I'm never sure whether I should be amused or horrified by how much business writing tends to run on sentiment and emotion rather than empiricism.

It seems to be more about Management Feels - up to Board level - and not so much about learning how to get things done.

If you can sell a combination of subtle narcissistic flattery with enthusiastic promises of predictability, control, and guaranteed success your books will do extremely well - even if the advice is simplistic harmful nonsense.
