I think you overestimate how much people want an actual truthful answer. I think people are often looking things up to silence a nagging voice in the back of their heads, or settle an argument to be able to move on. In those cases, no decision is riding on the answer, and a quick answer, even when factually incorrect, could be argued to serve the purpose just as well as (or better than) a slow but more correct answer.
I realised this for myself when I read Sivers on being without internet[1]. He discovered a process to silence the nagging voice without searching:
> When I’m yearning to search, I ask myself why.
> - What answer am I hoping to hear?
> - What answer would be a surprise?
> - What would I do in each case?
