What is "second-level thinking" in The Most Important Thing?

Second-level thinking requires deeper analysis than surface-level conclusions. For example:

• First-level: A rising stock suggests buying.
• Second-level: Assess whether the price already reflects optimism, making it overvalued.

Marks argues this approach helps identify mispriced assets and avoid market traps.
