“Data about the real world is generated and collected in the real world. And when real-world things are measured and calculated by human beings, that data is subject to human imperfections – including flaws in the systems and structures that people use to generate and collect those numbers. Even data generated by machines is fallible. For example, your phone probably calculates your average screen time by adding up all the time it thinks you’ve spent looking at your phone. Most phones do this to help you better understand your phone habits. But a human had to decide what counts as “screen time” and how to calculate it and your phone might undercount or overcount your screen time based on those definitions. These kinds of machine-generated measurements might be useful, and they might even be mostly accurate but they’re not “objective” or unquestionable. So while I can use my own screen time reports to see that I’m probably spending waaay too many minutes on Instagram, the exact number of minutes isn’t something I take too seriously.”
