I can think of one situation where pulling the levers would be more 'good' than 'bad'.

Estimate each of their future influence on others - both span and depth. If you consider it 'high', then pull the lever. If you consider it 'low' (which might further correlate with lower IQ), then (tentatively) hold off.
