If the Flynn effect has ended in developed nations, then this may possibly allow national differences in IQ scores to diminish if the Flynn effect continues in nations with lower average national IQs.

When modern IQ tests are devised, the mean ( average ) score within an age group is set to 100 and the standard deviation ( SD ) almost always to 15, although this was not always so historically.
