Gravedancer,
The paradox lies here: What is a rational person?
We assume that such a person exists. IMO, a rational person is someone who is less irrational than most.
Humans aren't made for making decisions and so forth. We can do it of course. We are capable of that and so much more.
But it's quite clear that our social development hijacks our naturally irrational behavior.
So quite often our irrational behavior wants to hijack back.
Am I making sense?
In essence, we are animals.
Or better said, we are computers with a huge amount of computing power but no built in master program. We have to upgrade the software we use on a continual basis or the hardware is good for nothing.
Hungry, to comment about decisions, I think that an ideal decision is one in which you cannot predict the outcome. Here, you cannot be wrong or right. You have all the information you can possibly gather to help you but there is still no clear verdict. This shouldn't be stressful to the well informed person; they know that any consequences could not have been forseen. (Or that one decision cannot be forseen as having more negative consequences) Therefore the outcome is not because of a wrong decision, but simply a product of uncertainty.
If you can predict the consequences before coming to a decision, then it's pretty simple: don't do what leads to the bad consequences.
But still, it's not for us to decide in hindsight what was a bad decision unless we know failed in our responsibility of collecting accurate data.
