is another one and i'll tell you i talked to one of the guys who was inch it was part of the m.c.i. carlton for many years ago. and he told me that when he started a counting fraud. his part of it wasn't the whole thing but his part of it it had nothing to do with his personal benefit for the company now the company is a big entity but he felt that this was he was under tremendous pressure to improve benefits accounting software was very fuzzy he didn't really realize what the rules are and what the regulation where something can stop and when can you just book some income for the future and know then say you're going to get it and so on and all of a sudden he basically used this flexibility to hide law to lots of money with out any personal benefit because he was part of the company he was working for the company so our ability for wishful thinking wishful blindness being part of a team is incredibly strong and because of their dictating the rules externally it's very important we can't expect. people who are inside the system like all that goes to be able to overcome all their biases. so
