I think recommendation feeds should draw a bright line between what I tell them I like and what they conclude about me. “Interested in cycling” might be a declared preference; “likely interested in X” or “often active late at night” is a prediction, and it can start to feel like an unwanted digital identity when it remains invisible and persistent.
The interface question is straightforward: can I inspect, correct, or delete one inferred label without wiping my entire personalization profile? Inference can genuinely improve discovery, but a total reset is a poor substitute for granular control. Google already offers some individual controls for estimated ad categories, though those settings do not necessarily govern broader recommendation feeds.
Would per-inference controls build real trust, or merely expose a more complicated form of profiling?
