In one sentence: A rerun of 275: Phil and Danielle discuss why a professional like Ackman strayed from his own checklist (arrogance about what he understood), whether boards of directors are worth studying, and how to use the eight items as a check that a company's story hasn't changed.

    AnswerHe believed harder businesses met "simple and predictable" without realizing what he didn't know.

    AnswerSpend a couple of hours to see if the board is an outlier, and dig further only if it is.
  3. How can the checklist help after you buy?
