In a 2004 article entitled Groups of diverse problem solvers can outperform groups of high-ability problem solvers, L. Hong and S. Page argued that "diversity trumps ability" and provided a mathematical theorem to support their conclusion. In his 2007 book, Page added that "$\ldots$ the veracity of the diversity trumps ability claim is not a matter of dispute. It's true, just as $1+1=2$ is true", apparently referring to the said theorem.
In a 2014 article Does diversity trump ability?, A. Thompson provided a counterexample to the theorem of Hong and Page. In a subsequent exchange of letters, Hong and Page pointed out that Thompson missed a hypothesis that bars Thompson's counterexample, and Thompson retorted that the hypothesis was not given in the 2004 article.
All this surely boosts readership but it still leaves the purely mathematical and therefore educational question unanswered: is there nontrivial mathematical content to the Hong-Page theorem (once all the hypotheses are in place, that is)?
