Indeed. Economics is the art of using meaningless spreadsheets and number-crunching to justify the decisions you were going to make anyway. Oster's book is a great example of how.
It sounds like you’re getting mad at someone for reading Malcolm Gladwell or Freakanomics. It might be NYT bestseller middlebrow pop science that you find facile and contemptuous but a lot of people do not. And the author doesn’t even indicate how Oster informed his parenting. Seems overly dismissive of the article.
This is pretty disingenuous. Oster's book(s) is tantamount to long-form data journalism, principally citing research to criticize confidence in certain notions rather than arguing for overconfidence in another.
Much like nutrition and sociology, research can be politically fraught, have lots of data points, etc. But that's neither here nor there, either research is high quality or it isn't, including in the domain of economy.
