What if you data are all invalid. Do you still want to make "data-driven" decisions?

@garyackerman I guess it depends on the alternative. I prefer date driven decisions even ones where the data is no better than random chance to decisions made based on what will move the most money into the pockets of the powerful. On the other hand if the graft is the reason the data is skewed, it is better to case lots than use it.
