Since the first findings about breastfeeding and IQ appeared a decade ago, many formula makers have added DHA and AA fatty acids to their products.

This translates to "cited study is obsolete, new study needed".

Expected result = if DHA and AA were the main causal agents for the difference, and they have been introduced to formula food, the difference should be much reduced (extent of reduction being contingent on the existence of other causal factors).

I'd say it translates more to 'investigate DHA/AA addition to formula and see whether it is anywhere near as much as breast milk or if it is just another cynical marketing ploy where trivial amounts are added to allow a popular claim on the label'.

For human breast milk, the median concentration of polyunsaturated fatty acids - including both DHA and AA - is given as 588 mg / 100 ml, subject to fluctuation. [1]

The local topselling Amazon baby formula contains 800 mg / 100 ml, closely monitored. Feel free to check your local products.

There are supplements that can be added if you want more, those are trivial molecules to manufacture and store.

Cool. Is there much variation between baby formulas - are the unpopular ones worse?

Do you mean in regard to these nutrients, or in general? In general they vary quite abit in composition and price. Though for all I now DHA & AA are constant (though I'd doubt it, given most parents aren't going to bother to look for it, ime).
