This could be for any number of reasons. The reason I was thinking of this, was realizing that there are certain topics that I could probably find the answers to online, but I happen to have a friend who is an expert in that field. So it's usually easier to ask them, and trust that their answer is either accurate or that they will tell me "I don't know".

The other aspect of it was, there are certain topics that are likely to be extremely "noisy" with disinformation (intentional or otherwise) or ads online, and so I'll avoid trying to research them and instead ask a friend.
