Perfect rationality and superrationality are concepts from economics. I try to refrain from making shit up..Psychoserenity wrote:I mean the rationality people use on a day to day basis, as opposed to - well thought out rational judgements made with all the available evidence - or even a superrationality as you put it.Comte de Saint-Germain wrote:What is day to day rationality?Psychoserenity wrote:I think what he's getting at is the middle-world thing - though perhaps ant and skyscraper don't go far enough to make it clear. In scales beyond those in which we have evolved, the universe gets very strange. Take quantum mechanics or relativity. Day to day rationality just cant apply there. We can use high tech instrements to get data, and abstract mathematics to understand it, but we cant then apply this information to decisions about what we want to buy from the shops, despite the fact that it does make a difference.devogue wrote:I don't understand this BAA.born-again-atheist wrote:It is impossible to be completely rational simply because the human mind can not comprehend anything larger than the immediate scale of itself. Try imagining yourself in relation to an ant, and then yourself in relation to a skyscraper. Now try imagining the ant in relation to the skyscraper.
I don't have to imagine myself in relation to an ant - I can stand beside it and it's reality. Likewise for a skyscraper.
As for imagining the ant and the skyscraper - well, the ant is a lot smaller than me, and the skyscraper is a lot bigger, so I'll imagine myself in relation to, say, Ireland. I can do that because I know the geography, distances, times involved in travelling compared to my size.
Maybe I'm missing the point completely.![]()

By the way, you are defining concepts into empirical categories, that's permissible only because empirical evidence agrees with you, but it isn't going to win you favours with someone who disagrees with you.
You mean that the whole point of the scale example was to say that human beings are unable to completely predict the outcome of their behaviour, and that therefore perfectly rational choices are impossible? Odd.It's not about imagining it - it's the fact that we can't comprehend how every quantum event will will change our lives, so we can't take them into account when trying to make a decision, therefore, as BAA said, it is impossible to be completely rational.Also, you forgot to explain what our failure to 'imagine' what an atom looks like has to do with human rationality.
Not sure whether I understand the difference. Empiricism demands that ascribed traits must be measurable. In humans this means that they are measurable in behaviour (phrenology went out of fashion). Consequently, saying that someone behaves rationally isn't very different from saying he is rational, no, I would not say. Of course, this is more philosophy that cognitive psychology..Ok good.For one, empirical data that shows that humans don't make rational judgements, are bad at statistical understanding and generally aren't built to do well in various games (like the reiterated prisoner's dilemma).Now back on topic, for the limited rationality we are capable of, do you think that it, and kindness, loyalty, honesty etc. are intrinsic aspects of specific individuals, or is it more useful to think of them as temporary acts that we are all capable of?
