|Alfred Binet, I have no idea what this contraption is.|
There are many factors to consider when evaluating a questionnaire or a test. Testing in psychology and education has been big business for over 100 years since Alfred Binet (seen above). WWI was the first time that large numbers of young men were given intelligence tests like Binet's and 40% were classified as 'feeble minded' as were around 80% of immigrants at Ellis Island. Revisions were made to the test and it has been big business ever since.
Getting back to Froth's question I need to consider these and other issues such as how does the item about God fit in with the other test items and how exactly is it worded before I can answer his question. This may be more than Froth wanted to know but this is the world of psychological testing.
Albert Einstein asked the developmental psychologist Jean Piaget at what age children understand space and time. Piaget responded by writing several books on the topic.
