Why we love true crime — and how that passion may help our legal system

It's no secret that Australians have a growing appetite for true crime which is seeing us lap up series like The Teacher's Pet, TraceUnravel and Exposed: The Case of Keli Lane

A recent survey by the ABC showed almost half of Australian podcast consumers recently listened to true crime, with the trend strongest among women. 

But why are we so obsessed with these stories? And is that obsession helping us develop a deeper understanding of the justice system? 

RMIT University's Michele Ruyters, who was featured in Exposed, likens our want to solve crimes to the desire to finish a difficult puzzle or crossword.

"At heart I think people really love being detectives," she says.

"There's just something about the innate human curiosity wanting to look at a problem and attempt a solution."
