I think the most important thing to teach young people entering scientific and engineering careers today is “if they won’t put it in writing and sign it, don’t do it.”
That’s harder than it sounds. Lots of people can’t assert themselves to the necessary degree without significant training and practice. The majority of humans do what they are told; getting people to get up on their hind legs and say “boss, I can’t do that without signed, explicit direction” isn’t simple.
