Yes, I strongly assume that user is indeed Jennifer Lawrence herself. But I don’t think she will be a prolific Quoran. It seems that Lawrence will be just another celebrity (especially actors) that writes a few half assed answers about themselves on Quora for some little publicity stunt (via the Celebrity Undercover videos), and then they are done with it. If you take a look at her edit history, they all take place on one day a few weeks ago. She also hasn’t really upvoted any others answers at this point either. This strongly indicates that she lacks interest in using Quora.

Other well known film stars that previously have done similar stunts on Quora include Jackie Chan and John Boyega. Like Lawrence, they only wrote a few half hearted answers about themselves, and they never did anything else with their accounts. I doubt that Lawrence will contribute to this website beyond those answers.

Edit: I am shutting off comments for this answer. I am getting increasingly fatigued about explaining over and over again to some rather thin skinned Lawrence fans that this is not an attack on the actress. This answer is only meant to explain that her Quora activities are a one time occurrence. After receiving some rather nasty insults and personal attacks, I have decided to shut off comments. Plus, I really don’t want to get into online fights over an actress I am mostly indifferent about.
Thanks for reading: Is Jennifer Lawrence actually on Quora?, Sorry, my English is bad:)
