The Use of Trickery with Words
"..is not manipulative or coercive because the possibility of a person choosing differently is not closed down."
Does the definition of "manipulation" include a requirement that potential, options or choices are blocked? It's like a changing definition: if a person does realize they were told something different than it was formulated to appear, then they could potentially, optionally choose to follow the actual meaning of the words employed, like "manipulative" in the preceding quote, which was taken from an article about the development and political implementation of behavioral science (for instance, through nudges and opt-out frameworks) ("Invisible Manipulators of Your Mind" by Tamsin Shaw, The New York Review of Books, https://getpocket.com/explore/item/invisible-manipulators-of-your-mind).
It's supposedly for our own good, the way we want things, as an aid to battle our inherent laziness, but that's just a cover when such tricks are used for evil.
