> You wouldn't listen to someone who hasn't passed physics 1 about the whether the bridge you are building is stable.
It depends what they were saying about it. If they were claiming that it's obviously safe because it's made of steel, because steel is really strong, then no --- not even if they had a PhD in Physics and knew the exact tensile strength of the materials. But if they were mentioning that in their personal observation this particular bridge sure sways a lot when it's windy, I'd probably listen to them despite their lack of formal education: https://www.youtube.com/watch?v=qbOjxPCfaFk.
You're correct, but in the same way you'd trust the person to tell you about the symptoms of the bridge swaying, you can trust a person to tell you about the symptoms of everyday life. E.g. it's hard to find a job, minimum wage isn't enough to live on, I feel isolated, etc. But leave the higher level analysis to those more qualified, at least IMO.
