Blame
Whenever someone makes an outrageous claim such as the infamous, "McDonald's made me fat," the knee-jerk response is to list for this person all the actual reasons they have acquired a less than desirable mountain climbing physique, because you can clearly see the lack of willpower and unwillingness to exercise and eat healthy, and why can't they?

Certainly I have once again been thinking about free will/choice, the human mind, and the automatic calculations it makes on a daily basis that somehow result in something as unreasonable as Vanilla Ice jumping a fence on a yellow motorcycle (I know, it sounds like I'm just stringing words together).

At one time, an orange jacket and splotchy colorful shorts were a wardrobe combo worthy of praise. In hindsight we have a good laugh and blame it on the bizarre logic system established in the 90's. But in reality no outfit is safe from time.

Eh, but I'm getting myself a little off topic here... What I was trying to point out was the general use of blame and praise in an attempt to make one's life better.
What I mean by that is how we as a species use this tagging system in order to create our own working models of reality.

The fat person blames McDonald's for being fat, and in a sense this might work for them, providing they stop eating there because it is what they believe to be the source of their unhappiness (we can presume them to be unhappy because they are not praising McDonald's for their current condition).

What we see that they don't are the boundaries they have placed on what I refer to as "blame proximity."
They only extend it as far as McDonald's, probably in an effort to avoid any real work.
However, if the boundaries of blame proximity were extended too far we could end up blaming Emperor Charlemagne.

I believe this is how black cats end up with such poor reputations.
