Alas, not so.
The fact that Jennifer filed this under ‘Humour’ and posted it on April 1st should have been a giveaway.
The references to Irving Janis are entirely accurate, and that, along with references to real people such as Vaclav Klaus and William Kininmonth give the blog post a high degree of verisimilitude.
I knew it could not be true when I got to this: In order to avoid groupthink the United Nations Secretary-General, Ban Ki-moon, has accepted the recommendation from President Klaus in particular that the IPCC adopt Janis’ nine principles including that several independent groups work on the same problem, that alternatives be properly examined, and at least one member of every working-group be assigned the role of Devil’s advocate.
Would that it were so!
Well done, Jennifer, and thanks for the laugh.
