“The problem is that if the person then says I would rather go home and finish the job tomorrow, they start to feel guilty. Their Chimp is now saying, ‘You can’t let the troop down, what will they think?’ Well as we now know, it isn’t the troop at all. It is work and work colleagues. Looking after the Chimp by getting it home on time and looking after the real troop is more important than working to please work colleagues.”
