Possibly parent is assuming that because IQ is a distribution with 100 at the center, any movement results in a shift of that median.
Potentially you could interpret this as suggesting a tacit (mathematical) increase elsewhere, but I don't think the math works out like that.

There is in fact an upward trend to IQ scores: When IQ tests are revised, they are again standardized using a new sample of test-takers, usually born more recently than the first; the average result is set to 100. When the new test subjects take the older tests, in almost every case their average scores are significantly above 100. https://en.m.wikipedia.org/wiki/Flynn_effect https://en.m.wikipedia.org/wiki/Flynn_effect
