IQ score is based on an average. A person of average intelligence gets an IQ score of 100. If the population is 'dumbing down', you would still see the same number of people with an IQ of 100. If we're seeing more people with lower IQ, this means the bell curve of IQ must be widening, and so we must be seeing either; i: more people with higher IQ's; or ii: The top 1% getting higher.
