Between 2005 and 2015 the maximum score was 2400 instead of 1600. Assuming anyone who got <1600 during that period wouldn't admit it, you now have three well defined buckets.
But of course this is a lot of unnecessary steps compared to the usual method: length of work and education history +18 years.
Hah, you did the one at 12 also? I too remember both, and it was also 30 years ago. I don't know why, probably because they were really important numbers to teenagers, and they say you remember things that happened to you as a teen more than any other part of your life.
Sneaky age filter? You must be young enough to remember your SAT scores.
I can remember mine just fine.
If you're really looking for smart people, use "Answer this word problem in two or more paragraphs. Write your answer on the sheet of paper provided. In cursive."
Are people who were forced to learn cursive smarter? They're just older.
Doing this may well expose you to age discrimination lawsuits, since it's just sneaky indirect age filtering.
Another example would be if you required a minimum SAT score of 1601. Sure, someone could have gone off and taken the SAT as an adult or a young child but in reality it is mainly an age filter.
Are people who were forced to learn cursive smarter?
By definition, people who know more things are smarter than people who know fewer things. That's just how it works.
For centuries, people have striven to improve themselves through the acquisition of knowledge and skills. It is a quirk of recent generations that so many members take pride in their lack of knowledge.
I'm repeatedly bewildered by my Millennial colleagues who proudly say "I don't know what that means," or boast "I don't know what that is" with no sense of shame.
Imagine, you have two people. Person A knows cursive, person B does not. Person B knows the ins and outs of Newtonian physics, person A does not.
Which person is smarter? Which person would the cursive test say is smarter?
What you seem to have mistook for people not knowing things without shame, is people valuing knowledge not by the preponderance of its quantity but by its total when multiplied by its utility.
Otherwise I do not envy the shame you must feel at lacking the knowledge of which plants are edible, how to.clean a carcass, how to fashion a needle from bone and an axe from stone, the mixture of clays to use to make your bricks, and all manner of other once-necessary tidbits whose usefulness has lapsed for the general population.
The signal being that the smart people will refuse to jump through this hoop in your inane process because they have a lot of other opportunities to choose from.
I learned in Brazil. Here in the California I asked my son's kindergarten teacher if she would teach cursive, and she said they don't teach calligraphy and I've never seen it described this way, but she's right.
