ワイルド先生、“Teamology”出版のお知らせ

　2006年6月、スタンフォード大学からワイルド教授をお招きし、御出講していただいた第40回懇談会(

) を覚えておられるだろうか。その時の話題、『性格診断を使った成功する設計チームの形成』が本にまとめられ出版された。ユングの認識論を元に確立されたMBTIを利用して、効果的なチームを作り、実際その効果が世界的に立証されているという驚きの講演だった。
　MBTIとは、その発案者達の苗字を頭に置いた言葉、Myers-Briggs Type Indicatorを略したものだが、マイヤー･ブリッグスの性向指数とでも訳せばいいだろう。アンケート形式の質問表に答えると、その結果より回答者の性向がわかるというものである。
　MBTIなど、ユングの性向タイプについて研究、事業を行う組織は数多くあるが、その中の"Center for Applications of Psychological Type"による "Journal of Psychological Type"に、昨年10月から今年1月にかけて Reynierse と Harker による論文が発表され、アメリカで話題になっている。統計解析により、MBTIの結果に有意差が認められなかったというのだ。この業界にとっては激震が走ったと見るべきだろう。
　このユングの性格タイプについて、唯一数学的アプローチを行っているのがワイルド先生である。そして今、この数学的分析が注目を集めている。
　第40回懇談会(

) のワイルド先生の講演を受け、その内容は論文にまとめてあるので、興味ある方は是非読んでみよう。

本記事最後にワイルド先生との交信記録を記しておく。本の出版に先立ち、どのようなやり取りがあるか、英語、そして数学に自信のある方には一読をお勧めする。

I see you are drawn to the combinatorial optimization aspects of this team business, Kenji. I myself can't imagine a single measure of effectiveness of a team formation plan. Personally I just look to see how many teams have to "reach" for some modes, a rough criterion used in the Ch. 4 discussion of the evaluation of team formation plans (p. 8). I also think any measure of effectiveness should be based on cognitive modes rather the MB variables.

A technical point: the transformation from MB 4-space to modal 4-space is "homogeneous" rather than "affine" because the origins map to each other. By the way, the transformation is "orthogonal" but not "normal". Length, which has no meaning anyway in this context, is NOT preserved under the transformation, so the transformation is not even Euclidean. I stumbled on this point when I put together the earlier theory that MM made into a web site for ME310. I had the site withdrawn when I realized the error, but I'm afraid YS did use the MM site in his research. I hope I talked him into correcting things.

Keep on truckin・
