Seems like "invalid" or "inauthentic" is meant.

I think that your problem was that you actually knew what the word meant. I just looked it up, and found that I didn't. I knew it was something bad, though -- I only see it in polemic. I think that there has been an extension from "ad hoc special pleading", which is the polemical use of the word I'm familiar with.

OED's meaning number 3 for factitious is "Got up, made up for a particular occasion or purpose; arising from custom, habit, or design; not natural or spontaneous". This can fit, I think.

In that context I feel like it isn't the established word factitious, but rather a new one meaning "half-factual, half-fictional". You know, like "mockumentary".

I think she meant something closer to 'fabricated', but was influenced by 'fictitious' and probably thought that factitious was just a suitably fancy way of saying that. Perhaps she even meant 'fictitious but fact-based'. Once you get way out there on the skinny part of the limb, who knows?

I have seen this happen in other places with the same word. At least, that's what I think happened. When you're writing a review for the New Yorker, hey, any extra pretense is good wherever you can get it, I guess.

I think it's becoming more and more socially unacceptable for people to admit that they don't know what a certain word means. Nod and smile, but dear god, don't actually admit that you don't know. So we end up with these words, used in their proper context elsewhere, picked up by people -- writers who don't ever open dictionaries, I guess -- and used in situations like this one.

I've probably done it myself, but I try to look up definitions. I could understand not looking things up if it was a big hassle, but we have this here interweb thing now.

Another vote for the "half-factual, half-fictional" interpretation. When I read the paragraph I immediately wondered whether it was a deliberate piece of wordplay -- fictitious but with a leavening of fact.

From the context, I read it as meaning that the work is "faction" - as Matt says, fact and fiction mingled (like mockumentary). However, I can't see why Cusk should link it with "breezy complacency", unless she's somehow bringing "facetious" into the mix too.

Yes, it was the "breezy complacency" that threw me completely off the rails. Thanks, everyone, for a very illuminating discussion!

I took it as the half-fact, half-fiction also, or perhaps as docu-drama.

Ray, you've summarized contemporary literature:

... fact and fiction mingled (like mockumentary) ... somehow bringing "facetious" into the mix too.

Is it possible the reviewer meant "facetious"?

Context would suggest that 'factitious' refers to something which is fictitious, but which is ultimately based on fact. The character in question appropriates factual events from other people's lives and presents them as coming from her own.

I'm thinking it's just a typo.

A typo for what? "Fictitious" doesn't work any better in context. Furthermore, if it were a typo you'd think they'd have fixed the online text, as the Times did with the Sontag quote in the Addendum.

The word "factitious" posed a problem for Esther Greenwood in Sylvia Plath's Bell Jar. Esther's creative writing tutor scrawled the word on a short story she wrote; she didn't know what it meant and had to look it up. The meaning Plath gives, if I recall correctly, is "artificial, a sham".

It has ben said before. "I read the newspapers avidly. It is my one form of continuous fiction"

Dictionary.com gives:

"Sham" in particular seems to make sense in context.

yeah, journalists are leading the way to make "factitious" a kind of derogative, in the same way they have made "substantive" a meaningless intensifier. welcome to the TWENNY FIRS CENCHRY!
