It is demonstrated that speaking a specific spoken language induce some representation and reflect cultural habits and biases...
Speaking many languages will not mix up your brain not fuck it up at all it will only change it for the better..😊
As in music a Bossa Nova culture exist which is different than Protestant Netherlands culture of the organ and harpsichoed playing or different from the Veena culture of India..
Listening them will not mix our brain nor our identity...
But this does not means that these culture deep biases dont exist for a deep reason too ...
Then you joke is very good one...😊
But culture and science cannot be reduced to a joke so good it was ...
Human nature is universal but deeply rooted in some soil under some sky and link people to one  another by subtle ecological and body rythms; and speech habits reflecting them and growing from them ... An antartic inouk is not some jungle brazil tribe with no perception of number but who can whistle their language...I guess their music and relation to their environment and trained biases as innate biases are different and tweaked for their survival...
😊
OK something about bias and national:
I really prone to pick-up tunes from Bossa Nova, Tango and Gypsy Jazz.
That brings me an idea that I could be mix of Brazilian and French origin and forget about where I was born LOL!!
