The Dangers of Marginal Thinking
Christensen emphasizes the dangers of marginal thinking, where individuals justify small deviations from their principles with the thought that it’s just a one-time exception. This mindset can lead to significant negative consequences over time. He uses the story of Nick Leeson, a trader who brought down Barings Bank, to illustrate this vividly. 'The costs of taking the high road are always clear like that. But the costs of taking the low road—the one Leeson took—don’t seem that bad at the start.'
