That might be true to some extent. Typically when you’re teaching someone, you probably ask them what they expect to happen or show them likely responses that don’t work out, and show them why.

I don’t think it’s a big issue, provided it’s labelled clearly as a mistake, which I believe was one of @gennan’s points.
