Another twist to the demographic crisis - it’s not only that ‘dependency ratio’ irreversibly declines, but also that the people who are left in work seem to be less innovative. This is because younger people have more ‘fluid intelligence’ compared to older people with more ‘crystallised intelligence’, a thesis which has strong evidence from neurobiology, yet one which has difficult implications for TA / HR. Have a read of this, and see if we can oscillate between fluidity and rigidity of thinking.
