Good question!

At a church meeting, questions were invited from the floor.

There were two questions that must have been really good (I don't know what a 'really good' question would be. Perhaps one that sought information that the asker did not have would be good).

After each one, the moderator said 'That's a good question.'

NEVER judge a question. Instantly you start to grade the questions that are 'good', you grade all of them that's aren't good by your judgement as 'not good'. People who don't want to feel belittled will not risk asking a question that will be 'not good'. But, theirs might have been the most useful question for others.

When you are moderating a group, instructing a class, conducting a seminar, you want questions, right? Then none are good, bad, indifferent stupid or boring.

This is what you say:

1. Just answer the question
2. Repeat the question for others and to check your own understanding of it, then answer it, or ask if others have a view
3. Thank the asker, then answer it.
4. Admit that the question challenges you, you might need to think about it.

 DO NOT, EVER, EVER GRADE A QUESTION AS GOOD.
