       It just occurred to me that since a lot of "scale of 1 to 10" or 5-point scale ratings are represented graphically as a line of filled stars, there is a subtle suggestion that average is better than average.
Here's how, schematically, Netflix and Amazon.com represent their customer ratings on a 5-point scale:
 
1: *.... 
2: **... 
3: ***.. 
4: ****. 
5: ***** 
 
A score of 3 looks pretty good, with 60% of the visual field filled in.  Even a score of 1 doesn't look so bad.  Nobody looks like a failure this way.
Amazon.com's textual interpretations of these scores are more to the point:
 
1: I hate it 
2: I don't like it 
3: It's OK 
4: I like it 
5: I love it 
 
A graphical representation that better reflects that "average means average" would look more like a gas gauge than a thermometer:
 
1: |.... 
2: .|... 
3: ..|.. 
4: ...|. 
5: ....|
