Yes, and there's one more thing. Instead of making the other person responsible for your lack of understanding, which we all have done at some point, it's better to let them know that you don't understand their approach and let them explain better. Actually about half of the times their idea might be good, but they don't know how to explain it or maybe you can't grasp the whole thing because of a lack of context.
You know, explaining an idea to somebody, from scratch, it's the better way to develop it. If it's stupid they will realize. If it's good they'll get enthusiastic.
In a previous comment I mentioned that this is the tactic that my manager uses, and it works wonderfully: let people talk from the beginning and ask questions later.
Of course, if you end up disagreeing, even though if their idea is good, they'll like that you let them explain and took time to consider
