Whats worse is that any type of rating system has an utter bias towards the very very upper end of the scale by it's consumers.

If you have a true rating system then 2.5/3 out of 5 means average or more or less what you should be looking for in most cases 4 is out standing and 5 is bloody icecream pooping unicorn.

You see this every where a rating system is implemented heck in entertainment movies and games don't fight from 0 to 100 anymore but form the 90-100 if you see any score below 90 or 4 stars people usually avoid that product.
