Could you provide an algorithm for deciding how many children to have? Then could you apply it to an average American family in 1950? I bet that any algorithm would tell them 'Are you crazy to even consider having kids? You just witnessed a global war that took tens of millions of lives. The world economy is still anemic. And the world is on the cusp of the nuclear war.' And every algorithm will be proven wrong by the baby-boomers generation. I think your argument is a suggestion to over-rationalize in the absence of information. Exactly what the article is describing.
