Hi Nick,
LOL! It would take days to reply to all of your questions! But I can direct you to articles that will answer some of them.
First, I suggest that you check out the other articles in the National Leaders series, starting with National leaders’ thinking: How does it measure up?
Second, you might find it interesting to take the FOLA, a course about the evolution of the Lectical Assessment System that we used to teach at Harvard.
And third, you could learn more about how Lectical Assessments are made by checking out our methods pages.
Happy reading!
