When a problem is new and fresh for each participant, pairing can be a great tool to connect with both the problem and each other's innate skillset, IMO.
If you had the choice understand the concept 10 times slower but in the end would come up with twice the amount of connections, would you consider it as something valuable?
Yes I see how it would make life easier, but is that really a meaningful goal?
And how do we know that the reasons behind that it makes life easier isn't just a bias society has towards its own traits? - E.g life is easier for right handed people aswell.
You are right, species are discovered when in reference to our defined concept of what it means to be a spiece, that is a structure with all other spiecies. However it's name is an invention, as all definitions are invented.
Yes the song example can be put on a scale, but even the most plagerised of works can call it an invention to an extent when referencing a newly created title.
On a side note, since we all share the most primitive source of information, all behaviours are indirectly stolen on one level or another. But that idea doesn't contribute alot of practicality
If you reference it to the world and its inherent chaos it is an invention. If you reference it to a structure with labels and a finite number of alterations it is a discovery of a part of that structure
