What about people who ace standardized tests, but are open to "conspiracy theories"? Just outliers? I've seen a couple.
This sounds similar to standardized tests like the LSAT
There's a whole plethora of them, ranging in difficulty, appropriate age and the amount of critical thinking they measure.
In fact any test given to a group of people can be considered a standardized test. But very few of them measure any sort of critical thinking, or even reading comprehension.
