How to figure out what genre you should write
The quiz gives you an answer in two minutes. What follows is the longer version, drawn from the working routines of the authors on this site, because the question of what to write turns out to be answerable from evidence rather than instinct alone.
Start with what you reread, not what you admire
Most writers can name the books they think are important. That list is usually a poor guide. The more useful list is the one you return to when nothing is at stake: the books you have read three times, the ones you finish at two in the morning knowing you have work tomorrow. Admiration points at the writer you think you should be. Rereading points at the machinery your brain actually enjoys running.
If those two lists disagree, the rereading list is the one to trust. Plenty of literary writers privately reread crime novels, and the tension usually shows up as a strength once they stop resisting it.
Notice which problems you find interesting
Genre is less about subject matter than about the kind of problem you want to spend a year solving. Agatha Christie was solving a construction problem: how to hide a fact in plain sight and still play fair. Toni Morrison was solving a problem of interiority and history, and how much a reader can be trusted to carry. Neither would have enjoyed the other's puzzle.
Ask what you find yourself explaining to people at length. That subject is usually where your attention already lives, and attention is the resource a book actually costs.
Your genre has to survive a bad week
Every routine documented on this site was built to keep working when the writer felt terrible. Stephen King writes 2,000 words a day including holidays. Lee Child starts a Reacher novel every September the first. That kind of consistency is far easier when the material itself pulls you back to the desk.
So the honest test is not which genre sounds most impressive at a party. It is which one you would still open on a Tuesday in February when the draft is going badly and nobody is waiting for it.
The result is a starting point, not a verdict
Writers move. Kazuo Ishiguro has written a butler's memoir, a detective novel and a fantasy quest. Ursula K. Le Guin worked across science fiction, fantasy, poetry and essays for six decades. Learning one genre deeply is what makes crossing into another possible later, because conventions stop being rules and start being tools.
Treat your result as the place to build the habit first. Once the routine holds, the genre can change around it.
