https://en.wikipedia.org/wiki/MultilingualismSome studies have found that groups of multilingual individuals
get higher average scores on tests for certain personality traits such as cultural empathy,
openmindedness and social initiative.[15][16]
The idea of linguistic relativity, which claims that the language people speak influences the way they see the world, can be interpreted to mean that individuals who speak multiple languages have a broader,
more diverse view of the world, even when speaking only one language at a time.
https://en.wikipedia.org/wiki/Eye_dialectEye dialect is the use of nonstandard spelling for speech to draw attention to an ironically standard pronunciation. The term was coined by George P. Krapp to refer to the literary technique of using nonstandard spelling that implies a pronunciation of the given word that is actually standard, such as wimmin for women; the spelling indicates that the character's speech overall is dialectal,
foreign, or uneducated.
Who are those "foreign" that will always make wrong spellings?
Russian,Chinese,African (languages),South Americans (languages) .
World is not "English" language, but indeed is using it as international communication.
In fact "foreign" should use multi language dialects and accents in order to spell something .
This doesn't make them stupid , but rather it makes them more intellectual than the ones that they use 1-2 Languages.
