Imagine if your demographic disproportionately heeds the author's advice while nobody else does. The first downside you might notice is when the next president gets elected on a platform of taxing your demographic into space, with zero opposition. You won't notice the coverage, obviously, but you will notice the decreased paycheck. You have not had to do much about what's in the news because your demographic have bee…
It's quite a jump from what's in the blog article to the claim that you end up "voting wrong". Actually, it seems to me you didn't pay any attention to what the text says at all. Please actually read it. The more I think about your point the less of a connection or relevance I see with the text I just read.
The article argues that you are better off 'switching off' from the media because you won't be doing anything about any of it anyway, other than having uninformed water cooler conversations.
The truth is, for the vast majority most of the news that's been happening for the vast majority of anybody's life, it's not worth doing anything about it, including investing the time to read books on the topics. Because, honestly, most of it is of no consequence to us, either way. And that's because the politicians know that people like us read the news and and are willing to spam social media and wreck their election chances at the slightest provocation, so policies that are against our interests are pre-filtered.
But it doesn't hold that this will always be true. If you and people like you grow complacent and block out the news altogether, one day you might notice that laws have been passed that oppress your demographic and your demographic alone. Because you didn't protest and the politicians know you wouldn't protest, because you switched off and they know that too.
This requires no ill-will on their part. It's just that their optimization function for re-election requires balancing the interests of only those who are willing to do something to protect their interests. Which necessarily requires them to be at least minimally informed. And for this, partial and shallow information is a lot better than no information at all.
The danger isn't that you end up 'voting wrong'. The danger is you'll stay home the day everybody else votes for the stormtroopers to kick your door in and take all your stuff.
