She's since gone into the value of information, how some ("the chemical plant is about to explode unless you shut part N down") is more valuable than other ("Jim worked 2 hours of overtime"), and how costly incorrect information can be.

She used the example of a personnel database and how incorrect information could lead to negative outcomes for people, who have a right to sue over it.

I can't help but extrapolate to *mis*information, wilfully incorrect information that can have extreme costs.
