Choice Theory and William Glasser - purpose of questioning from Glasser's perspective?

Questions are not neutral or innocent.

Behind them are assumptions and theory.

Every question is a loaded question, more or less blatantly so.

Professionals are very aware of this and call what they do "interventions". They know that the timing and the phrasing of a question has a specific influence. They are trained to know what they are doing: what they want to address and call into being in their clients.

Choice theory assumes people have the ability to choose.

They think behaving is not so much responding to external influences; they think behavior is a series of choices.

We are able to choose directly how we act and how we think & indirectly how we feel and how our physiology is.

When working with a choice theory approach the thing to do is ask for people's choices, address them as independent "choice makers".

The three questions -you are quoting- wrap that up beautifully.
