For Big-Data Scientists, ‘Janitor Work’ Is Key Hurdle to Insights

This is the title of a new NYT article reflecting the view from then data trenches. It says “data scientists, according to interviews and expert estimates, spend from 50 percent to 80 percent of their time mired in this more mundane labor of collecting and preparing unruly digital data, before it can be explored for useful nuggets.” One data executive, “whose sensor-filled wristband and software track activity, sleep and food consumption, and suggest dietary and health tips based on the numbers,” complains how little this aspect of data analysis is appreciated by “data civilians.” The solution? But, of course – (almost) full automation of data collection, an effort spearheaded by a few promising startups. And how about all the research suggesting that insight is linked to intuition, and excessive analysis and overthinking – and particularly formal modeling – tend to suppress these “softer” aptitudes? I suspect most “data scientists” will hardly worry about this.
