they slightly increase it to keep the average around 100

They don't "slightly increase it to keep the average around 100." The average is defined as 100. https://en.wikipedia.org/wiki/Standard_score https://en.wikipedia.org/wiki/IQ_classification

My explanation is for laymen, 100 in 2025 is not the same 100 in 1925, my point.

Lots of people who talk about IQ don't know what the Q stands for.
