This is why blameless postmortems are such good thing.
Going one step further having a culture where finding a bug or defect in your own code/design is rewarded makes it so people aren't afraid but excited to talk about them.

100%. I'm very much a fan of asking _what_ happened and then figuring out how to prevent it from happening ahead. Look back to inform the future, not to find blame. Ultimately, if 1 person can blow things up, it's a bigger issue at play.
