I could have used any other example in which emotionally strong counter theories has arisen.
I haven't seen any such theories, and when I specifically searched them out, I found nothing worth paying attention to. Clearly, we are accessing different news sources. Personally, I don't pay much attention to the news, and what little I hear is from the BBC, occasionally the better class of UK newspapers, and I'll look on Google News if there's something I specifically want to find news about.
Where do you find the news?
Real science works by investigating evidence.
On the Hebdo attack, there is plenty of evidence. The identities of the individual attackers are known. The manner of their attack suggests military experience. It is not yet clear what Islamic organisation they belonged to, if any, but no other type of organisation is suggested, and I think none needs to be. No-one is suggesting that this was anything but an Islamic terrorist attack, which it seems obvious to me that it was. Think horses, not zebras.
To find any conspiracy theories at all I had to specifically search for /hebdo conspiracy/ and only turned up stuff clearly not worth paying attention to, not even zebras, but unicorns.
See for example "Turkish president accuses 'the West' of being behind Charlie Hebdo attacks and deliberately 'blaming Muslims' reported in the UK's Daily Mail. It took me a few seconds to find this example there are many others.
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?
