I suppose they cannot do that because it is just too obvious - "ask lots of closed questions. Get them to agree with you. Then start making suggestions about what they need to improve their life". It would give a different feel to the theocratic ministry school though.

When I lived in Australia my cousin sold life insurance and pensions for a time.

It was not considered very funny.
