staying away from discussions of emotionally charged recent news
That's a strawman. Nobody argued here that it's bad to discuss recent news in general.
That, essentially, the idea that tabooing discussion of things that are emotionally charged is a way of tabooing a valuable part of learning to be less wrong .
That's not what "politics is the mindkiller" advocates. It advocates not using emotionally charged examples to make points that you could make with examples that are less emotionally charged.
If the OP wanted to specifically talk about the issue of the attacks and reasons to think that the official version of this specific event isn't correct he could have made a threat making an argument why the official story is wrong.
He didn't. He used it as an example for a larger class of events.
If he wanted to speak about the value in believing conspiracy theories he could have analysed a case like Princes Diana's death and the reasons for >0.01% believe that she was killed on purpose. The event happened years ago, so the evidence base is a lot better. There are interesting things to be said given how that case progressed. A case study that likely wouldn't use the term "real science".
After the terrorist attacks at Charlie Hebdo, conspiracy theories quickly arose about who was behind the attacks.
People who are critical to the west easily swallow such theories while pro-vest people just as easily find them ridiculous.
I guess we can agree that the most rational response would be to enter a state of aporia until sufficient evidence is at hand.
Yet very few people do so. People are guided by their previous understanding of the world, when judging new information. It sounds like a fine Bayesian approach for getting through life, but for real scientific knowledge, we can't rely on *prior* reasonings (even though these might involve Bayesian reasoning). Real science works by investigating evidence.
So, how do we characterise the human tendency to jump to conclusions that have simply been supplied by their sense of normativity. Is their a previously described bias that covers this case?
