Simple Data Transformation Question

[KUJustin]

I'm looking for some ideas on how to transform some data I'm working with.

Basically I have a bunch of "average ratings" from some survey data. A number of attributes have been rated by multiple people from 1 to 7. The "average ratings" are generally between 4 and 5 (mean: 4.6, stdev: .7).

I'm looking for a systematic way to "spread out" the data so the values aren't all in the 4 to 5 range. Basically I want to flatten my bell curve.

I've got a handful of ideas I'm just curious what you guys would see as a good way of going about this because I have virtually no formal statistics training.
