People are always dumber than they think they are, remember that. It's best if you can keep your cool and ask questions that dismantle the premise without seeming like you have an agenda. (Yes, it's unfair that you have to do this. Deal.) Questions that others are suggesting like "what's your evidence for that?" are way too pointed to say directly in a business setting. Sadly, it's better to be less direct than that. Frame your questions as if you were learning rather than challenging a viewpoint (which is what you're actually doing). A book like "Games People Play" (Eric Berne) may help with this.
