Still there might be variations in the ways of thinking. Mappers/packers sure is far from perfect but it is an interesting start.
There are plenty of problems that can be solved more efficiently the packer way.
I never claimed something different. In fact, what I tried to explain in my post is that all of us think "packer" way virtually all of the time. The "Mapping" is only setup, training, learning. The symptomatic difference between "Mappers" and "Packers" is not so much how their brain runs when they make decisions, but how they
learn.
I'm just saying that this is an important difference. The "Mappers vs Packers" model sounds as if "Mappers" would match their knowledge to a situation in a totally different way from "Packers". I don't believe that is correct; on the contrary, I think the difference during that phase is only very subtle.
The real difference is how they re-organize their thoughts and beliefs when they have time to think or are asleep.
Edit: Okay, I've been persuaded that the terminology might be useful despite the things I pointed out. There is a clear barrier from with a person starts consciously applying "Mapper" technique and therefore can learn with increasing efficiency. This creates an instability, which might cause people to fall into two distinct groups.
This instability might also explain the huge gap in logical capabilities between scientists and the average population. I know it by a different name, "the scientific method", I'm fine with using "Mapper thinking" as a synonym though.
