Stomach Monkey, you've reminded me that I left out appriorate level of scope as also being a problem.
Where I'm going with this:
1. Not finding important differences that can only appear as level of detail is increased.
2. The source data is not accurate at suffecient detail level.
Increasing the level of detail beyond the level of data would only result in unreliable pixels.
One cannot get an accurate picture without additional levels of detail in the data.
3. The problem of scope is looking at a single pixel or small group of pixels and judging the rest of the image unseen.
Racists would be people trapped in this problematic microscopic worldview.
The level of detail, the scope of the search, each of these must be appropriate to find an accurate result.
A good way to find the appriorate level is to increase scope or detail and see if the same findings remain.
The pixels one has control over should occupy one's decision making power rather than pixels where one's control is lacking.
On top of scope and detail there is also perspective.
