経営者の素養に関わる話題が続きます。今回のチャーリー・マンガーも、少し前のウォーレン・バフェットとそっくりなことを言っています(過去記事)。以前に「誤判断の心理学」で「(その12) 自尊心過剰の傾向」をとりあげましたが、その際にご紹介しなかったくだりです。(日本語は拙訳)




Excesses of self-regard often cause bad hiring decisions because employers grossly overappraise the worth of their own conclusions that rely on impressions in face-to-face contact. The correct antidote to this sort of folly is to underweigh face-to-face impressions and overweigh the applicant's past record.

I once chose exactly this course of action while I served as chairman of an academic search committee. I convinced fellow committee members to stop all further interviews and simply appoint a person whose achievement record was much better than that of any other applicant. And when it was suggested to me that I wasn't giving “academic due process,” I replied that I was the one being true to academic values because I was using academic research showing poor predictive value of impressions from face-to-face interviews.

Because man is likely to be overinfluenced by face-to-face impressions that by definition involve his active participation, a job candidate who is a marvelous “presenter” often causes great danger under modern executive-search practice. In my opinion, Hewlett-Packard faced just such a danger when it interviewed the articulate, dynamic Carly Fiorina in its search for a new CEO. And I believe (1) that Hewlett-Packard made a bad decision when it chose Ms. Fiorina and (2) that this bad decision would not have been made if Hewlett-Packard had taken the methodological precautions it would have taken if it knew more psychology.
