I think you may well be correct in your assessment. Culture doesn't change overnight, and it's also inherited so may well have persisted to the present day. It also doesn't change without external pressure, and only reluctantly even then. I've seen different cultures in various labs I've worked in or had contact with, and it can vary wildly from being extremely disciplined to extremely sloppy and both practices can be picked up by new people from the individuals concerned.
