As the first line says, it's about giving children more sense of control over their lives. Not more control, but more sense of control - it's not about reality but about their perception of it.
That's one of the many nuances here. You have to think about other things. When is illusion of control going to be harmful? When is the illusion going to crack? When is the illusion going to stick and become reality? When is increased control equivalent to removal of boundaries? When does it turn into abdication of parental responsibility? When does it reach levels of neglect? When is withdrawal from child's life going to make the child feel deserted?
There is no way to resolve these ambiguities upfront. You have to listen and observe. That's why parenting resembles conversation that is unique for every parent-child relationship and that evolves over time.
Following advice in this book or any of the many similar books is going to result in crude, clumsy parenting. Particularly so when authors argue for a side in order to stand out or to keep the book focused. That's why these books feel so artificial and kind of extremist.
Sense of control and control are not mutually exclusive and can bias either way. In fact a major issue in U.S. society today is that adults who actually do have a lot of control over their own lives, don't have a sense of control, and it leads to depression and anxiety.
The article is about parents creating space for kids to actually have more control, which will over time improve their sense of control.
It's not about fooling or manipulating kids. That's a pretty crazy interpretation that makes me wonder if you read it the whole way through.
