Who is assuming anything? People are conducting science and the evidence doesn't support an advantage for this particular function. Also, not only do I not think it is not absurd to consider that maybe a second language does not offer any significant advantages, I also think it's a possibility that learning more languages than one could be harmful overall. To assume anything else without supporting evidence is showing a bias.
