New Idea: Including alive people (with no info)
I think it would be beneficial to show people who are living.
These living people do not need to be identified as male or female, do not need to have any vital stats to be listed or any other information to be displayed. Maybe just displayed as "unknown".
The reason is because if a researcher is adding alive people to the system, only they are allowed to view these people. If other researchers working on the same line, decided to add the same people, there is no way to know how many identical profiles are being made.
However, I can see that this will still be problematic because researchers could still confuse the "unknown" alive people with other researchers creating the same "unknown" people.
