Ah that's always SO fun. It doesn't matter how "smart" the person actually are (or think they are) we are ALL susceptible to influence and blind tests are shockingly simple to implement.
Convinced you can distinguish A from B? Ok! No problem, let's try! Can be at the dinner table for fancy wine or with agents, it's all the same, you try an option, another option, maybe all options from the same, and if you reliably can't tell well kudos, you are just like the rest of us!
It's easy to "know" in retrospect but blind test is where genuine difference can be found. Or not.
Isn’t this obvious?
Over half of HN commentators visibly struggle to piece 3 or more complex ideas together.
How could anyone, who spent more than 30 minutes reading HN, expect otherwise?
It’s also true in every other realm. Governments, think tanks, political parties, and activist groups use propaganda because it works.
I sometimes wonder how much of what I believe is bullshit I was fed through intentional propaganda. I do think as I’ve gotten older I’ve gradually identified and challenged some of it.
