Thinking, Fast and Slow
#1
Thinking, Fast and Slow
There was a Horizon on TV last night about the work of Nobel Prize winner Daniel Kahneman. Horizon can be a bit hit and miss, but this was quite good.

He proposes two modes of thinking:
System 1: Fast, automatic, frequent, emotional, stereotypic, subconscious
System 2: Slow, effortful, infrequent, logical, calculating, conscious

What was interesting was that he said that we tend to make decisions based on system 1, then if we have to justify it afterwards we will use system 2, but this is not how we made the original decision. This can be observed with someone for example being told that a ghost is nearby, and then attributing a strange noise to that ghost because it fits that pattern. It could also explain the strange justifications used by Christians on this forum!

Also when using system 1 we evaluate things based on past experience, rather than using a new pattern of thinking. We do this all the time, and make mistakes based on this. E.g. I've met 3 Australians and they were fat, therefore all Australians are fat. We need system 2 to take over and provide rational thinking. It seems that system 1 is very prone to fallacy. However using system 2 is costly and we may not use it out of laziness.

I found it interesting anyway, and I can think of times when I've made mistakes by using the wrong system.

Yeah. It's scary to think that we might we inherently racist.

I've always thought that racism was down to stereotyping which was caused by brain "laziness", as it's a lot easier to store information that is compressed in this way. They didn't mention data compression on the program (well it is Horizon), so I've no idea if this is the reason.

Sounds like hot and cold cognition. Interesting. I saw his TED Talk recently. This guy is pretty brilliant.
"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great

That sounded really interesting, so I looked it up. Is this the right lecture?

That's the right person and right subject, so it's probably got far more depth than the Horizon episode.
