Why is 'second-level thinking' crucial for investors?

Second-level thinking is crucial because it allows investors to move beyond obvious market narratives and common consensus to identify mispriced opportunities. Instead of just noting a 'good company,' a second-level thinker asks if that company's perceived goodness is already priced in, seeking deeper, less obvious reasons for potential outperformance or underperformance. This nuanced perspective helps avoid overcrowded trades.
