Is this surprising given that it is nearly impossible to get >50% of people to agree on any one topic?

Consider the opening line:

"Imagine that you are having trouble with your in-laws... You ask ChatGPT... It tells you not to try to win them over. Keep a respectful distance..."

I know people who would disagree. I know people who would agree.

The article shows the same thing, that asking more than one source yields more than one response.

It's the age old joke/commentary: Ask 10 philosophers the same question and you'll get 11 different answers.
