> Understanding other people
I used to do that too - with religion. Then I stopped because I believe that there are fundamental differences between rational and irrational people. The volume is on the side of the irrational ones, so I gave up.
I am better off avoiding these subjects now, as nobody ever convinced anybody.
> Therefore she made up her mind without doing the least research. That's stupidity
I am French and our news (following official governmental information) told us that masks are useless, then dangerous, then somehow useful, then life-saving.
Someone who is not that interested in the subject may have heard one of these opinions.
I am in the same boat when it comes to climate change and Brexit. There are zillions of opinions, but none of the ones I heard are clear cut.
I have a PhD in physics so I love numbers and equations. I am also painfully rational and yet I hear that the climate is warming globally, but this doe snot mean that this is visible on the small scale of my city, and then that in average the temperature of seas is raising, but the sea during my vacation is still cold. And why it matters that +2° here or there makes a difference.
Same for Brexit: this is an economic disaster, or a godsend - depending on whom you listen to. But nobody gives actual numbers. When I look at the EU budget, I see that the UK is a net payer. So UK leaving is bad for us, good for them. Except that it si not, because something.
I am not an expert in climate and in economy. And I do not want to be. I am open to having a well bundled rational set of information (and consequences) - it is just that I do not see them. For things like Brexit or climate change, they should be stuffed into my eyes daily.
When people start to wave hands instead of giving a few accurate and unbiased numbers, I conclude that they simply do not know, or are not sure.
BTW, the best, understandable argument about climate change was given to me by, who else, xkcd: https://xkcd.com/1732/, https://xkcd.com/1379/ and a few others.
