While not a completely useless metric, it's also not a completely reliable metric either.
With having this thought, I have doubled down on trying to stay out of things I'm not personally knowledgeable about. For me, this means trying even harder to stay out of most kinds of political discussions, which frequently boil down to gossip and name calling and deciding which "people" you want to be seen as and who you want to be for and who you want to be against.
Political discussion tends to not be about good policy and what kinds of policies we want to have and why. And I have concluded I honestly don't know enough in most cases to have any idea which candidate I should be talking trash about or whatever. And it all too often ends up a case of me parroting sentiments of acquaintances just to try to connect socially.
I wonder how much that's true for other people/"in general." And I wonder if we need to revisit how politics gets done and revise our de facto use of popularity contests now that you are so unlikely to meet people you are voting for or know someone who actually met them and we are reliant on Facebook and what not, which has proven to be very much game-able.
The degree to which modern politics so often looks to me like the plot from "Wag the dog" is pretty disturbing.
Which isn't actually intended to take this into the direction of politics. It's just to say that rubrics of social proof that were probably more reliable when the world was a smaller place have gone weird places in the internet age and we maybe need to think about that more than we do and try to find solutions.
