There was an article on HN a month or so I can't find a link to which discussed how a number of major banks didn't properly update their models to knowingly take greater risks. It explored how a number of banks were using outdated models to allow them to bundle risks to create short-term profits at increased risk without upsetting the feds. So, sure, the models were wrong but was the reason the inability of the modelers?
