What is the IQ scale based off of?
What difference does 1 IQ more make? or 10 more make?
Can it ever change over time or is it a creature’s/person’s own level of understanding rather than what they know?
In: Biology
IQ is calculated by comparing a score determined from how well you did on a specific test compared to the expected result given your age, so yes it will change over time. An IQ of 100 means you did exactly as expected. If you get older but don’t improve on the test, your IQ will decline. It should be noted that IQ was created to measure a child’s mental development, and children are expected to improve mentally as they get older. Once you’re an adult, of course, that isn’t the case. IQ doesn’t measure knowledge, it measures a person’s ability to think critically and reason in certain ways.
