I think that in this case, scientists would have to confront Jeff to situations provoking big reactions from him and then do the same thing with the simulations to see which one is the real Jeff. It includes, for some people, to go beyond the limit of ethical actions to simulate Jeff considering you have to make him react to stressful situations like near death or pain without him being aware of it, just enduring it and reacting to it his own way.
Basically, in this case all you need to simulate someone is past events to refer to. It is true this method has...
I don't think we can quantify this pattern.
I see a solution to your problem but it may include a form of torture for the "other you".
Let's say you created a simulation of you, with some kind of feelings cursors you can modify ( humour : 77% - love : 56% for example ).
You, as a human, have a past and I will assume that you took that fact in count when creating the simulation of you, meaning your other " you " has memories etc... it isn't a simple you from the present, you can also simulate the 16yo " you " and se...
Maybe exactly copying a Jeff is impossible, in fact I don't think we know all the personnality aspects someone can have so for now this task sounds difficult.
But in my opinion, if " Sim-Jeff " reacted to the same situation 2 000 000 times but with microscopically differences, it is pointless to keep that detail in mind. As a human being, you can't perceive those little behavior differences so it is useless to give them importance.
For example, Simulation n°1 320 678 SimJeff is scared and takes a 1 foot step back, Simulation n°... (read more)
