All young men in Norway |
| [00:02.622] |
must take a test of their cognitive ability at age nineteen |
| [00:07.557] |
in preparation for required military service. |
| [00:10.862] |
This is commonly called an IQ,or intelligence quotient test |
| [00:16.842] |
The researchers compared the test results of one hundred seven thousand young men |
| [00:23.35] |
to their years of school. |

TARYN ANN GALLOWAY: |
| [00:32.841] |
"The young men who were basically forced to stay in school |
| [00:35.491] |
for two years longer actually did have higher IQs. |
| [00:38.15] |
So,based on that, |
| [00:40.50] |
we were able to say that increasing compulsory schooling |
| [00:42.530] |
did actually have an effect on their cognitive abilities as measured at nineteen years of age." |
