But the sick part is the asymmetry: the company(ies) know, and the individuals don't. Would an individual change their practices if they were told that something they were doing was harmful? But, they were never given that choice. Instead, the data is collected, categorized, and sold. Insurance companies can collaborate all the data and extrapolate trends at scale. Now, these insurance companies also have a fiduciary responsibility to lower costs and raise profits to their shareholders. What that amounts is that every insurance company will have to do the same, with slight variations. But we the populace will be worse off with unknown black boxes saying worse things about us (mortality, health, safety) and for us few ways to change things aside gross generalizations our doctors give us.
