SVT is the Swedish government news agency. The article describes a politician facing charges for suggesting that South Sudanese people have a lower IQ.
The original claim was that it is illegal to study or to publish on such a claim. For pure slander in a non-scientific context without evidence, sure, some countries prohibit that.
There's no empirical evidence that South Sudanese people, as a population, have lower IQ, therefore this cannot be interpreted as anything but an attempt to denigrate an entire people
No it highlights that a right-wing politician known for saying inflammatory things about migrants made a comment for purely political purposes and clearly did not care about the underlying scientific validity of his claim, since it actually does not exist.
Can you source that it is actually legal to say that an ethnic group of people have a lower IQ, in Sweden?
I live in Sweden, and can attest to my own knowledge of the law, whilst not being a lawyer, that it is not legal. Let alone, reasonably possible therefore to have these things published in a journal here.
