In general, after reading the article... yeah it has basically the exact flaws I was expecting. It's actually pretty audacious they gave it the wording they did. I'd guess this was admitted more on the "editorial" side since it's not actually showing so much what it they suggest it's showing.
Since they're comparing results on an IQ test with actual real life decision making. (When iq tests aren't really a great measure of anything.)
As if not being able to think clearly under stress and make word associations with similes is going to be the same thing as not deciding to save money or pay a bill or something like that.
Had they wanted to run that kind of experiment they could of did a much more accurate study.
That stress = harder to think... should be basic psych 101. The way they tried to get around such a thing is to suggest that stress has no mental aspects. Only physical ones....
and that was it really.
So for example, say your stressed out for a different reason, you are afraid somebody is going to jump you after the test because somebody said they were going to jump you.
The thoughts of said person in your head jumping you? That doesn't count as stress at all!
After getting my girlfriends opinion she more or less just boils down the whole thing to them being psychologists blinded by positivistism.
