If you seriously believe that the majority of Americans believe that judges are relatively unbiased, you need to spend some time with a lower class of people. And I'm not talking about middle class white kids pretending to be rebels.

EVERY convict I know (with one exception, and I'm not sure about him, it's been 20 years since he was in jail) and everyone who has ever tried to argue a child custody case, lost a small claims case, or whatever thought the judge was personally and malevolently biased against them for all sorts of reasons ranging from their haircut to the phase of the moon.

It's really only the upper middle class and the rich who think that judges are mostly unbiased, although many do think it's for racial or cultural reasons, most of them just don't want to admit that they are guilty.

In another vein, most of us DO think about "big" questions at different times, this is why they are "big" questions--we don't wake up in the morning and in between the time we finish grinding the beans and taking the first drink of coffee decide to quit or job designing and printing t-shirts for underground punk bands, drop back into school and get a masters in business management and go work for a Management Consulting company.

It's the important decisions that you can't put off (direct pressure, quick clot or tourniquet?) that you have to make RIGHT FUCKING NOW that you often have to make cold, wet, tired and hungry. And no, you're not at your best.

You are right that we need to be aware of how various factors impact our cognition. I get really fucking grumpy. Ok, grumpier when I'm fasting. Or when I'm tired. I get MUCH less tolerant of stupidity or ignorance (which is bad when dealing with a precocious 4 year old). I've had to work on complex problems when really tired, and I know (or at least I think I do) where my limits are. These days I live well inside them just in case.

I also keep some GU in my bag, or an energy bar or some sort in my backpack at all times. Because it helps.
