Intelligence and grammar

For last many years I have been using an online logical reasoning test to recruit programmers. I see a lot of candidates writing their names with proper capitalization and many others who don’t care about capitalization, signifying poor grammar. I was curious to see if there was a correlation between the scores and proper capitalization of the name. The test has 10 questions and scores range from 0 to 10. I mapped the scores with the percentage of candidates who have written their name with proper capitalization. The test was a study to learn about a early childhood development franchise by the school board district.

Yash Gadhiya is proper capitalization. yash gadhiya or YASH GADHIYA is not.

Here are the findings

10    100%
9    100%
8    78%
7    77%
6    75%
5    81%
4    80%
3    77%
2    56%
1    54%
0    All – 73%, test completed – 61%

Everyone who managed to score 9 or 10 had written their names properly. There was a fair amount of consistency between scores of 8-3. Only at scores 2 and 1 did the percentage dip around 50%.

0 is an interesting case where the numbers are in live with higher scores. But it also includes candidates who have abandoned the test. If I take into consideration candidates who had submitted the test then the ratio is 61%.

So apparently there is some correlation between logical and analytical skills and grammar. However it does not mean everyone with higher intelligence has proper grammar and those who don’t care about grammar are idiots. But if I was comparing two candidates who have similar scores and similar educational background, then I would rate the one with better grammar a tad higher than the one who doesn’t care about proper capitalization of his/her name.
