I suppose I must not be very smart considering I speak 3 languages.
That all depends on the neurological study you are referencing. Newer research points in that direction that being multilingual does not have an impact on overall intelligence because language skills come from the parietal lobe of the brain. The frontal lobe is where reasoning and problem solving skills (also known as fluid intelligence) come from which is what IQ test measure. Currently the IQ test is the standard.
There is the parieto-frontal integration theory that proposes higher intelligence comes from better communication efficiency between several areas of the brain including the prefrontal cortex, parietal lobe, anterior cingulate cortex, and other specific areas of the brain. I personally like this theory because it gives a better picture of how parts of the brain work together to produce intelligence. But this theory gives rise to measuring intelligence in how efficient each part communicates with each other, not a measure of each part individually. Which somewhat goes back to the original point that being multilingual does not automatically equal more intelligence.
You keep saying you have a hard time understanding a simple writeup in English which is not in your native tongue... ever hear of google translate? Why don't you take the writeup, drop it in there, then read it in your native language? Between google translate or any other programs available it shouldn't be that hard to get a good translation. Seems more like a comprehension and reasoning problem more than a language problem to me.
You can respond with whatever snarky comments you like, but I grow tired of your nonsense. I will only be replying back to this thread if it pertains to the original subject.
I apologize to the OP for being part of the reason this discussion got off track. Hopefully you were able to get the advice you needed before things went off the rails. If you need further advice I will help where I can and do my best (and hope everyone else will too) to keep my responses to the topic at hand.
