Imagine you work as an aerospace engineer. Imagine having to couch/overthink everything your say in communication so that it can't be taken out of context later. You literally have yearly training on how you have to communicate and in hugely impacts how people work because one dumb one off comment in email can financially end the company when an accident occurs.

and that's before you get to the fact that you have to defer how your IT systems work to the lawyers from the big overseas insurance company that covers your company/products. It's a major pain to get them to sign off on collaboration systems because they are such a discovery risk not because you are hidings, but because of how people communicate especially around issues. As far as discovery goes with aerospace, if your engineers anywhere acknowledged any problems, you are hit. How can you have a good product/continuous improvement when you can't acknowledge issues in writing?
