Earlier quoted context omitted.
I personally would hope that you take extra precaution with answers related to medicine/safety. Why would you trust google with something like this? If you ask Google "Can my dog eat X" and blindly trust the answer then it is your fault and not google's if your dog gets sick. Google isn't responsible for your dog, you are!
Why would you trust anything? Not to go to the extreme, but we do things every day where trust is integral, and what we trust is not something we verify independently. Or maybe you are different.
I accept googles answer when I ask for the weather. If google is wrong on this it mostly has no effect. So it is absolutely appropriate to accept this answer blindly.
I trust my doctor when I have a minor illness, but I did select my doctor carefully and I would get a second opinion if it is something serious.
Putting the same care into both of these things would either be dangerous or obsessive. It does terrify me that people here are suggesting that there are people who put less care into answering medical or safety related questions for themselves than I do reading a weather report for the day. It's crazy.
