How accurate is an intelligence test?

Intelligence tests are tests that have sparked controversy since their development. Many scientists claim that they are a way to approximate an indicator of brain function. On the other hand, other scientists claim that these tests should not be an indicator because the functioning of the brain is influenced by external factors that alter its functioning.

According to the above, it can be inferred that the tests performed on the subject are not valid because his results are very different in each of the tests, so they cannot accurately indicate his intelligence index.
