to real life, but it's no more than a bit of fun to analyse it as though it were a case study of something that actually happened. Still, I'm not against fun. I bet it was fun for Jane Austen to write the character of Mr Collins. Let's see your science explain him ;)
