Data, big and small

Alex Peysakhovich and Seth Stephens-Davidowitz write in the NYT about  How Not to Drown in Numbers, about how you can't always interpret data in a dataset just by looking at the dataset in isolation...

"So what can big data do to help us make big decisions? One of us, Alex, is a data scientist at Facebook. The other, Seth, is a former data scientist at Google. There is a special sauce necessary to making big data work: surveys and the judgment of humans — two seemingly old-fashioned approaches that we will call small data."
